At the time of the July 15 attack, Twitter had no chief information security officer and suffered from poor internal security controls, the report concluded — calling for additional cybersecurity regulation of major tech platforms. Twitter didn’t immediately respond to a request for comment.
The high-profile hack saw several celebrity accounts taken over by a bitcoin scam that promised victims a 100% return on their investments. In addition to Obama and Musk, the hackers were able to take over accounts belonging to Joe Biden, Kim Kardashian West, Uber and Apple, among others. As one of the nation’s top regulators of virtual currency, the Department launched its investigation into the attack shortly after it came to light, and is based on subpoenas, witness interviews and documentary records.
“Since switching to remote working, VPN problems were common at Twitter,” the report said. “The Hackers then tried to direct the employee to a phishing website that looked identical to the legitimate Twitter VPN website and was hosted by a similarly named domain.”
The hackers used the fake website to steal the employee’s login credentials, the report said, then typed the stolen information into Twitter’s real administrative website, prompting a multi-factor authentication challenge. The hackers then asked for the security code over the phone to gain access to Twitter’s back end, according to the report. The hackers repeated the process for other employees.
Ultimately, the scheme resulted in a bitcoin scam that was spread widely to millions of users, and resulted in a haul of $118,000 worth of bitcoin, the report said.
