A vulnerability that security researchers said has “the widest impact in the history of Windows” could affect all versions of the operating system from the past 20 years, from Windows 95 to Windows 10. Chinese security researcher Yang Yu, director of Tencent’s Xuanwu Lab, discovered the flaw, which he named BadTunnel. Yu received a $50,000 bounty for discovering the flaw. In fact, this all started when Yu simply got bored on an airplane. He said he started to imagine different security problems and suddenly came up with a brand-new attack scenario. “After the trip, I immediately started testing it on different system configurations, and finally discovered this vulnerability in the Windows operating system,” he said.
