CISA released an urgent message warning water utilities to disconnect their logic controllers from the internet in the face of rising cyberattacks.
The hacks target internet-facing programmable logic controllers (PLCs) that control equipment and allow machinery to communicate. They monitor and control the water pressure, chemical dosing, and other factors to ensure the water is safe.
Many of the PLCs are apparently open to the internet and use default credentials, allowing a remote attacker to easily take them over.
I assume it is this CISA: https://en.wikipedia.org/wiki/Cybersecurity_and_Infrastructure_Security_Agency
Changing tech is usually a lot harder than adoption. Better methods and protocols will keep emerging to fight new digital threats but with physical threats usually don’t change. Only exception is social engineering (e.g. attacking a locked door by tricking someone into opening it). Even then a physical presence is required and someone can’t enter a locked room from 2000 miles away.
