Former Tor developer created malware to hack Tor users for the FBI

Patrick O'Neill writes: Matt Edman is a cybersecurity expert who worked as a part-time employee at Tor Project, the nonprofit that builds Tor software and maintains the network, almost a decade ago. Since then, he's developed potent malware used by law enforcement to unmask Tor users. It's been wielded in multiple investigations by federal law-enforcement and U.S. intelligence agencies in several high-profile cases.
