Hackers Hit America's Tap Water: A Wake-Up Call for Local Infrastructure

A coordinated cyberattack briefly disrupted dozens of Minnesota water utilities and other states by breaching internet-connected controls at local plants, likely part of a broader Iranian operation. The incident exposed long-standing vulnerabilities in aging, under-resourced, small-town water systems and the ease with which PLCs can be accessed with weak or no passwords. While no deaths or widespread service loss occurred and taps remained drinkable, experts warn of greater risk and urge better cybersecurity, information sharing, and the possibility of unplugging critical controls from the internet to prevent future breaches.
