Background
Azizjon Mamashoyev was designated by OFAC in April 2026 alongside Sergey Zelenyuk and others under the Protecting American Intellectual Property Act (PAIPA) as a node in the Operation Zero exploit broker network. Mamashoyev operated Advance Security Solutions, a brokerage entity in the network through which zero-day exploits stolen from L3Harris Trenchant by Peter Williams were transacted.
The designation places Mamashoyev as one of the operational nodes in Operation Zero's distribution and acquisition pipeline, distinct from the UAE-based routing of Special Technology Services and the Russian-registered primary vehicle of Matrix LLC. OFAC's simultaneous designation of multiple individuals and entities maps the full transactional architecture of the network rather than targeting only the principal operator.
For international law enforcement, the designation provides legal footing for corresponding financial intelligence actions by partner agencies in jurisdictions where Mamashoyev or Advance Security Solutions held accounts or conducted transactions.
