On January 9, 2024, the official U.S. Securities and Exchange Commission Twitter account announced that the SEC had approved Bitcoin ETFs. Bitcoin’s price spiked roughly 10 percent in minutes. The announcement was fake — attackers had SIM-swapped the phone number linked to the SEC’s account, intercepted the verification code, and posted on the SEC’s behalf. The actual approval came the next day. The SEC is not a small business. It has a legal team, a security team, and a public-facing communications infrastructure.
