The Hunt: Uncovering Misconfigurations Through Proactive Threat Hunting to Fortify Cybersecurity in OT Environments

Summary: Dragos OT Watch reports that 100% of its customers had at least one significant misconfiguration in their OT environments, found through an initial "Low Hanging Fruit Threat Hunt" run at onboarding. Examples include hosts with DNS pointed at external resolvers like Google DNS, insecure remote access present in over 10% of customer OT environments, and a real-time automation controller configured to poll an external IP address instead of an internal asset.

What you should know: In one case, a vendor's unapproved remote access was found and revoked, and the vendor was compromised weeks later - the hunt closed a door an attacker would otherwise have walked through. Every customer checked so far has had at least one such gap, so the odds your OT estate is clean are not good.
