Hello,
On 14 January 2020, staff at the Wikimedia Foundation discovered that a data file exported from the Wikimedia Phabricator installation, our engineering task and ticket tracking system, had been made publicly available. The file was leaked accidentally; there was no intrusion. We have no evidence that it was ever viewed or accessed. The Foundation's Security team immediately began investigating the incident and removing the related files. The data dump included limited non-public information such as private tickets, login access tokens, and the second factor of the two-factor authentication keys for Phabricator accounts. Passwords and full login information for Phabricator were not affected -- that information is stored in another, unaffected system. The Security team has investigated and assesses that there is no known impact from this incident. However, out of an abundance of caution, we are resetting all Two-Factor Authentication keys for Phabricator and invalidating the exposed login access tokens. Additionally, we continue to encourage people to engage in online security best practices, such as keeping your software updated and resetting your passwords regularly. The Foundation will continue to investigate this incident and take steps to prevent it from occurring again in the future. In the meantime, Phabricator is online and functioning normally. We regret any inconvenience this may have caused and will provide updates if we learn of any further impact. Respectfully, David Sharpe Senior Information Security Analyst Wikimedia Foundation _______________________________________________ Wikimedia-l mailing list, guidelines at: https://meta.wikimedia.org/wiki/Mailing_lists/Guidelines and https://meta.wikimedia.org/wiki/Wikimedia-l New messages to: Wikimedia-l@lists.wikimedia.org Unsubscribe: https://lists.wikimedia.org/mailman/listinfo/wikimedia-l, <mailto:wikimedia-l-requ...@lists.wikimedia.org?subject=unsubscribe>
