The widespread hacking campaign that relied on simply asking Meta AI’s chatbot to take over a victim’s Instagram account appears to have continued even after the company said the issue had been resolved. Meanwhile, the company has been scrambling to secure the targeted accounts and alert victims.

Over the weekend, hackers claimed to be exploiting Meta’s AI support chatbot to take over several high-profile Instagram accounts. At the same time, a large number of people complained on social media that their Instagram accounts had been hacked, some of them with unique short user profile handles.

TechCrunch has seen examples of allegedly hacked handles featuring common forenames or names of countries, which can be then re-sold almost as collectibles in a gray market for so-called “OG handles.” Other victims of the hacking spree appeared to be the dormant Obama White House account (which Meta disputed), and the account of the U.S. Space Force’s chief master sergeant John Bentivegna.

These attacks were so simple that calling them hacks may be giving the people behind them too much credit, while at the same time not putting enough blame on Meta for not preventing rudimentary attacks from hijacking people’s accounts.
