Hackers exploited Tor exit relays to generate bitcoin: research

At one point this spring, a single set of money-hungry hackers controlled nearly a quarter of the endpoint infrastructure through which the anonymizing internet browser Tor routed traffic, a researcher who tracks Tor claimed this week. The unidentified attacker likely used those Tor “exit relays” — the IP addresses through which Tor traffic passes — to manipulate the traffic and mine cryptocurrency, said the researcher, who goes by nusenu. How much bitcoin the attackers were able to generate, if any, remains unclear. It’s the latest example of how malicious hackers can subvert parts of Tor’s infrastructure for their own gain, and follows another set of malicious Tor activity documented by the same researcher last year. Users ranging from human rights workers in repressive countries to U.S. drug dealers rely on Tor to try to maintain their anonymity online. “So far, 2020 is probably the worst year in terms of malicious Tor exit relay activity since I started monitoring it about … Continue reading Hackers exploited Tor exit relays to generate bitcoin: research
