New Report Reveals Hidden Risks: How Internet-Exposed Systems Threaten Critical Infrastructure | Grey Noise Blog
Summary: A Censys report cited by GreyNoise found 145,000 industrial control systems exposed to the internet, including thousands of unsecured human-machine interfaces (HMIs). The report cites attacks in Pennsylvania and Texas where attackers used exposed HMIs to manipulate water systems, and GreyNoise's summer 2024 sensors emulating internet-connected HMIs recorded attack traffic consistent with those findings.
What's compelling: The report says these water system attacks did not require advanced ICS expertise, only access to an insecure HMI, which puts 145,000 exposed control systems within reach of actors who can skip the specialized protocols defenders have spent years protecting.
