A British national extradited to the US has pleaded guilty in New York to a role in one of the biggest hacks in social media history.
The July 2020 Twitter hack affected over 130 accounts including those of Barack Obama and Joe Biden.
Joseph James O'Connor, 23, known as PlugwalkJoe, pleaded guilty to hacking charges carrying a total maximum sentence of over 70 years in prison.
The hacking was part of a large-scale Bitcoin scam.
O'Connor, who was extradited from Spain, hijacked numerous Twitter accounts and sent out tweets asking followers to send Bitcoin to an account, promising to double their money.
