PolarEdge Targets Cisco, ASUS, QNAP, Synology Routers in Expanding Botnet Campaign

Cybersecurity researchers have analyzed the PolarEdge botnet malware, which targets routers from Cisco, ASUS, QNAP, and Synology to control infected devices. The malware uses TLS communication, anti-analysis techniques, and exploits known security flaws to operate and evade detection. #PolarEdge #CVE-2023-20118

Keypoints

  • PolarEdge malware was first documented in February 2025, targeting specific routers for a yet-unknown purpose.
  • The botnet communicates via TLS using mbedTLS and supports connect-back and debug modes.
  • It exploits a known security vulnerability (CVE-2023-20118) to download and execute a backdoor shell script.
  • The malware employs anti-analysis techniques, including process masquerading and configuration obfuscation.
  • Recent findings link GhostSocks, a malware-as-a-service, to converting infected devices into SOCKS5 proxies for monetization.
