Taylor Swift‘s Twitter and Instagram accounts were hacked Tuesday, with the perpetrators reportedly sending out a handful of tweets to the pop star’s over 51 million followers that were quickly deleted, according to The Verge.

Swift is the owner of the fourth largest Twitter account, making this breach one of the biggest in Twitter’s history. The damage, however, was minimal, with the offending tweets simply suggesting Swift’s fans follow the “@lizzard” account and a user named “@veriuser,” who claimed to be the leader of the responsible hacking group, Lizard Squad (the latter account has been suspended). Similarly, an Instagram photo sent out to Swift’s over 20 million followers urged users to follow another user supposedly involved in the Twitter hack.

Twitter has come under fire over the past few years following a number of major account hacks, from the Associated Press to musicians like the Flaming Lips, No Doubt, Rise Against and Nicole Scherzinger. In response to the attacks, Twitter recently bolstered their security by implementing a two-factor authentication process.

Swift addressed privacy concerns in her Rolling Stone cover story last September, though they specifically pertained to possible leaks of 1989‘s first single, “Shake It Off” and its video. When asked who might bug her office where the then-unreleased song and clip were being stored, she replied hypothetically: “The janitor who’s being paid by TMZ. This is gonna sound like I’m a crazy person — but we don’t even know. I have to stop myself from thinking about how many aspects of technology I don’t understand.”
