CISA urges water utilities to take exposed systems down after Minnesota hacks
CISA has urged water utilities to take internet-exposed systems offline following hacking incidents targeting water infrastructure in Minnesota. A memo distributed to water industry members references Iran but stops short of formally attributing the Minnesota incidents to the country.
Why this matters: Water systems are about as critical as infrastructure gets. If someone can tamper with treatment or distribution controls remotely, the consequences are not abstract. They are physical. The CISA guidance to simply take systems offline tells you something: these utilities are connected to the internet in ways they probably should not be, and fixing that fast is easier than defending it. The Iran mention without attribution is also worth watching. Governments do not usually float a country's name in an industry memo by accident.
