Washington: An Australian man residing in the United States is facing a potential prison sentence after admitting to stealing defense trade secrets from his American employer and selling them to a Russian broker. Peter Williams, 39, was condemned by senior officials from the Trump administration following his guilty plea, with accusations that he “betrayed the United States and our allies” by distributing cyber tools likely used against adversaries.

Williams entered his plea in the District of Columbia on Wednesday, local time, for two counts of theft of trade secrets. According to court documents, Williams intended to sell these secrets outside the US, specifically to a buyer based in the Russian Federation, with an estimated value of $US1.3 million ($2 million).

Details of the Crime

Prosecutors revealed that the stolen materials were taken over a three-year span from 2022 to 2025 from the American defense contractor where Williams was employed. The theft included national security-focused software, comprising “at least eight sensitive and protected cyber-exploit documents.”

The Justice Department stated that these components were intended for exclusive sale to the US government and select allies. However, Williams had traded them to a Russian cyber-tools broker, which publicly advertised itself as a reseller of cyber exploits to various customers, including the Russian government.

“His conduct was deliberate and deceitful, imperilling our national security for the sake of personal gain,” said US Assistant Attorney-General for National Security John Eisenberg.

Impact and Repercussions

Williams used his access to the company’s secure network to steal the cyber assets, reselling them “in exchange for the promise of millions of dollars in cryptocurrency,” according to the Justice Department. He engaged in multiple written contracts with the Russian broker, receiving payment for the initial sale and further periodic payments for follow-up support. The proceeds were reportedly used to purchase high-value items.

The FBI’s acting special agent in charge of the investigation, Alexander Arnett, emphasized the gravity of Williams’ actions. “The harm caused by his crimes cannot be undone,” he stated.

Legal Consequences

Each charge against Williams carries a statutory maximum of 10 years in prison and a fine of up to $US250,000, or twice the pecuniary gain or loss of the offense, according to the Justice Department. The US attorney for the District of Columbia, former Fox News host Jeanine Pirro, highlighted the financial impact on Williams’ Washington-based company, which suffered losses exceeding $US35 million.

“These international cyber brokers are the next wave of international arms dealers and we continue to be vigilant about their activities,” Pirro remarked.

Industry and Government Reactions

US Attorney-General Pam Bondi commented on the case, underscoring the threat posed by cybercrime to national security. “America’s national security is NOT FOR SALE,” she declared.

While neither the government nor court documents identified Williams’ employer, reports from Reuters and US technology publications suggest he was the general manager of L3Harris Trenchant until August this year. The company, a subsidiary of defense contractor L3Harris, specializes in spyware and hacking tools for national security operations and holds US government contracts. L3Harris declined to comment.

According to TechCrunch, Trenchant sells its products to government clients in the Five Eyes intelligence alliance, comprising Australia, Canada, New Zealand, the United Kingdom, and the US.

Williams’ Background and Legal Proceedings

Williams’ lawyer, John Rowley, declined to comment on Wednesday (Thursday AEDT). Per Wired, the plea agreement mandates Williams remain under house arrest, with limited daily freedom, until his sentencing next year.

Reports from the ABC and other sources indicate Williams previously worked for the Australian Signals Directorate in the 2010s, an agency responsible for foreign intelligence collection. The ASD refrained from commenting on the case, stating only that they are aware of the reports regarding an Australian national.

Court documents reveal the US government’s intention to seize a substantial list of Williams’ assets, including a house in Washington, over 20 watches, a Louis Vuitton handbag, Moncler jackets, jewelry, and funds from multiple bank accounts, some located in Australia.
