Elon Musk, Bill Gates and Democratic Presidential candidate Joe Biden were all hit with a similar apparent breach of security.
All of their Twitter accounts posted messages urging people to send Bitcoins – a kind of cryptocurrency – to the same address.
Microsoft founder Bill Gate’s account posted: “Everyone is asking me to give back, and now is the time.
Other people targeted in the apparent scam include Kanye West, Apple and Uber.
A spokesperson for Gates said the hack “appears to be part of a larger issue Twitter is facing”.
