Several Twitter accounts were hacked in order to deceive followers on bitcoin. Joe Biden, Kanye West and Barack Obama were some of those who had their accounts hacked.

Attempted fraud

From the accounts, the post was published where it is claimed that you have half an hour to send the equivalent of 1,000 dollars in the cryptocurrency bitcoin, and then get twice as much back.

"This seems to be the worst hack of a major social media platform to date," said Dimitri Alperovitch, co-founder of cybersecurity company Crowdstrike.

May have had help on the inside

The FBI will now investigate what happened.

Twitter believes that the hackers have used selected Twitter employees, who have access to the internal system.
