- Former L3Harris manager Peter Williams sentenced to over seven years for stealing eight zero-day exploits and selling them to a Russian broker.
- The exploits, sold for up to $4 million in cryptocurrency, could have been used for global cyberattacks and espionage against military targets.
- The U.S. sanctioned the Russian exploit brokerage Operation Zero and its affiliates for acquiring and distributing these sensitive cyber tools.
A former manager of a U.S. defense contractor has been sentenced to prison for selling stolen national security secrets to a Russian buyer. Peter Williams, a 39-year-old Australian, received an 87-month sentence in February 2026 after admitting to theft of trade secrets from L3Harris.
He sold eight zero-day exploits to the Russian broker Operation Zero for millions in cryptocurrency. Consequently, the U.S. State Department announced sanctions against the broker and its director, Sergey Sergeyevich Zelenyuk.
The tools were intended exclusively for the U.S. government and select allies. Williams’s actions reportedly caused L3Harris $35 million in losses and provided Russia with access to millions of devices.
According to a sentencing memorandum, the exploits could enable crimes from ransomware to state-directed cyber-espionage. Assistant Attorney General John A. Eisenberg said Williams “auctioned them off to a Russian bidder.”
The Treasury Department also sanctioned Operation Zero and related entities. It said the broker sought to sell exploits only to non-NATO countries and foreign intelligence agencies.
Williams was ordered to forfeit assets purchased with the illicit cryptocurrency proceeds. The case highlights the lucrative and dangerous black market for critical digital vulnerabilities.
