The Cring ransomware group continues to make a name for itself through attacks on aging ColdFusion servers and VPNs after emerging earlier this year.
Experts like Digital Shadows Sean Nikkel told ZDNet that what makes Cring interesting is that so far, they appear to specialize in using older vulnerabilities in their attacks.
In a previous incident, Cring operators exploited a two-year-old FortiGate VPN vulnerability to target end-of-life Microsoft and Adobe applications. This should be a wake-up call for system owners everywhere who are using end-of-life or otherwise unsupported systems that are exposed to the internet at large, Nikkel said.
