A former senior executive at a US defense contractor has been sentenced to more than seven years in federal prison after admitting he stole highly sensitive cyber tools and sold them to a Russian cyber broker.
Peter Williams, 39, an Australian national and former general manager at a US-cleared defense contractor, was sentenced in the US District Court for the District of Columbia to 87 months in prison.
In addition to his prison term, the court ordered three years of supervised release, forfeiture of $1.3 million, cryptocurrency holdings, a residential property, and luxury items, including watches and jewelry.
A restitution hearing is scheduled for May 12, 2026.
Williams pleaded guilty in October 2025 to two counts of theft of trade secrets.

According to court filings, between 2022 and 2025, Williams used his privileged access to his employer’s secure internal network to steal eight highly sensitive cyber-exploit components.
The software was developed for national security purposes and was intended exclusively for sale to the US government and select allied nations.
Federal prosecutors said the stolen tools were not ordinary commercial software. They were sophisticated cyber capabilities designed for intelligence and defensive operations. These were the tools that could potentially compromise millions of digital devices if misused.
Investigators said Williams transferred the components to a Russian cyber-tools broker using encrypted communications. The broker publicly markets itself as a reseller of cyber exploits and advertises clients that include the Russian government.
Millions in Cryptocurrency Payments
Prosecutors revealed that Williams entered into multiple written contracts with the Russian broker. The agreements covered upfront payments for the stolen components and additional recurring payments for follow-on technical support.
In exchange, Williams received promises of up to $4 million in cryptocurrency. Authorities said he used the proceeds to fund luxury vacations, purchase high-end jewelry, designer clothing, watches, and invest in property.

Assistant Attorney General for National Security John A. Eisenberg said Williams deliberately exploited his position for financial gain.
“Williams exploited his senior role at a US defense contractor to enrich himself at the expense of the US and his employer,” Eisenberg said. “The tools he compromised were intended to protect this Nation; instead, he auctioned them off to a Russian bidder.”
$35 Million in Losses and National Security Risks
Court documents state that Williams’ actions caused at least $35 million in financial losses to the defense contractor. But officials stressed that the broader consequences extended far beyond monetary damage.
US Attorney Jeanine Pirro for the District of Columbia described the offense as a direct threat to national security.
“By betraying a position of trust and selling sensitive American technology, Williams’ crime is not only one of theft, but it is a crime of national security,” Pirro said. “Our nation’s defense capabilities are not commodities to be auctioned off.”
During sentencing, the presiding judge noted that the theft of national security-focused software inevitably harms intelligence communities in both the US and allied countries.
Williams acknowledged that his conduct had a significant impact on US and allied government customers who relied on the contractor’s cyber capabilities.

FBI: Warning to Insiders
The Federal Bureau of Investigation’s Baltimore Field Office led the investigation.
Assistant Director Roman Rozhavsky of the FBI’s Counterintelligence and Espionage Division said the breach strengthened the capabilities of foreign cyber actors.
“Williams placed greed over the country and gave Russian cyber actors an advantage,” Rozhavsky said. “If you betray your position of trust and sell sensitive American technology to foreign adversaries, the FBI will not rest until you are brought to justice.”
Officials warned that international cyber brokers are emerging as a new class of digital arms dealers. They operate in the shadows but can reshape global cyber conflicts.
Broader Government Action
On the same day as the sentencing, the US Department of the Treasury’s Office of Foreign Assets Control (OFAC) and the Department of State announced separate measures aimed at disrupting the Russian cyber-tools broker and its operators.
Authorities say the case highlights growing concerns about insider threats in the defense and cybersecurity sectors. This is because sensitive tools intersect with cryptocurrency payments and encrypted communications.
Each count of theft of trade secrets carries a statutory maximum of 10 years in prison and significant financial penalties. Though Williams received 87 months, federal officials emphasized that insider-driven cyber espionage will continue to draw aggressive prosecution.

The case was prosecuted by Assistant US Attorneys Tejpal Chawla and Jason McCullough for the District of Columbia, along with attorneys from the Justice Department’s National Security Division.
Amid global cyber tensions, the Williams case serves as a sharp reminder that access to sensitive digital weapons carries profound responsibility, and that the consequences of betrayal can be severe.
