As Twitter Inc 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 July 15, some of the world’s most prominent people, including former US president Barack Obama and Democratic US presidential candidate 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”.
