The United Kingdom’s National Cyber Security Centre, CISA, the National Security Agency, and the Federal Bureau of Investigation have released a joint Cybersecurity Advisory (CSA) reporting that the malicious cyber actor known as Sandworm or Voodoo Bear is using new malware, referred to as Cyclops Blink. Cyclops Blink appears to be a replacement framework for the VPNFilter malware exposed in 2018, which exploited network devices, primarily small office/home office routers and network-attached storage devices.
CISA encourages users and administrators to review joint CSA: New Sandworm Malware Cyclops Blink Replaces VPNFilter for additional technical details and mitigations.
