Grey Noise | Industrial Control Systems (ICS) and Grey Noise tagging
Summary: GreyNoise researchers have identified and created tags for ICS-related protocols, which the post says attackers and defenders both scan for on the internet. The post notes that many ICS vendors wrapped legacy serial-based protocols inside TCP or UDP to make devices network-ready, without security as a priority.
Bottom line: ICS environments are described as slow to change and biased toward legacy technology, and their critical nature means updates and replacements are risky and costly - so the exposed devices attackers scan for are the ones hardest to fix.
