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.
