CISA Releases Guidance Urging Water Treatment Facilities to Disconnect Equipment From the Internet (www.privacyguides.org)

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

It's so fucking dumb. They are getting attacked, and they still need to be told to unplug? What the actual fuck?

security through obscurity is nothing but a fantasy.
