Advance Security Solutions

Advance Security Solutions is the exploit brokerage operated by Azizjon Mamashoyev, designated by OFAC in April 2026 as part of the Operation Zero sanctions action. Mamashoyev was one of five individuals and entities designated alongside principal Sergey Zelenyuk and his firm Matrix LLC under the Protecting American Intellectual Property Act (PAIPA) for acquiring and distributing US government cyber tools stolen by former L3Harris Trenchant executive Peter Williams.

Advance Security Solutions functions as a node in the Operation Zero network's distribution and acquisition pipeline, providing brokerage services distinct from the UAE-based routing of Special Technology Services. Its designation alongside the primary corporate vehicle and principal individuals maps the multi-entity structure OFAC will hold collectively accountable.

For the wider zero-day market, the OFAC action's coverage of satellite brokerage entities like Advance Security Solutions signals that Treasury is targeting the full transactional network, not only the visible front company. Buyers, intermediaries and routing vehicles are all within scope of PAIPA enforcement.
