US Sanctions Hammer Down on Chinese Firm for Global Cyber Mischief

This breach compromised 81,000 firewalls globally, including 23,000 in the US, and narrowly avoided causing catastrophic damage to critical infrastructure, raising serious national security concerns.

Hot Take:
Looks like Sichuan Silence Information Technology just traded in their firewall for a firestorm of sanctions! Who knew exploiting vulnerabilities could lead to such a zero-day payday of international repercussions? Guan Tianfeng might want to consider a career change—maybe one that doesn’t end with the FBI Most Wanted list?
