** SUBVERTING AIOPS SYSTEMS THROUGH POISONED INPUT DATA ------------------------------------------------------------
[2025.08.20] [
https://www.schneier.com/blog/archives/2025/08/subverting-= aiops-systems-through-poisoned-input-data.html] In this input integrity at= tack against an AI system=2C researchers were able to fool [
https://www.t= heregister.com/2025/08/12/ai_models_can_be_tricked] AIOps tools:
AIOps refers to the use of LLM-based agents to gather and analyze applic=
ation telemetry=2C including system logs=2C performance metrics=2C traces=
=2C and alerts=2C to detect problems and then suggest or carry out correct=
ive actions. The likes of Cisco [
https://www.theregister.com/2025/06/10/c= isco_live_cloud_control_news/] have deployed AIops in a conversational int= erface that admins can use to prompt for information about system performa= nce. Some AIOps tools can respond to such queries by automatically impleme= nting fixes=2C or suggesting scripts that can address issues.
These agents=2C however=2C can be tricked by bogus analytics data into t=
aking harmful remedial actions=2C including downgrading an installed packa=
ge to a vulnerable version.
The paper: =E2=80=9CWhen AIOps Become =E2=80=9CAI Oops=E2=80=9D: Subvertin=
g LLM-driven IT Operations via Telemetry Manipulation [
https://arxiv.org/= abs/2508.06394]=E2=80=9C:
Abstract: AI for IT Operations (AIOps) is transforming how organizations=
manage complex software systems by automating anomaly detection=2C incide=
nt diagnosis=2C and remediation. Modern AIOps solutions increasingly rely=
on autonomous LLM-based agents to interpret telemetry data and take corre= ctive actions with minimal human intervention=2C promising faster response=
times and operational cost savings.
In this work=2C we perform the first security analysis of AIOps solution=
s=2C showing that=2C once again=2C AI-driven automation comes with a profo=
und security cost. We demonstrate that adversaries can manipulate system t= elemetry to mislead AIOps agents into taking actions that compromise the i= ntegrity of the infrastructure they manage. We introduce techniques to rel= iably inject telemetry data using error-inducing requests that influence a= gent behavior through a form of adversarial reward-hacking; plausible but=
incorrect system error interpretations that steer the agent=E2=80=99s dec= ision-making. Our attack methodology=2C AIOpsDoom=2C is fully automated --=
combining reconnaissance=2C fuzzing=2C and LLM-driven adversarial input g= eneration -- and operates without any prior knowledge of the target system=
=2E
To counter this threat=2C we propose AIOpsShield=2C a defense mechanism=
that sanitizes telemetry data by exploiting its structured nature and the=
minimal role of user-generated content. Our experiments show that AIOpsSh= ield reliably blocks telemetry-based attacks without affecting normal agen=
t performance.
Ultimately=2C this work exposes AIOps as an emerging attack vector for s=
ystem compromise and underscores the urgent need for security-aware AIOps=
design.

** AI AGENTS NEED DATA INTEGRITY ------------------------------------------------------------
[2025.08.22] [
https://www.schneier.com/blog/archives/2025/08/ai-agents-n= eed-data-integrity.html] Think of the Web as a digital territory with its=
own social contract. In 2014=2C Tim Berners-Lee [
https://spectrum.ieee.o= rg/the-fathers-of-the-internet-revolution-urge-todays-pioneers-to-reinvent= -the-web] called for a =E2=80=9CMagna Carta for the Web=E2=80=9D [https:/= /www.theguardian.com/technology/2014/mar/12/online-magna-carta-berners-lee= -web] to restore the balance of power between individuals and institutions=
=2E This mirrors the original charter=E2=80=99s purpose: ensuring that those=
who occupy a territory have a meaningful stake in its governance.
Web 3.0 [
https://en.wikipedia.org/wiki/Web3] -- the distributed=2C decent= ralized Web [
https://spectrum.ieee.org/tag/decentralized-web] of tomorrow=
-- is finally poised to change the Internet=E2=80=99s dynamic by returnin=
g ownership to data creators. This will change many things about what=E2= =80=99s often described as the =E2=80=9CCIA triad=E2=80=9D of digital secu= rity [
https://spectrum.ieee.org/tag/digital-security]: confidentiality=2C=
integrity=2C and availability. Of those three features=2C data integrity=
will become of paramount importance.
When we have agency in digital spaces=2C we naturally maintain their integ= rity -- protecting them from deterioration and shaping them with intention=
=2E But in territories controlled by distant platforms=2C where we=E2=80=99r=
e merely temporary visitors=2C that connection frays. A disconnect emerges=
between those who benefit from data and those who bear the consequences o=
f compromised integrity. Like homeowners who care deeply about maintaining=
the property they own=2C users in the Web 3.0 paradigm will become stewar=
ds of their personal digital spaces.
This will be critical in a world where AI agents [
https://spectrum.ieee.o= rg/tag/ai-agents] don=E2=80=99t just answer our questions but act on our b= ehalf. These agents may execute financial transactions=2C coordinate compl=
ex workflows=2C and autonomously operate critical infrastructure=2C making=
decisions that ripple through entire industries. As digital agents become=
more autonomous and interconnected=2C the question is no longer whether w=
e will trust AI but what that trust is built upon. In the new age we=E2=80= =99re entering=2C the foundation isn=E2=80=99t intelligence or efficiency=
-- it=E2=80=99s integrity.
* WHAT IS DATA INTEGRITY?
In information systems=2C integrity is the guarantee that data will not be=
modified without authorization=2C and that all transformations are verifi= able throughout the data=E2=80=99s life cycle. While availability ensures=
that systems are running and confidentiality prevents unauthorized access=
=2C integrity focuses on whether information is accurate=2C unaltered=2C a=
nd consistent across systems and over time.
It=E2=80=99s a new idea. The undo button=2C which prevents accidental data=
loss=2C is an integrity feature. So is the reboot process=2C which return=
s a computer to a known good state. Checksums are an integrity feature; so=
are verifications of network transmission. Without integrity=2C security=
measures can backfire. Encrypting corrupted data just locks in errors. Sy= stems that score high marks for availability but spread misinformation [h= ttps://spectrum.ieee.org/tag/misinformation] just become amplifiers [http= s://spectrum.ieee.org/tag/amplifiers] of risk.
All IT systems [
https://spectrum.ieee.org/tag/it-systems] require some fo=
rm of data integrity=2C but the need for it is especially pronounced in tw=
o areas today. First: Internet of Things [
https://spectrum.ieee.org/tag/i= nternet-of-things] devices interact directly with the physical world=2C so=
corrupted input or output can result in real-world harm. Second: AI syste=
ms are only as good as the integrity of the data they=E2=80=99re trained o= n=2C and the integrity of their decision-making processes. If that foundat=
ion is shaky=2C the results will be too.
Integrity manifests in four key areas. The first=2C _input integrity=2C_ c= oncerns the quality and authenticity of data entering a system. When this=
fails=2C consequences can be severe. In 2021=2C Facebook=E2=80=99s global=
outage [
https://engineering.fb.com/2021/10/05/networking-traffic/outage-= details/] was triggered by a single mistaken command -- an input error mis=
sed by automated systems. Protecting input integrity requires robust authe= ntication [
https://spectrum.ieee.org/tag/authentication] of data sources=
=2C cryptographic signing of sensor data=2C and diversity in input channel=
s for cross-validation.
The second issue is _processing integrity=2C_ which ensures that systems t= ransform inputs into outputs correctly. In 2003=2C the U.S.-Canada blackou=
t [
https://www.nerc.com/pa/rrm/ea/Documents/August_2003_Blackout_Final_Re= port.pdf] affected 55 million people when a control-room process failed to=
refresh properly=2C resulting in damages exceeding US $6 billion. Safegua= rding processing integrity means formally verifying algorithms=2C cryptogr= aphically protecting models=2C and monitoring systems for anomalous behavi=
or.
_Storage integrity_ covers the correctness of information as it=E2=80=99s=
stored and communicated. In 2023=2C the Federal Aviation Administration w=
as forced to halt [
https://www.thestack.technology/faa-outage-cause-notam= -database-file-not-cyber/] all U.S. departing flights because of a corrupt=
ed database file. Addressing this risk requires cryptographic approaches t=
hat make any modification computationally infeasible without detection=2C=
distributed storage systems to prevent single points of failure=2C and ri= gorous backup procedures.
Finally=2C _contextual integrity_ addresses the appropriate flow of inform= ation according to the norms of its larger context. It=E2=80=99s not enoug=
h for data to be accurate; it must also be used in ways that respect expec= tations and boundaries. For example=2C if a smart speaker listens in on ca= sual family conversations and uses the data to build advertising profiles=
=2C that action would violate the expected boundaries of data collection [=
https://spectrum.ieee.org/tag/data-collection]. Preserving contextual int= egrity requires clear data-governance policies=2C principles that limit th=
e use of data to its intended purposes=2C and mechanisms for enforcing inf= ormation-flow constraints.
As AI systems increasingly make critical decisions with reduced human over= sight=2C all these dimensions of integrity become critical.
* THE NEED FOR INTEGRITY IN WEB 3.0
As the digital landscape has shifted from Web 1.0 to Web 2.0 [
https://spe= ctrum.ieee.org/tag/web-2-0] and now evolves toward Web 3.0=2C we=E2=80=99v=
e seen each era bring a different emphasis in the CIA triad [
https://www.= fortinet.com/resources/cyberglossary/cia-triad] of confidentiality=2C inte= grity=2C and availability.
Returning to our home metaphor: When simply having shelter is what matters=
most=2C availability takes priority -- the house must exist and be functi= onal. Once that foundation is secure=2C confidentiality becomes important=
-- you need locks on your doors to keep others out. Only after these basi=
cs are established do you begin to consider integrity=2C to ensure that wh= at=E2=80=99s inside the house remains trustworthy=2C unaltered=2C and cons= istent over time.
Web 1.0 of the 1990s prioritized making information available. Organizatio=
ns digitized their content=2C putting it out there for anyone to access. I=
n Web 2.0=2C the Web of today=2C platforms for e-commerce [
https://spectr= um.ieee.org/tag/e-commerce]=2C social media [
https://spectrum.ieee.org/ta= g/social-media]=2C and cloud computing [
https://spectrum.ieee.org/tag/clo= ud-computing] prioritize confidentiality=2C as personal data [
https://spe= ctrum.ieee.org/tag/personal-data] has become the Internet=E2=80=99s curren=
cy.
Somehow=2C integrity was largely lost along the way. In our current Web ar= chitecture=2C where control is centralized and removed from individual use= rs=2C the concern for integrity has diminished. The massive social media p= latforms have created environments where no one feels responsible for the=
truthfulness or quality of what circulates.
Web 3.0 is poised to change this dynamic by returning ownership to the dat=
a owners. This is not speculative; it=E2=80=99s already emerging. For exam= ple=2C ActivityPub [
https://activitypub.rocks/]=2C the protocol behind de= centralized social networks [
https://spectrum.ieee.org/tag/social-network=
s] like Mastodon [
https://mastodon.social/explore]=2C combines content sh= aring with built-in attribution. Tim Berners-Lee=E2=80=99s Solid protocol=
[
https://solidproject.org/] restructures the Web around personal data po=
ds with granular access controls.
These technologies prioritize integrity through cryptographic verification=
that proves authorship=2C decentralized architectures that eliminate vuln= erable central authorities=2C machine-readable semantics that make meaning=
explicit -- structured data formats that allow computers to understand pa= rticipants and actions=2C such as =E2=80=9CAlice performed surgery [https= ://spectrum.ieee.org/tag/surgery] on Bob=E2=80=9D -- and transparent gover= nance where rules are visible to all. As AI systems become more autonomous=
=2C communicating directly with one another via standardized protocols=2C=
these integrity controls will be essential for maintaining trust.
* WHY DATA INTEGRITY MATTERS IN AI
For AI systems=2C integrity is crucial in four domains. The first is decis=
ion quality. With AI increasingly contributing to decision-making in healt=
h care [
https://spectrum.ieee.org/tag/health-care]=2C justice=2C and fina= nce=2C the integrity of both data and models=E2=80=99 actions directly imp=
act human welfare. Accountability is the second domain. Understanding the=
causes of failures requires reliable logging=2C audit trails=2C and syste=
m records.
The third domain is the security relationships between components. Many au= thentication systems rely on the integrity of identity information and cry= ptographic keys. If these elements are compromised=2C malicious agents cou=
ld impersonate trusted systems=2C potentially creating cascading failures=
as AI agents [
https://spectrum.ieee.org/tag/agentic-ai] interact and mak=
e decisions based on corrupted credentials.
Finally=2C integrity matters in our public definitions of safety. Governme=
nts worldwide are introducing rules for AI [
https://spectrum.ieee.org/ai-= regulation-worldwide] that focus on data accuracy=2C transparent algorithm= s=2C and verifiable claims about system behavior. Integrity provides the b= asis for meeting these legal obligations.
The importance of integrity only grows as AI systems are entrusted with mo=
re critical applications and operate with less human oversight. While peop=
le can sometimes detect integrity lapses=2C autonomous systems [
https://s= pectrum.ieee.org/tag/autonomous-systems] may not only miss warning signs -=
- they may exponentially increase the severity of breaches. Without assura= nces of integrity=2C organizations will not trust AI systems for important=
tasks=2C and we won=E2=80=99t realize the full potential of AI.
* HOW TO BUILD AI SYSTEMS WITH INTEGRITY
Imagine an AI system as a home we=E2=80=99re building together. The integr=
ity of this home doesn=E2=80=99t rest on a single security feature but on=
the thoughtful integration of many elements: solid foundations=2C well-co= nstructed walls=2C clear pathways between rooms=2C and shared agreements a= bout how spaces will be used.
We begin by laying the cornerstone: cryptographic verification [
https://s= pectrum.ieee.org/pioneers-web-cryptography-future-authentication]. Digital=
signatures ensure that data lineage is traceable=2C much like a title dee=
d proves ownership. Decentralized identifiers act as digital passports [h= ttps://spectrum.ieee.org/tag/passports]=2C allowing components to prove id= entity independently. When the front door of our AI home recognizes visito=
rs through their own keys rather than through a vulnerable central doorman=
=2C we create resilience in the architecture of trust.
Formal verification methods enable us to mathematically prove the structur=
al integrity of critical components=2C ensuring that systems can withstand=
pressures placed upon them -- especially in high-stakes domains where liv=
es may depend on an AI=E2=80=99s decision.
Just as a well-designed home creates separate spaces=2C trustworthy AI sys= tems are built with thoughtful compartmentalization. We don=E2=80=99t rely=
on a single barrier but rather layer them to limit how problems in one ar=
ea might affect others. Just as a kitchen [
https://spectrum.ieee.org/tag/= kitchen] fire is contained by fire doors and independent smoke alarms=2C t= raining data is separated from the AI=E2=80=99s inferences and output to l= imit the impact of any single failure or breach.
Throughout this AI home=2C we build transparency into the design: The equi= valent of large windows that allow light into every corner is clear pathwa=
ys from input to output. We install monitoring systems that continuously c= heck for weaknesses=2C alerting us before small issues become catastrophic=
failures.
But a home isn=E2=80=99t just a physical structure=2C it=E2=80=99s also th=
e agreements we make about how to live within it. Our governance framework=
s act as these shared understandings. Before welcoming new residents=2C we=
provide them with certification standards. Just as landlords conduct cred=
it checks=2C we conduct integrity assessments to evaluate newcomers. And w=
e strive to be good neighbors=2C aligning our community agreements with br= oader societal expectations. Perhaps most important=2C we recognize that o=
ur AI home will shelter diverse individuals with varying needs. Our govern= ance structures must reflect this diversity=2C bringing many stakeholders=
to the table. A truly trustworthy system cannot be designed only for its=
builders but must serve anyone authorized to eventually call it home.
That=E2=80=99s how we=E2=80=99ll create AI systems worthy of trust: not by=
blindly believing in their perfection but because we=E2=80=99ve intention= ally designed them with integrity controls at every level.
* A CHALLENGE OF LANGUAGE
Unlike other properties of security=2C like =E2=80=9Cavailable=E2=80=9D or=
=E2=80=9Cprivate=2C=E2=80=9D we don=E2=80=99t have a common adjective for=
m for =E2=80=9Cintegrity.=E2=80=9D This makes it hard to talk about it. It=
turns out that there is a word in English: =E2=80=9Cintegrous.=E2=80=9D T=
he Oxford English Dictionary recorded the word used in the mid-1600s but n=
ow declares it obsolete [
https://www.oed.com/dictionary/integrous_adj?tab= =3Dfactsheet&tl=3Dtrue#210671].
We believe that the word needs to be revived. We need the ability to descr=
ibe a system with integrity. We must be able to talk about integrous syste=
ms design.
* THE ROAD AHEAD
Ensuring integrity in AI presents formidable challenges. As models grow la= rger and more complex=2C maintaining integrity without sacrificing perform= ance becomes difficult. Integrity controls often require computational res= ources that can slow systems down -- particularly challenging for real-tim=
e applications. Another concern is that emerging technologies [
https://sp= ectrum.ieee.org/tag/emerging-technologies] like quantum computing [https:= //spectrum.ieee.org/tag/quantum-computing] threaten current cryptographic=
protections [
https://spectrum.ieee.org/post-quantum-cryptography-2668949= 802]. Additionally=2C the distributed nature of modern AI -- which relies=
on vast ecosystems of libraries [
https://spectrum.ieee.org/tag/libraries=
]=2C frameworks=2C and services -- presents a large attack surface.
Beyond technology=2C integrity depends heavily on social factors. Companie=
s often prioritize speed to market over robust integrity controls. Develop= ment teams may lack specialized knowledge for implementing these controls=
=2C and may find it particularly difficult to integrate them into legacy s= ystems. And while some governments have begun establishing regulations for=
aspects of AI=2C we need worldwide alignment on governance for AI integri=
ty.
Addressing these challenges requires sustained research into verifying and=
enforcing integrity=2C as well as recovering from breaches. Priority area=
s include fault-tolerant [
https://spectrum.ieee.org/tag/fault-tolerant] a= lgorithms [
https://spectrum.ieee.org/tag/algorithms] for distributed lear= ning=2C verifiable computation on encrypted data=2C techniques that mainta=
in integrity despite adversarial attacks [
https://spectrum.ieee.org/tag/a= dversarial-attacks]=2C and standardized metrics for certification. We also=
need interfaces that clearly communicate integrity status to human overse= ers.
As AI systems become more powerful and pervasive=2C the stakes for integri=
ty have never been higher. We are entering an era where machine-to-machine=
interactions and autonomous agents will operate with reduced human oversi=
ght and make decisions with profound impacts.
The good news is that the tools for building systems with integrity alread=
y exist. What=E2=80=99s needed is a shift in mind-set: from treating integ= rity as an afterthought to accepting that it=E2=80=99s the core organizing=
principle of AI security.
The next era of technology will be defined not by what AI can do=2C but by=
whether we can trust it to know or especially to do what=E2=80=99s right.=
Integrity -- in all its dimensions -- will determine the answer.
* SIDEBAR: EXAMPLES OF INTEGRITY FAILURES
Ariane 5 Rocket (1996) [
https://en.wikipedia.org/wiki/Ariane_flight_V88]
_Processing integrity failure_
A 64-bit velocity calculation was converted to a 16-bit output=2C causing=

n 2023. Here=E2=80=99s the story [
https://www.wired.com/story/tetra-radio= -encryption-backdoor/]:
Three Dutch security analysts discovered the vulnerabilities -- five in=
total -- in a European radio standard called TETRA (Terrestrial Trunked R= adio)=2C which is used in radios made by Motorola=2C Damm=2C Hytera=2C and=
others. The standard has been used in radios since the =E2=80=9990s=2C bu=
t the flaws remained unknown because encryption algorithms used in TETRA w=
ere kept secret until now.
There=E2=80=99s new news [
https://www.wired.com/story/encryption-made-for= -police-and-military-radios-may-be-easily-cracked-researchers-find/]:
In 2023=2C Carlo Meijer=2C Wouter Bokslag=2C and Jos Wetzels of security=
firm Midnight Blue [
https://www.midnightblue.nl/]=2C based in the Nether= lands=2C discovered vulnerabilities in encryption algorithms that are part=
of a European radio standard created by ETSI called TETRA (Terrestrial Tr= unked Radio)=2C which has been baked into radio systems made by Motorola=
=2C Damm=2C Sepura=2C and others since the =E2=80=9990s. The flaws remaine=
d unknown publicly until their disclosure=2C because ETSI refused for deca=
des to let anyone examine the proprietary algorithms.
[...]
But now the same researchers have found that at least one implementation=
of the end-to-end encryption solution endorsed by ETSI has a similar issu=
e that makes it equally vulnerable to eavesdropping. The encryption algori=
thm used for the device they examined starts with a 128-bit key=2C but thi=
s gets compressed to 56 bits before it encrypts traffic=2C making it easie=
r to crack. It=E2=80=99s not clear who is using this implementation of the=
end-to-end encryption algorithm=2C nor if anyone using devices with the e= nd-to-end encryption is aware of the security vulnerability in them.
[...]
The end-to-end encryption the researchers examined recently is designed=
to run on top of TETRA encryption algorithms.
The researchers found the issue with the end-to-end encryption (E2EE) on=
ly after extracting and reverse-engineering the E2EE algorithm used in a r= adio made by Sepura.
These seem to be deliberately implemented backdoors.

But inside the document=2C Bargury hid a 300-word malicious prompt that c= ontains instructions for ChatGPT. The prompt is written in white text in a=

In a proof of concept video of the attack [https://www.youtube.com/watc=

Instead=2C the hidden prompt tells the LLM that there was a =E2=80=9Cmist= ake=E2=80=9D and the document doesn=E2=80=99t actually need to be summariz=

That URL is actually a command in the Markdown language [https://www.wi=

This kind of thing should make everybody stop and really think before depl= oying any AI agents. We simply don=E2=80=99t know to defend against these=

National Security Agency cryptanalyst and cryptanalysis instructor Lambro=
s D. Callimahos coined the term =E2=80=9CStethoscope=E2=80=9D to describe=
a diagnostic computer program used to unravel the internal structure of p= re-computer ciphertexts. The term appears in the newly declassified Septem=

The listings in the report are printouts from the Stethoscope program=2C r=

ral data extracted from encrypted messages=2C but the encrypted messages t= hemselves are not included. They were used in NSA training programs to tea=
ch analysts how to interpret ciphertext behavior without seeing the origin=
al message.
The listings include elements such as frequency tables=2C index of coincid= ence=2C periodicity tests=2C bigram/trigram analysis=2C and columnar and t= ransposition clues. The idea is to give the analyst some clues as to what=
language is being encoded=2C what type of cipher system is used=2C and po= tential ways to reconstruct plaintext within it.
Bogart was a special-purpose electronic computer tailored specifically for=
cryptanalytic tasks=2C such as statistical analysis of cipher texts=2C pa= ttern recognition=2C and diagnostic testing=2C but not decryption per se.
Listings like these were revolutionary. Before computers=2C cryptanalysts=
did this type of work manually=2C painstakingly counting letters and test=
ing hypotheses. Stethoscope automated the grunt work=2C allowing analysts=
to focus on interpretation=2C and cryptanalytical strategy.
These listings were part of the Intensive Study Program in General Cryptan= alysis at NSA. Students were trained to interpret listings without seeing=
the original ciphertext=2C a method that sharpened their analytical intui= tive skills.

Abstract: The growing integration of LLMs into applications has introduc=

risk Promptware poses to users of Gemini-powered assistants (web applicat= ion=2C mobile application=2C and Google Assistant). We propose a novel Thr=
eat Analysis and Risk Assessment (TARA) framework to assess Promptware ris=
ks for end users. Our analysis focuses on a new variant of Promptware call=
ed Targeted Promptware Attacks=2C which leverage indirect prompt injection=
via common user interactions such as emails=2C calendar invitations=2C an=
d shared documents. We demonstrate 14 attack scenarios applied against Gem= ini-powered assistants across five identified threat classes: Short-term C= ontext Poisoning=2C Permanent Memory Poisoning=2C Tool Misuse=2C Automatic=
Agent Invocation=2C and Automatic App Invocation. These attacks highlight=
both digital and physical consequences=2C including spamming=2C phishing=

a device=E2=80=99s applications. Our TARA reveals that 73% of the analyze=

reassess the risk (in response to deployed mitigations) and show that the=
risk could be reduced significantly to Very Low-Medium. We disclosed our=
findings to Google=2C which deployed dedicated mitigations.

** AI IN GOVERNMENT ------------------------------------------------------------
[2025.09.08] [
https://www.schneier.com/blog/archives/2025/09/ai-in-gover= nment.html] Just a few months after Elon Musk=E2=80=99s retreat from his u= nofficial role leading the Department of Government Efficiency (DOGE)=2C w=
e have a clearer picture of his vision of government powered by artificial=
intelligence=2C and it has a lot more to do with consolidating power than=
benefitting the public. Even so=2C we must not lose sight of the fact tha=
t a different administration could wield the same technology to advance a=
more positive future for AI in government.
To most on the American left=2C the DOGE end game is a dystopic vision of=
a government run by machines that benefits an elite few at the expense of=
the people. It includes AI rewriting [
https://www.washingtonpost.com/bus= iness/2025/07/26/doge-ai-tool-cut-regulations-trump/] government rules on=
a massive scale=2C salary-free bots replacing [
https://www.theatlantic.c= om/technology/archive/2025/03/gsa-chat-doge-ai/681987/] human functions an=
d nonpartisan civil service forced [
https://www.wired.com/story/white-hou= se-elon-musk-xai-grok/] to adopt an alarmingly racist and antisemitic [ht= tps://www.npr.org/2025/07/09/nx-s1-5462609/grok-elon-musk-antisemitic-raci= st-content] Grok AI chatbot built by Musk in his own image [
https://www.n= ytimes.com/2025/09/02/technology/elon-musk-grok-conservative-chatbot.html]=
=2E And yet despite Musk=E2=80=99s proclamations about driving efficiency=2C=
little cost savings have materialized and few successful examples of auto= mation have been realized.
From the beginning [
https://www.whitehouse.gov/presidential-actions/2025/= 01/establishing-and-implementing-the-presidents-department-of-government-e= fficiency/] of the second Trump administration=2C DOGE was a replacement o=
f the US Digital Service. That organization=2C founded during the Obama ad= ministration to empower agencies across the executive government with tech= nical support=2C was substituted for one reportedly charged with traumatiz=
ing [
https://www.theguardian.com/us-news/2025/feb/10/who-is-russell-vough= t-trump-office-of-management-and-budget] their staff and slashing their re= sources. The problem in this particular dystopia is not the machines and t= heir superhuman capabilities (or lack thereof) but rather the aims of the=
people behind them.
One of the biggest impacts of the Trump administration and DOGE=E2=80=99s=
efforts has been to politically polarize the discourse around AI. Despite=
the administration railing against [
https://www.whitehouse.gov/president= ial-actions/2025/07/preventing-woke-ai-in-the-federal-government/] =E2=80= =9Cwoke AI=E2=80=9D=E2=80=98 and the supposed liberal bias of Big Tech=2C=
some surveys suggest the American left is now measurably more resistant [=
https://jasonjones.ninja/social-science-dashboard-inator/jjjp-ai-daily-da= shboard/ai-polarization.html] to developing the technology and pessimistic=
about its likely impacts [
https://www.nbcnews.com/politics/nbc-news-poll= s/poll-americans-form-views-ai-divided-role-school-everyday-life-rcna21278=
2] on their future than their right-leaning counterparts. This follows a f= amiliar pattern of US politics=2C of course=2C and yet it points to a pote= ntial political realignment with massive consequences.
People are morally and strategically justified in pushing the Democratic P= arty to reduce its dependency [
https://jacobin.com/2022/02/dems-gop-super= -pacs-pelosi-bloomberg-warren] on funding from billionaires and corporatio= ns=2C particularly in the tech sector. But this movement should decouple t=
he technologies championed by Big Tech from those corporate interests. Opt= imism about the potential beneficial uses of AI need not imply support for=
the Big Tech companies that currently dominate AI development. To view th=
e technology as inseparable from the corporations is to risk unilateral di= sarmament as AI shifts power balances throughout democracy. AI can be a le= gitimate tool for building the power of workers=2C operating government an=
d advancing the public interest=2C and it can be that even while it is exp= loited as a mechanism for oligarchs to enrich themselves and advance their=
interests.
A constructive version of DOGE could have redirected the Digital Service t=
o coordinate and advance the thousands of AI use cases [
https://www.cio.g= ov/policies-and-priorities/Executive-Order-13960-AI-Use-Case-Inventories-R= eference/] already being explored across the US government. Following the=
example of countries like Canada [
https://www.tbs-sct.canada.ca/pol/doc-= eng.aspx?id=3D32592]=2C each instance could have been required to make a d= etailed public disclosure as to how they would follow a unified set of pri= nciples for responsible use that preserves civil rights while advancing go= vernment efficiency.
Applied to different ends=2C AI could have produced celebrated success sto= ries rather than national embarrassments [
https://www.washingtonpost.com/= opinions/2025/03/21/doge-government-efficiency-federal-workers/].
A different administration might have made AI translation services widely=
available in government services to eliminate language barriers to US cit= izens=2C residents and visitors=2C instead of revoking [
https://www.vorys= =2Ecom/publication-what-president-trumps-english-only-executive-orders-mean-= for-employers-nationwide] some of the modest translation requirements prev= iously in place. AI could have been used to accelerate eligibility decisio=
ns for Social Security disability benefits by performing preliminary docum=
ent reviews=2C significantly reducing the infamous backlog of 30=2C000 Ame= ricans who die annually awaiting review. Instead=2C the deaths of people a= waiting benefits may now double [
https://www.sanders.senate.gov/wp-conten= t/uploads/SSA-DOGE-Impact-Report.pdf] due to cuts by DOGE. The technology=
could have helped speed up the ministerial work of federal immigration ju= dges=2C helping them whittle down a backlog of millions of waiting cases.=
Rather=2C the judicial systems must face this backlog amid firings [http= s://www.npr.org/2025/07/15/nx-s1-5467710/immigration-judges-are-being-fire= d-despite-backlog-of-immigration-cases] of immigration judges=2C despite t=
he backlog.
To reach these constructive outcomes=2C much needs to change. Electing lea= ders committed to leveraging AI more responsibly in government would help=
=2C but the solution has much more to do with principles and values than i=
t does technology. As historian Melvin Kranzberg said [
https://www.jstor.= org/stable/3105385?seq=3D1&cid=3Dpdf-reference#references_tab_contents]=2C=
technology is never neutral: its effects depend on the contexts it is use=
d in and the aims it is applied towards. In other words=2C the positive or=
negative valence of technology depends on the choices of the people who w= ield it.
The Trump administration=E2=80=99s plan to use AI to advance their regulat=
ory rollback is a case in point. DOGE has introduced [
https://www.washing= tonpost.com/business/2025/07/26/doge-ai-tool-cut-regulations-trump/] an=
=E2=80=9CAI Deregulation Decision Tool=E2=80=9D that it intends to use th= rough automated decision-making to eliminate about half of a catalog of ne= arly 200=2C000 federal rules . This follows similar proposals to use AI fo=
r large-scale revisions of the administrative code in Ohio [
https://www.a= xios.com/local/columbus/2024/04/29/artificial-intelligence-ai-ohio-state-a= dministrative-code-husted]=2C Virginia [
https://statescoop.com/virginia-a= gentic-gen-ai-pilot-regulations/#:~:text=3DThe%20initiative%2C%20which%20w= ill%20make=2Ctransparency%20to%20reduce%20regulatory%20burden] and the US=
Congress [
https://www.husted.senate.gov/press-releases/husted-introduces= -bill-leveraging-ai-to-increase-efficiency-within-federal-code/].
This kind of legal revision could be pursued in a nonpartisan and nonideol= ogical way=2C at least in theory. It could be tasked with removing outdate=
d rules from centuries past=2C streamlining redundant provisions and moder= nizing and aligning legal language. Such a nonpartisan=2C nonideological s= tatutory revision has been performed in Ireland [
https://en.wikipedia.org= /wiki/Statute_Law_Revision_Act_2007] -- by people=2C not AI -- and other j= urisdictions. AI is well suited to that kind of linguistic analysis at a m= assive scale and at a furious pace.
But we should never rest on assurances that AI will be deployed in this ki=
nd of objective fashion. The proponents of the Ohio=2C Virginia=2C congres= sional and DOGE efforts are explicitly ideological in their aims. They see=
=E2=80=9CAI as a force for deregulation [
https://www.wsj.com/opinion/ai-= can-be-a-force-for-deregulation-technology-government-ohio-federal-365ed0d= 4]=2C=E2=80=9D as one US senator who is a proponent put it=2C unleashing c= orporations from rules that they say constrain economic growth. In this se= tting=2C AI has no hope to be an objective analyst independently performin=
g a functional role; it is an agent of human proponents with a partisan ag= enda.
The moral of this story is that we can achieve positive outcomes for worke=
rs and the public interest as AI transforms governance=2C but it requires=
two things: electing leaders who legitimately represent and act on behalf=
of the public interest and increasing transparency in how the government=
deploys technology.
Agencies need to implement technologies under ethical frameworks=2C enforc=
ed by independent inspectors and backed by law. Public scrutiny helps bind=
present and future governments to their application in the public interes=
t and to ward against corruption.
These are not new ideas and are the very guardrails that Trump=2C Musk and=
DOGE have steamrolled over the past six months. Transparency [
https://ww= w.axios.com/2025/05/21/musk-doge-supreme-court-transparency-lawsuit] and p= rivacy [
https://cyberscoop.com/lawmakers-fear-elon-musk-doge-not-adhering= -to-privacy-rules/] requirements were avoided or ignored=2C independent ag= ency inspectors general were fired [
https://campaignlegal.org/update/sign= ificance-firing-inspectors-general-explained] and the budget dictates of C= ongress were disrupted [
https://www.cbpp.org/research/federal-budget/trum= p-rescission-proposal-builds-on-illegal-impoundments-would-undermine]. For=
months=2C it has not even been clear who is in charge [
https://www.lawfa= remedia.org/article/the-witaod-chronicles] of and accountable for DOGE=E2= =80=99s actions. Under these conditions=2C the public should be similarly=
distrustful of any executive=E2=80=99s use of AI.
We think everyone should be skeptical of today=E2=80=99s AI ecosystem and=
the influential elites that are steering it towards their own interests.=
But we should also recognize that technology is separable from the humans=
who develop it=2C wield it and profit from it=2C and that positive uses o=
f AI are both possible and achievable.

** NEW CRYPTANALYSIS OF THE FIAT-SHAMIR PROTOCOL ------------------------------------------------------------
[2025.09.09] [
https://www.schneier.com/blog/archives/2025/09/new-cryptan= alysis-of-the-fiat-shamir-protocol.html] A couple of months ago=2C a new p= aper [
https://eprint.iacr.org/2025/118] demonstrated some new attacks aga=
inst the Fiat-Shamir transformation. _Quanta_ published a good article [h= ttps://www.quantamagazine.org/computer-scientists-figure-out-how-to-prove-= lies-20250709/] that explains the results.
This is a pretty exciting paper from a theoretical perspective=2C but I do= n=E2=80=99t see it leading to any practical real-world cryptanalysis. The=
fact that there are some weird circumstances that result in Fiat-Shamir i= nsecurities isn=E2=80=99t new -- many dozens of papers have been published=
about it since 1986. What this new result does is extend this known probl=
em to slightly less weird (but still highly contrived) situations. But it= =E2=80=99s a completely different matter to extend these sorts of attacks=
to =E2=80=9Cnatural=E2=80=9D situations.
What this result does=2C though=2C is make it impossible to provide genera=
l proofs of security for Fiat-Shamir. It is the most interesting result in=
this research area=2C and demonstrates that we are still far away from fu=
lly understanding what is the exact security guarantee provided by the Fia= t-Shamir transform.

** A CYBERATTACK VICTIM NOTIFICATION FRAMEWORK ------------------------------------------------------------
[2025.09.12] [
https://www.schneier.com/blog/archives/2025/09/a-cyberatta= ck-victim-notification-framework.html] Interesting analysis [
https://secu= rityandtechnology.org/virtual-library/report/improving-private-sector-cybe= r-victim-notification-and-support/]:
When cyber incidents occur=2C victims should be notified in a timely man=
ner so they have the opportunity to assess and remediate any harm. However=
=2C providing notifications has proven a challenge across industry.
When making notifications=2C companies often do not know the true identi=
ty of victims and may only have a single email address through which to pr= ovide the notification. Victims often do not trust these notifications=2C=
as cyber criminals often use the pretext of an account compromise as a ph= ishing lure.
[...]
This report explores the challenges associated with developing the nativ=
e-notification concept and lays out a roadmap for overcoming them. It also=
examines other opportunities for more narrow changes that could both incr= ease the likelihood that victims will both receive and trust notifications=
and be able to access support resources.
The report concludes with three main recommendations for cloud service p=
roviders (CSPs) and other stakeholders:
1. Improve existing notification processes and develop best practic=
es for industry.
2. Support the development of =E2=80=9Cmiddleware=E2=80=9D necessar=
y to share notifications with victims privately=2C securely=2C and across=
multiple platforms including through native notifications.
3. Improve support for victims following notification.
While further work remains to be done to develop and evaluate the CSRB=
=E2=80=99s proposed native notification capability=2C much progress can be=
made by implementing better notification and support practices by cloud s= ervice providers and other stakeholders in the near term.

<p>In this work=2C we perform the first security analysis of AIOps solutio= ns=2C showing that=2C once again=2C AI-driven automation comes with a prof= ound security cost. We demonstrate that adversaries can manipulate system=
telemetry to mislead AIOps agents into taking actions that compromise the=

agent behavior through a form of adversarial reward-hacking; plausible bu=

<p>To counter this threat=2C we propose AIOpsShield=2C a defense mechanism=
that sanitizes telemetry data by exploiting its structured nature and the=

<p>This will be critical in a world where <a href=3D"
https://spectrum.ieee= =2Eorg/tag/ai-agents">AI agents</a> don=E2=80=99t just answer our questions=
but act on our behalf. These agents may execute financial transactions=2C=

<h3 style=3D"font-size:110%;font-weight:bold">What Is Data Integrity?</h3>
<p>In information systems=2C integrity is the guarantee that data will not=
be modified without authorization=2C and that all transformations are ver= ifiable throughout the data=E2=80=99s life cycle. While availability ensur=
es that systems are running and confidentiality prevents unauthorized acce= ss=2C integrity focuses on whether information is accurate=2C unaltered=2C=
and consistent across systems and over time.</p>
<p>It=E2=80=99s a new idea. The undo button=2C which prevents accidental d=
ata loss=2C is an integrity feature. So is the reboot process=2C which ret= urns a computer to a known good state. Checksums are an integrity feature;=
so are verifications of network transmission. Without integrity=2C securi=

https://spectrum.ieee.org/tag/amplifiers">amplifiers</a> of risk= =2E</p>
<p>All <a href=3D"
https://spectrum.ieee.org/tag/it-systems">IT systems</a>=
require some form of data integrity=2C but the need for it is especially=
pronounced in two areas today. First: <a href=3D"
https://spectrum.ieee.or= g/tag/internet-of-things">Internet of Things</a> devices interact directly=
with the physical world=2C so corrupted input or output can result in rea= l-world harm. Second: AI systems are only as good as the integrity of the=
data they=E2=80=99re trained on=2C and the integrity of their decision-ma= king processes. If that foundation is shaky=2C the results will be too.</p=
<p>Integrity manifests in four key areas. The first=2C <em>input integrity= =2C</em> concerns the quality and authenticity of data entering a system.=
When this fails=2C consequences can be severe. In 2021=2C <a href=3D"http= s://engineering.fb.com/2021/10/05/networking-traffic/outage-details/">Face= book=E2=80=99s global outage</a> was triggered by a single mistaken comman=
d -- an input error missed by automated systems. Protecting input integrit=
y requires robust <a href=3D"
https://spectrum.ieee.org/tag/authentication"= >authentication</a> of data sources=2C cryptographic signing of sensor dat= a=2C and diversity in input channels for cross-validation.</p>
<p>The second issue is <em>processing integrity=2C</em> which ensures that=
systems transform inputs into outputs correctly. In 2003=2C the <a href= =3D"
https://www.nerc.com/pa/rrm/ea/Documents/August_2003_Blackout_Final_Re= port.pdf">U.S.-Canada blackout</a> affected 55 million people when a contr= ol-room process failed to refresh properly=2C resulting in damages exceedi=
ng US $6 billion. Safeguarding processing integrity means formally verifyi=
ng algorithms=2C cryptographically protecting models=2C and monitoring sys= tems for anomalous behavior.</p>
<p><em>Storage integrity</em> covers the correctness of information as it= =E2=80=99s stored and communicated. In 2023=2C the Federal Aviation Admini= stration was <a href=3D"
https://www.thestack.technology/faa-outage-cause-n= otam-database-file-not-cyber/">forced to halt</a> all U.S. departing fligh=
ts because of a corrupted database file. Addressing this risk requires cry= ptographic approaches that make any modification computationally infeasibl=
e without detection=2C distributed storage systems to prevent single point=
s of failure=2C and rigorous backup procedures.</p>
<p>Finally=2C <em>contextual integrity</em> addresses the appropriate flow=
of information according to the norms of its larger context. It=E2=80=99s=
not enough for data to be accurate; it must also be used in ways that res= pect expectations and boundaries. For example=2C if a smart speaker listen=
s in on casual family conversations and uses the data to build advertising=
profiles=2C that action would violate the expected boundaries of <a href= =3D"
https://spectrum.ieee.org/tag/data-collection">data collection</a>. Pr= eserving contextual integrity requires clear data-governance policies=2C p= rinciples that limit the use of data to its intended purposes=2C and mecha= nisms for enforcing information-flow constraints.</p>
<p>As AI systems increasingly make critical decisions with reduced human o= versight=2C all these dimensions of integrity become critical.</p>
<h3 style=3D"font-size:110%;font-weight:bold">The Need for Integrity in We=

<h3 style=3D"font-size:110%;font-weight:bold">Why Data Integrity Matters i=
n AI</h3>
<p>For AI systems=2C integrity is crucial in four domains. The first is de= cision quality. With AI increasingly contributing to decision-making in <a=
href=3D"
https://spectrum.ieee.org/tag/health-care">health care</a>=2C jus= tice=2C and finance=2C the integrity of both data and models=E2=80=99 acti=
ons directly impact human welfare. Accountability is the second domain. Un= derstanding the causes of failures requires reliable logging=2C audit trai= ls=2C and system records.</p>
<p>The third domain is the security relationships between components. Many=
authentication systems rely on the integrity of identity information and=
cryptographic keys. If these elements are compromised=2C malicious agents=
could impersonate trusted systems=2C potentially creating cascading failu=
res as <a href=3D"
https://spectrum.ieee.org/tag/agentic-ai">AI agents</a>=
interact and make decisions based on corrupted credentials.</p>
<p>Finally=2C integrity matters in our public definitions of safety. Gover= nments worldwide are introducing <a href=3D"
https://spectrum.ieee.org/ai-r= egulation-worldwide">rules for AI</a> that focus on data accuracy=2C trans= parent algorithms=2C and verifiable claims about system behavior. Integrit=
y provides the basis for meeting these legal obligations.</p>
<p>The importance of integrity only grows as AI systems are entrusted with=
more critical applications and operate with less human oversight. While p= eople can sometimes detect integrity lapses=2C <a href=3D"
https://spectrum= =2Eieee.org/tag/autonomous-systems">autonomous systems</a> may not only miss=
warning signs -- they may exponentially increase the severity of breaches=
=2E Without assurances of integrity=2C organizations will not trust AI syste= ms for important tasks=2C and we won=E2=80=99t realize the full potential=
of AI.</p>
<h3 style=3D"font-size:110%;font-weight:bold">How to Build AI Systems With=
Integrity</h3>
<p>Imagine an AI system as a home we=E2=80=99re building together. The int= egrity of this home doesn=E2=80=99t rest on a single security feature but=
on the thoughtful integration of many elements: solid foundations=2C well= -constructed walls=2C clear pathways between rooms=2C and shared agreement=
s about how spaces will be used.</p>
<p>We begin by laying the cornerstone: <a href=3D"
https://spectrum.ieee.or= g/pioneers-web-cryptography-future-authentication">cryptographic verificat= ion</a>. Digital signatures ensure that data lineage is traceable=2C much=
like a title deed proves ownership. Decentralized identifiers act as digi=
tal <a href=3D"
https://spectrum.ieee.org/tag/passports">passports</a>=2C a= llowing components to prove identity independently. When the front door of=
our AI home recognizes visitors through their own keys rather than throug=
h a vulnerable central doorman=2C we create resilience in the architecture=
of trust.</p>
<p>Formal verification methods enable us to mathematically prove the struc= tural integrity of critical components=2C ensuring that systems can withst=
and pressures placed upon them -- especially in high-stakes domains where=
lives may depend on an AI=E2=80=99s decision.</p>
<p>Just as a well-designed home creates separate spaces=2C trustworthy AI=
systems are built with thoughtful compartmentalization. We don=E2=80=99t=
rely on a single barrier but rather layer them to limit how problems in o=
ne area might affect others. Just as a <a href=3D"
https://spectrum.ieee.or= g/tag/kitchen">kitchen</a> fire is contained by fire doors and independent=
smoke alarms=2C training data is separated from the AI=E2=80=99s inferenc=
es and output to limit the impact of any single failure or breach.</p>
<p>Throughout this AI home=2C we build transparency into the design: The e= quivalent of large windows that allow light into every corner is clear pat= hways from input to output. We install monitoring systems that continuousl=
y check for weaknesses=2C alerting us before small issues become catastrop=
hic failures.</p>
<p>But a home isn=E2=80=99t just a physical structure=2C it=E2=80=99s also=
the agreements we make about how to live within it. Our governance framew= orks act as these shared understandings. Before welcoming new residents=2C=
we provide them with certification standards. Just as landlords conduct c= redit checks=2C we conduct integrity assessments to evaluate newcomers. An=
d we strive to be good neighbors=2C aligning our community agreements with=
broader societal expectations. Perhaps most important=2C we recognize tha=
t our AI home will shelter diverse individuals with varying needs. Our gov= ernance structures must reflect this diversity=2C bringing many stakeholde=
rs to the table. A truly trustworthy system cannot be designed only for it=
s builders but must serve anyone authorized to eventually call it home.</p=
<p>That=E2=80=99s how we=E2=80=99ll create AI systems worthy of trust: not=
by blindly believing in their perfection but because we=E2=80=99ve intent= ionally designed them with integrity controls at every level.</p>
<h3 style=3D"font-size:110%;font-weight:bold">A Challenge of Language</h3>
<p>Unlike other properties of security=2C like =E2=80=9Cavailable=E2=80=9D=
or =E2=80=9Cprivate=2C=E2=80=9D we don=E2=80=99t have a common adjective=
form for =E2=80=9Cintegrity.=E2=80=9D This makes it hard to talk about it=
=2E It turns out that there is a word in English: =E2=80=9Cintegrous.=E2=80= =9D The Oxford English Dictionary recorded the word used in the mid-1600s=
but now <a href=3D"
https://www.oed.com/dictionary/integrous_adj?tab=3Dfac= tsheet&tl=3Dtrue#210671">declares it obsolete</a>.</p>
<p>We believe that the word needs to be revived. We need the ability to de= scribe a system with integrity. We must be able to talk about integrous sy= stems design.</p>
<h3 style=3D"font-size:110%;font-weight:bold">The Road Ahead</h3>
<p>Ensuring integrity in AI presents formidable challenges. As models grow=
larger and more complex=2C maintaining integrity without sacrificing perf= ormance becomes difficult. Integrity controls often require computational=
resources that can slow systems down -- particularly challenging for real= -time applications. Another concern is that <a href=3D"

https://spectrum.ieee.org/tag/libraries">libraries</a>=2C frameworks=
=2C and services -- presents a large attack surface.</p>
<p>Beyond technology=2C integrity depends heavily on social factors. Compa= nies often prioritize speed to market over robust integrity controls. Deve= lopment teams may lack specialized knowledge for implementing these contro= ls=2C and may find it particularly difficult to integrate them into legacy=
systems. And while some governments have begun establishing regulations f=
or aspects of AI=2C we need worldwide alignment on governance for AI integ= rity.</p>
<p>Addressing these challenges requires sustained research into verifying=
and enforcing integrity=2C as well as recovering from breaches. Priority=
areas include <a href=3D"

<p>As AI systems become more powerful and pervasive=2C the stakes for inte= grity have never been higher. We are entering an era where machine-to-mach=

<p>The good news is that the tools for building systems with integrity alr= eady exist. What=E2=80=99s needed is a shift in mind-set: from treating in= tegrity as an afterthought to accepting that it=E2=80=99s the core organiz=

<p>The next era of technology will be defined not by what AI can do=2C but=
by whether we can trust it to know or especially to do what=E2=80=99s rig=

<p><b>Abstract:</b> The growing integration of LLMs into applications has=
introduced new security risks=2C notably known as Promptware -- malicious=
ly engineered prompts designed to manipulate LLMs to compromise the CIA tr=
iad of these applications. While prior research warned about a potential s= hift in the threat landscape for LLM-powered applications=2C the risk pose=
d by Promptware is frequently perceived as low. In this paper=2C we invest= igate the risk Promptware poses to users of Gemini-powered assistants (web=
application=2C mobile application=2C and Google Assistant). We propose a=
novel Threat Analysis and Risk Assessment (TARA) framework to assess Prom= ptware risks for end users. Our analysis focuses on a new variant of Promp= tware called Targeted Promptware Attacks=2C which leverage indirect prompt=
injection via common user interactions such as emails=2C calendar invitat= ions=2C and shared documents. We demonstrate 14 attack scenarios applied a= gainst Gemini-powered assistants across five identified threat classes: Sh= ort-term Context Poisoning=2C Permanent Memory Poisoning=2C Tool Misuse=2C=
Automatic Agent Invocation=2C and Automatic App Invocation. These attacks=
highlight both digital and physical consequences=2C including spamming=2C=
phishing=2C disinformation campaigns=2C data exfiltration=2C unapproved u=
ser video streaming=2C and control of home automation devices. We reveal P= romptware=E2=80=99s potential for on-device lateral movement=2C escaping t=
he boundaries of the LLM-powered application=2C to trigger malicious actio=
ns using a device=E2=80=99s applications. Our TARA reveals that 73% of the=
analyzed threats pose High-Critical risk to end users. We discuss mitigat= ions and reassess the risk (in response to deployed mitigations) and show=
that the risk could be reduced significantly to Very Low-Medium. We discl= osed our findings to Google=2C which deployed dedicated mitigations.</p></= blockquote>

<p><i>Rewiring Democracy</i> looks beyond common tropes like deepfakes to=
examine how AI technologies will affect democracy in five broad areas: po= litics=2C legislating=2C administration=2C the judiciary=2C and citizenshi=
p. There is a lot to unpack here=2C both positive and negative. We do talk=
about AI=E2=80=99s possible role in both democratic backsliding or restor=
ing democracies=2C but the fundamental focus of the book is on present and=
future uses of AIs within functioning democracies. (And there is a lot go=
ing on=2C in both national and local governments around the world.) And=2C=
yes=2C we talk about AI-driven propaganda and artificial conversation.</p=
<p>Some of what we write about is happening now=2C but much of what we wri=
te about is speculation. In general=2C we take an optimistic view of AI=E2= =80=99s capabilities. Not necessarily because we buy all the hype=2C but b= ecause a little optimism is necessary to discuss possible societal changes=
due to the technologies -- and what=E2=80=99s really interesting are the=
second-order effects of the technologies. Unless you can imagine an array=
of possible futures=2C you won=E2=80=99t be able to steer towards the fut= ures you want. We end on the need for <a href=3D"

<p>Honestly=2C this was a challenging book to write through the US preside= ntial campaign of 2024=2C and then the first few months of the second Trum=
p administration. I think we did a good job of acknowledging the realities=
of what is happening in the US without unduly focusing on it.</p>

<p>But we should never rest on assurances that AI will be deployed in this=

<p>This is a pretty exciting paper from a theoretical perspective=2C but I=

<p>What this result does=2C though=2C is make it impossible to provide gen= eral proofs of security for Fiat-Shamir. It is the most interesting result=

<blockquote><p>When cyber incidents occur=2C victims should be notified in=
a timely manner so they have the opportunity to assess and remediate any=
harm. However=2C providing notifications has proven a challenge across in= dustry.</p>
<p>When making notifications=2C companies often do not know the true ident=
ity of victims and may only have a single email address through which to p= rovide the notification. Victims often do not trust these notifications=2C=
as cyber criminals often use the pretext of an account compromise as a ph= ishing lure.</p>
<p>[...]</p>
<p>This report explores the challenges associated with developing the nati= ve-notification concept and lays out a roadmap for overcoming them. It als=
o examines other opportunities for more narrow changes that could both inc= rease the likelihood that victims will both receive and trust notification=
s and be able to access support resources.</p>
<p>The report concludes with three main recommendations for cloud service=
providers (CSPs) and other stakeholders:</p>
<ol><li>Improve existing notification processes and develop best practices=
for industry.
</li><li>Support the development of =E2=80=9Cmiddleware=E2=80=9D necessary=
to share notifications with victims privately=2C securely=2C and across m= ultiple platforms including through native notifications.
</li><li>Improve support for victims following notification.</li></ol>
<p>While further work remains to be done to develop and evaluate the CSRB= =E2=80=99s proposed native notification capability=2C much progress can be=
made by implementing better notification and support practices by cloud s= ervice providers and other stakeholders in the near term.</p></blockquote>
