Peter Williams, Ex-ASD, Pleads Guilty to Selling Eight Exploits to Russia
Presented by
Policy & Intelligence
The former general manager of a US defence contractor, Peter Williams, has pleaded guilty to selling "eight sensitive and protected cyber-exploit components" to Russian 0day broker Operation Zero*.
The broker claims to buy exploits from developers and resell them to non-NATO buyers, including the Russian government.
Williams, an Australian national, was previously employed by Australia's signals intelligence agency ASD, from around 2007 to the mid-2010s. He later joined Linchpin Labs, which was acquired alongside Azimuth Security to form what eventually became L3Harris Trenchant, the vulnerability and exploit development subsidiary of L3Harris. By the time of his arrest, Williams had become the general manager there.
