CISA Releases Guidance Urging Water Treatment Facilities to Disconnect Equipment From the Internet

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

Jesus Zombie Christ an a pogo stick. Has no one been paying attention for the last two decades? Seriously, we learned this sort of lesson in Two Thousand and fucking Three. Your critical assets do not get public IP addresses.
