Introducing C2 Detection: Know When Your Edge Devices Are Calling Home to Attackers

GreyNoise has announced the launch of a new intelligence module titled C2 Detection, designed to enhance organizational visibility into compromised edge devices. This tool provides two distinct, high-confidence signals indicating when internal assets are communicating with external attacker infrastructure, commonly known as calling home. The announcement focuses on improving threat detection capabilities regarding Command and Control activities rather than highlighting a specific active campaign, malware family, or attributed threat actor. Consequently, no specific adversarial groups or malicious software families are identified within this text. The primary impact is improved defensive posture through early detection of compromised states. Organizations are encouraged to leverage this new intelligence module to identify potential breaches within their environment. This represents a defensive advancement in threat intelligence rather than a report on a specific kinetic cyber incident or vulnerability exploitation campaign affecting the broader community at this time.

We're launching C2 Detection — a new GreyNoise intelligence module that gives you two distinct, high-confidence signals that a device in your environment has been compromised.
