The Ubuntu forums have been hacked, and data belonging to over 2 Million users have been compromised, Canonical just announced. The company failed to apply a patch to secure its users’ data. The attackers were able to inject formatted SQL to the Forums database on the forums database servers, which gave them access to read from any table. Users’ data include their IP addresses, usernames, and email addresses, according to the company. The breach did not affect the Ubuntu operating system, or it was not due to a weakness in the OS.
