A Tennessee man pleaded guilty Friday to hacking the U.S. Supreme Court’s electronic filing system on 25 separate days in 2023, using stolen credentials to access and publicize personal records belonging to another user. Nicholas Moore, 24, of Springfield, Tennessee, admitted in federal court that he also breached computer systems at AmeriCorps and the Department of Veterans Affairs.

Moore’s guilty plea covers unauthorized intrusions into three separate federal computer systems, all carried out using stolen credentials and publicized on a social media account he operated under the handle “@ihackedthegovernment.”

Nicholas Moore, 24, of Springfield, Tennessee, pleaded guilty Friday in federal court to hacking the U.S. Supreme Court’s electronic filing system on 25 separate days in 2023, according to court records. He also admitted to breaching computer systems at AmeriCorps and the Department of Veterans Affairs.

Moore used stolen credentials to gain access to the Supreme Court’s filing system throughout 2023, a court filing said. He accessed personal records belonging to the individual whose credentials he had stolen, then posted identifying information about that person on an Instagram account he operated under the handle “@ihackedthegovernment.”

The same Instagram account was used to publish screenshots of personal information Moore allegedly obtained from the other two federal systems. He used stolen credentials to access a user’s records from AmeriCorps’ computer servers and to enter a U.S. Marine Corps veteran’s account on the Department of Veterans Affairs’ MyHealtheVet platform, according to the filing.

Moore pleaded guilty to one misdemeanor count of computer fraud. The charge carries a maximum prison sentence of one year. U.S. Attorney Jeanine Pirro’s office filed charges against Moore the week before Friday’s plea.

U.S. District Judge Beryl Howell in Washington, D.C., is scheduled to sentence Moore on April 17.
