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

Except you skipped the part where IT is ridiculously underfunded and treated like crap ("We're a utility, not a tech company!")

With constant turnover, the person receiving the "Just make it work" call is about 6 layers removed from the person who originally set up the infrastructure, and probably completely unaware of all the previous security holes put in "because it's air-gapped, it doesn't matter."
