Joseph O’Conner, also known by his online handle PlugWalkJoe, was arrested Wednesday by the Spanish National Police in Estepona, Spain, at the request of the Federal Bureau of Investigation (FBI). He was charged with multiple counts of conspiracy and intentionally accessing a computer without authorization.
The Twitter hack compromised the accounts of top cryptocurrency exchanges, and prominent crypto Twitter accounts (including CoinDesk), before moving on to mainstream accounts including those of Elon Musk, Warren Buffett, Kanye West, Joe Biden and former President Barack Obama.
The accounts all tweeted a bitcoin scam, promising to double senders' bitcoin if they sent them to a specific address.
O’Conner is the fourth co-conspirator to be arrested in connection with the hack.
