Peter Williams

Peter Williams, a 39-year-old Australian national, was a senior executive at Trenchant, the cyber operations unit of US defence contractor L3Harris. Between 2022 and 2025 he stole at least eight zero-day exploits developed exclusively for US government use and sold them to Operation Zero, the Russian exploit brokerage operated by Sergey Zelenyuk. Williams pleaded guilty on 29 October 2025 and was sentenced to 87 months (7 years, 3 months) by a federal court on 24 February 2026.

The conviction established the criminal predicate for the subsequent OFAC sanction against Zelenyuk and Matrix LLC. Williams had access to the exploits in his executive role at Trenchant, a unit that developed offensive cyber tools exclusively under US government contracts. His case is the most significant documented insider-theft of US government cyber capability since the 2017 Reality Winner NSA data case, in terms of the technical value of the materials transferred.

The sentencing at 87 months, above the federal sentencing guideline range, reflects the severity the DOJ attached to the transfer of government cyber capabilities to a Russian-government-aligned broker. The case also anchors the OFAC PAIPA action: the civil sanction targets the broker network that Williams supplied, making the insider prosecution and the Treasury designation two parts of a single enforcement action against the exploit-broker supply chain.
