• Postmortem of the Xubuntu.org download site compromise

    From LWN.net@86:200/23 to All on Thu Nov 20 06:40:07 2025

    In mid-October, the Xubuntu
    download site was compromised and had directed users to a malicious
    zip file instead of the Torrent file that users expected. Elizabeth
    K. Joseph has published
    a postmortem of the incident, along with plans to avoid such a breach
    in the future:

    To be perfectly clear: this only impacted our website, and the torrent
    links provided there.

    If you downloaded or opened a file named "Xubuntu-Safe-Download.zip"
    from the Xubuntu downloads page during this period, you should assume
    it was malicious. We strongly recommend scanning your computer with a
    trusted antivirus or anti-malware solution and deleting the file
    immediately.

    Nothing on cdimages.ubuntu.com or any of the other official Ubuntu
    repositories was impacted, and our mirrors remained safe as long as
    they were also mirroring from official resources.

    None of the build systems, packages, or other components of Xubuntu
    itself were impacted.
