The FBI and the U.S. Secret Service on Dec. 14 arrested an alleged hacker, who was indicted with two others for a massive cyberattack that included JPMorgan Chase & Co., at John F. Kennedy International Airport in New York.

Joshua Samuel Aaron — a U.S. citizen who had been residing in Moscow — allegedly hacked into the networks of dozens of American companies, which led to the largest ever theft of personal information from U.S. financial institutions, U.S. Attorney Preet Bharara said in a statement. Aaron is due to appear at a New York court on Dec. 15.

Aaron and his co-defendants, Gery Shalon and Ziv Orenstein, were indicted on charges of computer hacking, wire fraud, securities fraud, identity theft, illegal gambling and conspiring to commit money laundering.

Aaron, who pleaded not guilty, waived his extradition and asylum in Russia and voluntarily returned to the U.S. to face the charges, the Associated Press wrote, citing Aaron's lawyer. Shalon and Orenstein, who were arrested by Israeli authorities in July 2015 and extradited to the U.S. in June, also pleaded not guilty to the charges.
