#Meta's #AI feature let attackers hijack Instagram accounts for days with nothing but a username. It was being A/B tested on a slice of users, and if you were in the test, you couldn't turn it off. Among the casualties: the official Obama White House account.

Meta has since patched it. There was no public acknowledgment.
