RedNovember, a Chinese state-sponsored threat group, has expanded its cyber-espionage activities globally. The group targets high-profile government, intergovernmental, and private sector organizations, focusing on defense, aerospace, and technology sectors. It uses the Go-based backdoor Pantegana and Cobalt Strike for intrusions, exploiting vulnerabilities in perimeter appliances. RedNovember's tactics include combining weaponized proof-of-concept exploits with open-source tools, allowing for scalable operations and attribution obfuscation. The group has shown particular interest in targets across the US, Taiwan, South Korea, and Panama, often aligning its activities with geopolitical events and Chinese strategic interests.
Salt Typhoon is a Chinese state-sponsored threat actor targeting major telecommunications providers globally by exploiting vulnerabilities in various network devices. This analysis monitors exposures of internet-facing devices linked to Salt Typhoon activity over six months, including Sophos Firewalls, Cisco IOS XE WebUIs, Ivanti Connect Secure, and Fortinet FortiClient EMS systems. Overall exposure decreased by 25%, with Sophos Firewall interfaces showing the largest reduction, while Cisco IOS XE exposure increased. Most exposures are concentrated in the United States, except for Sophos XG Firewall exposures in Germany. The persistence of exposed devices suggests ongoing challenges in remediation and organizational response.
