China-based hacker accused of deploying malware to exploit global firewall devices
Chinese Hacker Charged in Global Cybersecurity Breach
A federal court in Hammond, Indiana, has charged Guan Tianfeng, a citizen of China, for his involvement in a 2020 hacking conspiracy targeting firewall devices worldwide. Guan and his team exploited a vulnerability in firewalls made by UK-based Sophos Ltd., a cybersecurity company. They worked from Sichuan Silence Information Technology Co. Ltd. in China to create malware that infected around 81,000 devices globally, including one used by a US agency.
The malware was designed to steal data and encrypt files if victims attempted to fix the infection. Sophos quickly identified the breach and deployed fixes within two days, mitigating the impact. Despite attempts to modify the malware for ransomware encryption, these efforts failed.
The US Department of Justice is committed to holding cybercriminals accountable, especially those from China. Deputy Attorney General Lisa Monaco emphasized the importance of global cooperation in tackling cyber threats. Guan's company, Sichuan Silence, has ties to the Chinese government, raising concerns about its activities.
Sophos's "Pacific Rim" investigation revealed ongoing attacks by Chinese hacking groups, including the CVE-2020-12271 vulnerability. In response, the US Department of State offers rewards for information on Guan, and the Treasury has sanctioned him and Sichuan Silence.
This case highlights the growing cybersecurity threats and the US government's efforts to combat them. The National Security Division's Cyber Section is prosecuting the case, with the FBI continuing investigations.
