Detailed Description: The text outlines a significant cybersecurity incident involving a zero-day exploit that affected Sophos firewalls, highlighting both the vulnerability of critical infrastructure and the implications for U.S. national security.

– The Department of Justice (DoJ) accused a Chinese business, Sichuan Silence Information Technology Co. Ltd., and an employee named Guan Tianfeng of exploiting a critical SQL injection vulnerability (CVE-2020-12271) in Sophos firewalls.
– It was determined that the exploit led to the compromise of approximately 81,000 firewalls, of which at least one was used by a U.S. government agency.
– The attack utilized a domain name similar to the legitimate Sophos update site (sophosfirewallupdate.com) to deliver malware, extracting information from compromised devices and sending it back to a Chinese IP address.
– The U.S. government highlighted that Sichuan Silence is involved with the People’s Republic of China (PRC) intelligence services, offering a variety of cyber-related services, including network exploitation and email monitoring.
– Following the indictment of Guan, the U.S. announced a reward of up to $10 million for information leading to his identification or location.
