On January 9, 2024, a now-deleted tweet from @SECGov, the X account of the U.S. Securities and Exchange Commission, declared that the SEC had granted "approval for Bitcoin ETFs for listing on all registered national securities exchanges," causing the price of Bitcoin to jump by more than $1,000. The SEC, however, had done no such thing. As SEC Chair Gary Gensler tweeted minutes later, the SEC's X account had been hacked; the fraudulent tweet was posted as part of a scheme to manipulate Bitcoin prices.
The hacker responsible for that scheme, according to the FBI, is Eric Council Jr., a 25-year-old Alabama man who was arrested earlier today under allegations of working with co-conspirators to take unauthorized control of the SEC X account with a SIM swap (via The Verge).
