As Twitter grapples with the worst security breach in its 14-year history, it must now uncover whether its employees were victims of sophisticated phishing schemes or if they deliberately allowed hackers to access high-profile accounts.
On Wednesday, some of the world’s most prominent names, including former president Barack Obama and Democratic candidate and his former vice president Joe Biden, along with Bill Gates, Elon Musk and Warren Buffett, had their Twitter accounts post invitations for an apparent Bitcoin scam. Twitter reacted by blocking further posts from all verified accounts on the service and said it had detected “a coordinated social engineering attack by people who successfully targeted some of our employees with access to internal systems and tools.”
The company’s explanation has ignited speculation over the identity of the perpetrators and what they were actually targeting in the attack. The scale of the endeavor and its timing — months before the November U.S. elections — have prompted some cybersecurity experts to theorize that the attack masked a more nefarious campaign to seize sensitive data.
In its investigation of the incident, Twitter will now likely focus on employee logs, email and phone records. At question will be any failures in authentication processes that might have allowed hackers to hijack verified accounts, and also what other information, such as direct messages, might have been compromised in the breach. The Bitcoin wallets promoted in the tweets collected around $120,000 in cryptocurrency.
Twitter shares were down about 3% Thursday morning in New York
