Intelligence Profile

According to CISA, Cyclops Blink appears to be a replacement framework for the VPNFilter malware exposed in 2018, and which exploited network devices, primarily small office/home office (SOHO) routers and network attached storage (NAS) devices. Cyclops Blink has been deployed since at least June 2019, fourteen months after VPNFilter was disrupted. In common with VPNFilter, Cyclops Blink deployment also appears indiscriminate and widespread. The actor has so far primarily deployed Cyclops Blink to WatchGuard and ASUS devices, but it is likely that Sandworm would be capable of compiling the malware for other architectures and firmware.
