A series of high-profile Twitter accounts were accessed in quick succession Wednesday, including those of former President Barack Obama and former Vice President Joe Biden, the current leading candidate for the Democratic nomination for president.
Additionally, the accounts of rapper Kanye West and billionaires Mike Bloomberg, Elon Musk, Warren Buffett and Jeff Bezos were also compromised, along with the corporate accounts for Apple, Uber and Cash App.
“I am giving back to the community,” the message posted on Biden’s account said. “All Bitcoin sent to the address below will be sent back doubled! If you sent $1,000, I will send back $2,000. Only doing this for 30 minutes.”
A variation of this message, with a Bitcoin wallet address, was posted on each affected account after 5 p.m. Wednesday.
“Twitter locked down the account immediately following the breach and removed the related tweet. We remain in touch with Twitter on the matter,” a spokesperson for Biden’s campaign said in a statement.
A spokesperson for Twitter said the company was aware of the issue but did not immediately have a statement. Twitter tweeted from its corporate account that it was investigating and “taking steps to fix it.”
Around 6 p.m. on Wednesday, many verified Twitter accounts were prohibited from tweeting, perhaps an attempt to clamp down on the high-profile ones affected by the hack. Twitter did not immediately respond to a request for comment about what happened.
Those verified accounts were able to still retweet and like posts.
Twitter’s support account, also a verified account, managed to post that users “may be unable to tweet or reset your password” while they are working on the incident.
A spokesperson for Obama declined to comment on the breach.
