Ubuntu infrastructure down for over 24 hours after sustained DDoS attack claimed by pro-Iran hacktivists

Tags Security · Infrastructure · Open source

Canonical's Ubuntu web infrastructure has been offline for more than 24 hours as of May 1 after a sustained DDoS attack claimed by hacktivists sympathetic to the Iranian government on Telegram. The outage, which began Thursday, blocks access to Ubuntu's security API, Snap Store, Launchpad, mailing lists, and canonical.com — preventing users from installing or applying security updates. The attack uses the Beam DDoS-for-hire 'stressor' service. The outage coincides with the public disclosure of a critical Linux root-privilege vulnerability called 'CopyFail', compounding the risk. Canonical confirmed a 'sustained, cross-border attack' on its status page. For IT and security professionals, the simultaneous infrastructure takedown and critical vulnerability disclosure created a worst-case scenario where millions of Linux administrators could not patch their systems.
