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
Oh for sure, air gapped sensors that relay information are going to be necessary. We should be building these systems with absolute security because they are critical to infrastructure.
Some people will say it’s too hard to retrofit onto legacy equipment, but all it really means is adding a secondary system on top of the legacy system. Just a sensor array that has no interaction with existing systems.
Yup. Fancy architecture diagram:
