Mr. O’Connor has been charged in a California federal court with several counts of computer hacking related to the Twitter attack. He is also charged with intrusions related to account takeovers of TikTok and Snapchat users, according to court documents, and is charged with cyberstalking a juvenile.
Joseph O’Connor was arrested at the request of U.S. law enforcement, the Justice Department said. He is the fourth person to be charged in connection with the July 2020 hack, which hijacked high-profile Twitter accounts to post messages that solicited donations to a bitcoin wallet for causes such as Covid-19 relief efforts. Federal prosecutors have said the pleas for donations were a scam.
The attack on Twitter allowed hackers to take over an array of accounts—others included were those of Kanye West, Barack Obama, Elon Musk, Twitter Chief Executive Jack Dorsey and Apple Inc .
The disruption, coming just a few months before a presidential election, prompted national security concerns among some U.S. officials due to the platform’s role in public discourse, international affairs and government messaging. Twitter declined to comment on the arrest.
