Chinese Hacker Hit with US Charges: Firewall Attacks Unmasked!
The US government charges Chinese national Guan Tianfeng with hacking Sophos firewalls, exploiting zero-day vulnerabilities. Linked to state-sponsored actors, the attacks compromised over 81,000 devices worldwide. Sanctions target Guan and Sichuan Silence, his alleged employer. The FBI wants him on their Cyber’s Most Wanted list, and a $10 million reward is up for grabs.

Hot Take:
Looks like the US government has decided to throw some serious shade at Chinese hackers, serving up a legal one-two punch with charges and sanctions. Guan Tianfeng, aka GBigMao, might want to consider changing his online alias to “GBigTrouble” because the heat is officially on. With the US offering a $10 million reward, maybe he should start a GoFundMe for his defense fund. And who knew that “Silence” could make so much noise?
Key Points:
- The US charged and sanctioned Chinese national Guan Tianfeng for hacking Sophos firewalls.
- Sophos tracked the zero-day vulnerabilities exploitation for five years.
- The campaign compromised approximately 81,000 firewall devices globally.
- Sichuan Silence Information Technology allegedly provided services to China’s Ministry of Public Security.
- The US Department of State is offering a $10 million reward for information on Guan.
