Sophos reveals five-year battle against Chinese hackers exploiting its devices

Sophos, a UK cybersecurity firm, has revealed a five-year battle against Chinese hackers exploiting its devices. The company monitored the hackers' activities and identified a network in Chengdu, China, linked to state-sponsored hacking groups. The conflict began in 2018 with a breach at Sophos, leading to widespread exploitation of its firewalls. Sophos installed surveillance implants on its devices to track the hackers and discovered advanced malware techniques, including a unique bootkit. Recently, Sophos noted a shift in hacker tactics, focusing on outdated devices lacking updates. The company warns that these unpatched systems pose significant risks, urging device owners to replace unsupported products to enhance security.
