US Sanctions Member of China’s Cyber Hacker Army [Video]

A Chinese national has been indicted and a cybersecurity company has been sanctioned over their alleged involvement in a state-affiliated hacking ring that targeted networks worldwide.

The United States District Court for the Northern District of Indiana has issued an arrest warrant for Guan Tianfeng, 30, charging him with conspiracy to commit computer fraud and conspiracy to commit wire fraud. Guan is accused of working with co-conspirators to exploit vulnerabilities in firewalls sold by U.K.-based security software and hardware company Sophos.

According to the indictment, Guan helped develop and test malware that exploited a zero-day vulnerability—a flaw unknown to developers or security teams, making it vulnerable to immediate attack. The group allegedly disguised their activity by registering domains designed to look like they belonged to Sophos.
