The US Treasury Office of Foreign Assets Control (OFAC) used the Protecting American Intellectual Property Act (PAIPA) for the first time in a cyber matter, sanctioning Sergey Sergeyevich Zelenyuk, his firm Matrix LLC trading as Operation Zero, and five associated individuals and entities for acquiring and distributing US government cyber tools1. PAIPA was originally drafted to punish intellectual-property theft that harms US competitiveness; applying it to a Russian exploit broker creates a new sanctions lane alongside the traditional Specially Designated Nationals (SDN) regime, one tuned specifically to the exploit-supply chain.
The underlying theft anchors the case. Per US Department of Justice (DOJ) sentencing documents, Peter Williams, a 39-year-old Australian national and former executive at Trenchant, the cyber unit inside US defence contractor L3Harris, pleaded guilty on 29 October 2025 to stealing at least eight zero-day exploits developed exclusively for US government use and selling them to Operation Zero between 2022 and 2025. A zero-day is a software vulnerability for which no patch exists, typically sold to intelligence services for espionage or to militaries for offensive cyber operations. A federal court sentenced Williams to 87 months, roughly seven years and three months, on 24 February 2026.
The secondary designations describe the broker network's plumbing: Marina Vasanovich (Zelenyuk's assistant), Special Technology Services based in the United Arab Emirates, Azizjon Mamashoyev, Oleg Kucherov (identified as a suspected Trickbot operator), and Mamashoyev's brokerage Advance Security Solutions. The UAE vehicle is the structural insight. Russian-origin exploit brokers have been routing acquisitions through Gulf shell companies to keep sanctioned Russian entities off the paperwork. Treasury's action names that routing explicitly and punishes it, which shifts the broker market's preferred jurisdictions one step further from OFAC reach.
