Twitter accounts belonging to Joe Biden, Bill Gates, Elon Musk and Apple, among others, were compromised on Wednesday and posted tweets that promote a cryptocurrency scam.Additionally, accounts of former President Barack Obama, Kanye West, Warren Buffett, Jeff Bezos and Mike Bloomberg, also posted similar tweets soliciting donations via Bitcoin.“Everyone is asking me to give back, and now is the time,” Gates’ tweet said. That message promised to double all payments made to a Bitcoin address for 30 minutes after it was posted.A spokesperson for Twitter said the company is looking into the issue. “We can confirm that this tweet was not sent by Bill Gates,” a spokesperson for Gates told CNN Business. “This appears to be part of a larger issue that Twitter is facing. Twitter is aware and working to restore the account.”Meanwhile, Uber later tweeted, “Like many others, our @Uber account was hit by a scammer today. The tweet has been deleted and we’re working directly with @Twitter to figure out what happened.”This is a developing story.
