Google found a series of hacking tools they said were used by a Russian espionage group and a cybercriminal group in China. Sources from a U.S. government defense contractor said some of those hacking tools were theirs.

Peter Williams, the former head of U.S. hacking tools maker L3Harris Trenchant, was sentenced to seven years in prison for stealing and selling his former company’s hacking and surveillance tools to a Russian firm.

The U.S. Treasury announced it was imposing sanctions against a Russian broker of zero-day exploits, its founder and two affiliates, citing a threat to U.S. national security. Another affiliated zero-day broker in the United Arab Emirates was also sanctioned.

Prosecutors confirmed Peter Williams, the former Trenchant boss, sold eight exploits to a Russian buyer. TechCrunch exclusively reported that the Trenchant division was investigating a leak of its hacking tools, after another employee was accused of involvement.

The U.S. Department of Justice accused Peter Williams, former general manager of L3Harris’ hacking division Trenchant, of stealing trade secrets and selling them to a buyer in Russia.
