SEC’s X account fell victim to SIM swap attack

The US Securities and Exchange Commission admitted that the two-factor authentication on its X account had been disabled since July 2023.

The SEC’s official X account was compromised earlier this month. An unauthorized person was able to not only access the account itself, but made a fake post announcing the approval of spot bitcoin ETFs.

The post was left up on the account for roughly 15 minutes before Chair Gary Gensler took to his own account to announce that the SEC’s had been compromised.

In a follow up statement detailing what happened, the SEC said that X support asked the regulatory agency to disable the multi-factor authentication after the agency had difficulty accessing the account.

“MFA remained disabled until staff re-enabled it after the account was compromised on Jan. 9. MFA currently is enabled for all SEC social media accounts that offer it,” the statement said.

The hacker was able to access the account through a SIM swap, which is when a phone number is transferred to another device without authorization.

“Access to the phone number occurred via the telecom carrier, not via SEC systems. SEC staff have not identified any evidence that the unauthorized party gained access to SEC systems, data, devices or other social media accounts,” the SEC said.

The regulatory body is working with the Federal Bureau of Investigations, Homeland Security, the US Department of Justice and its own Division of Enforcement to track down the attacker. The agency previously disclosed that the FBI and Homeland Security’s cybersecurity department were involved in the investigation.

“Among other things, law enforcement is currently investigating how the unauthorized party got the carrier to change the SIM for the account and how the party knew which phone number was associated with the account,” the statement continued.
