US Treasury Slaps Sanctions on Russian Zero-Day Exploit Broker
Operation Zero and its founder hit with sanctions for trafficking in stolen US defense exploits.
The US Treasury just dropped the hammer on Operation Zero, a Russian zero-day exploit broker, and its founder Sergey Zelenyuk. The charge? Acquiring and reselling stolen exploits targeting US defense systems.
Zero-day exploits — vulnerabilities unknown to software makers — are the crown jewels of the cyber weapons trade. Operation Zero built a business around snapping them up and flipping them to buyers, a shadow market that thrives on secrecy.
The sanctions target both companies and individuals involved in the operation. This effectively freezes any US-based assets and bars American entities from doing business with them.
The move signals Washington is getting more aggressive about going after the exploit supply chain, not just the hackers deploying the weapons but the middlemen brokering them. The zero-day marketplace just got a lot more uncomfortable for its participants.
