The Twitter accounts of Kanye West, Kim Kardashian and Barack Obama were among those hacked in what appeared to be a major cryptocurrency scam.
Official accounts on the same social media platform, including those for Joe Biden, Apple, Uber and billionaires Elon Musk, Jeff Bezos and Bill Gates, were also targeted.
They were simultaneously hacked on Wednesday evening and a scammers’ message posted encouraging users to send 1,000 dollars (£794) to a Bitcoin address.
In return, users were promised that their money will be doubled and returned to them.
A post on Tesla CEO Mr Musk’s account read: “I’m feeling generous because of Covid-19. I’ll double any BTC payment sent to my BTC address for the next hour.”
The tweet asked for Bitcoin and promised to “double all payments” sent to an address.
This was the beginning of a wave of takeovers of high-profile Twitter accounts, including Apple, Uber, Amazon CEO Mr Bezos and Microsoft founder Mr Gates.
Most of the tweets were deleted within a number of minutes, but many had been retweeted thousands of times.
