"The official Ubuntu forums had been hacked on three different occasions -- in July 2013, in July 2016, and December 2016. Hackers stole the details of 1.82 million users in the July 2013 incident, the data of two million users in July 2016, and the forum was only defaced in the third incident.
A malicious Ubuntu package containing a cryptocurrency miner was also found on the official Ubuntu Store in May 2018."
