"U.S. and U.K. Issue Warnings on Russian Hackers Targeting Infrastructure"

U.S. and U.K. intelligence agencies have warned of Russian hackers exploiting now-patched flaws in Cisco networking equipment to conduct reconnaissance and deploy malware against select targets. The activity has been attributed to APT28, which is affiliated with the Russian General Staff Main Intelligence Directorate (GRU). The threat actor weaponized the vulnerability to deploy a non-persistent malware dubbed Jaguar Tooth on Cisco routers that's capable of gathering device information and enabling unauthenticated backdoor access. The attacks are part of a broader campaign against aging networking appliances and software from a variety of vendors to "advance espionage objectives or pre-position for future destructive activity."

Rising Sophistication of Chinese Hackers in Cyber Espionage Attacks.

Chinese hackers, identified as UNC3886, have exploited a zero-day vulnerability in the Fortinet FortiOS operating system to deploy backdoors onto Fortinet and VMware solutions and maintain persistent access to victim environments. The vulnerability, tracked as CVE-2022-41328, was patched by Fortinet on March 7, 2023. The attacks mounted by UNC3886 targeted Fortinet's FortiGate, FortiManager, and FortiAnalyzer appliances to deploy two different implants such as THINCRUST and CASTLETAP. The group was previously tied to another intrusion set targeting VMware ESXi and Linux vCenter servers as part of a hyperjacking campaign designed to drop backdoors such as VIRTUALPITA and VIRTUALPIE.
