# Ex-Defense Exec Sold US Hacking Tools to Russian Broker for Millions

A 39-year-old Australian national and former defense contractor executive has been sentenced to over seven years in federal prison for stealing and selling classified zero-day exploits to a Russian broker, compromising critical U.S. national security tools in what authorities describe as a brazen act of espionage[1][2]. Peter Williams, who served as the general manager of Trenchant—a specialized cybersecurity unit within L3Harris—stole at least eight protected exploit components intended exclusively for the U.S. government and its Five Eyes intelligence partners, then sold them to a Russian firm operating as Operation Zero for up to $4 million in cryptocurrency[1][2].

The case represents one of the most significant breaches of U.S. cyber defense capabilities in recent years, with prosecutors estimating the stolen tools caused $35 million in losses and could have enabled adversaries to access millions of devices worldwide[1][2]. Simultaneously, the U.S. Treasury Department sanctioned Operation Zero and its owner, Sergey Sergeyevich Zelenyuk, for their role in acquiring and distributing the stolen cyber tools[3].

The Theft and Sale of Classified Cyber Tools

Between 2022 and 2025, Williams exploited his senior position at Trenchant to systematically steal eight proprietary cybersecurity tools built specifically for U.S. government use[1][2]. Using a portable external hard drive, he transferred the exploits out of secure networks at Trenchant's offices in both Sydney and Washington, D.C., before transmitting them to the Russian broker via encrypted channels[2].

In June 2025, just days before meeting with the FBI to discuss their investigation into the theft, Williams signed an agreement with the Russian buyer to sell stolen code for $500,000 and immediately transmitted the materials[1]. Court documents reveal that Williams received approximately $1.3 million in cryptocurrency for the complete sale of all eight exploits between 2022 and July 2025[5]. The stolen tools were surveillance and hacking instruments designed to protect U.S. national security, making their sale to a foreign adversary an act of unprecedented betrayal[10].

National Security Impact and Potential Consequences

U.S. Attorney Jeanine Pirro emphasized the gravity of Williams' crimes, stating that "these incredibly powerful tools would have allowed Russia to access millions of digital devices" and characterizing the offense as not merely theft but a crime of national security[1]. The stolen exploits could enable fraud, ransomware, espionage, and offensive cyber operations targeting civilian and military victims worldwide[1].

According to court documents, the tools were intended only for the U.S. government and select allies, and their compromise represents a catastrophic loss of competitive intelligence advantage[1]. The potential exposure of millions of devices to Russian state-sponsored cyber attacks underscores the critical nature of these tools and the severity of Williams' betrayal[2].

Operation Zero and Russian Exploit Broker Network

Operation Zero, headquartered in St. Petersburg, Russia, and led by Sergey Sergeyevich Zelenyuk, has been active as an exploit broker since 2021[7]. The firm advertises itself as a reseller of hacking tools exclusively to non-NATO customers and has publicly offered millions of dollars in bounties to cybersecurity researchers for exploits targeting U.S.-built operating systems and encrypted messaging applications like Telegram[6][7].

The Treasury Department's sanctions announcement revealed that Operation Zero resold the stolen tools "to at least one unauthorized user," though the specific recipient was not disclosed[3][4]. The firm also operates through affiliated entities, including a UAE company called Special Technology Services and another exploit broker called Advance Security Solutions operating in the UAE and Uzbekistan[4]. Treasury officials indicated that Operation Zero has sought to sell exploits to foreign intelligence agencies and develop additional cyber intelligence systems, including spyware and methods to extract personal data from artificial intelligence applications[1].

Sentencing and Legal Consequences

Williams was sentenced on Tuesday to seven years and three months in federal prison, falling short of the nine-year sentence prosecutors had requested[4]. The court also imposed a $250,000 fine and ordered mandatory restitution of $35 million for losses incurred by the theft and sale of the tools[4]. A hearing to determine Williams' full restitution obligations is scheduled for later in 2026[4].

The sentencing reflects the severity with which federal authorities treat the theft and sale of national security technology. Treasury Secretary Scott Bessent stated: "If you steal U.S. trade secrets, we will hold you accountable. Treasury will continue to work alongside the rest of the Trump administration to protect sensitive American intellectual property and safeguard our national security."[3]

They are extremely valuable because they provide ready-made hacking tools that can quickly access government networks, defense contractors, and critical infrastructure without detection[3]. The stolen exploits in this case could have enabled access to millions of computers and devices worldwide[6].

How much money did Williams receive for selling the hacking tools? Williams received approximately **$1.3 million in cryptocurrency** for selling all eight zero-day exploits between 2022 and July 2025[5]. Court documents indicate he signed an agreement in June 2025 to sell stolen code for $500,000, with the total value of the tools reaching up to $4 million based on prosecution estimates[1].
