OAKLAND, Calif. — A Florida teenager was arrested early Friday in connection with the recent high-profile hack of 130 Twitter accounts, including the accounts of celebrities like former Vice President Joseph R. Biden Jr. and the Silicon Valley mogul Elon Musk.
Graham Ivan Clark, 17, was the “mastermind,” state officials said, of a hack that turned into an embarrassment for Twitter and called into question the security provided by a range of tech companies.
Federal authorities were already tracking Mr. Clark before the Twitter hack. In April, the Secret Service seized over $700,000 worth of Bitcoin from him, according to legal documents. The Tampa youth faces 30 felony charges, including fraud, and is being charged as an adult.
The Twitter hack began on July 15 as an effort to steal and sell unusual user names. It quickly escalated, as the hackers took over accounts belonging to cryptocurrency companies and celebrities. The scheme netted Bitcoin worth more than $180,000.
