An Australian citizen working for a U.S. defense contractor has been sentenced to seven years in prison for selling sensitive cybersecurity trade secrets to a Russian-linked buyer, the U.S. Department of Justice announced. Peter Williams, 39, admitted transferring eight pieces of cyber-exploit software and intelligence to a Russian broker in exchange for $4 million in cryptocurrency, which he spent on jewelry, watches, homes, and luxury vacations.
U.S. Attorney Jeanine Pirro said the stolen tools could have allowed Moscow to access millions of digital devices, framing the crime as a serious national security violation rather than a simple theft. Williams had been the general manager of Trenchant, an intelligence firm owned by L3Harris Technologies, which develops software to help U.S. and allied intelligence agencies exploit vulnerabilities in computer networks and mobile devices, according to Australian media reports.
Between April 2022 and August 2025, Williams exploited his access to Trenchant’s secure networks to steal cyber-exploit components intended solely for the U.S. government and select allies. He sold these components under written contracts with a Russian broker, receiving $1.3 million for the transactions, which collectively were valued at $4 million in cryptocurrency. The FBI reported that Williams continued the transfers even after he became aware of an ongoing investigation into his activities.
Williams used the illicit proceeds to acquire a 2022 Tesla Model X, a 2018 Porsche Panamera, multiple properties, and high-end luxury items. FBI Special Agent Jimmy Paul stated that Williams’ actions caused “significant loss and harm” to his employer, the U.S. government, and allied partners, emphasizing that the sentence serves as a warning to anyone threatening national security.
Williams pleaded guilty on October 29, 2025, to two counts of theft of trade secrets. In addition to his 87-month prison term, he was ordered to serve three years of supervised release and to pay $1.3 million in restitution and an equal amount in forfeitures. District Court Judge Loren AliKhan highlighted that Williams’ conduct caused $35 million in damages to the defense contractor and inflicted broader harm on U.S. and allied intelligence communities, including in Australia.
Assistant Director Roman Rozhavsky of the FBI’s Counterintelligence and Espionage Division described the sentence as “a clear warning to all who consider placing greed over country,” underscoring the seriousness with which U.S. authorities treat espionage and the theft of sensitive cybersecurity tools.
