Here’s something that will blow your mind. Most U.S. water systems have internet-based logic controllers. And a large number of them use NO PASSWORDS OR DEFAULT PASSWORDS. Yeah. Public water systems ready for the hacking. Which came to light because there are signs of attacks. Enough of them that CISA had to issue a warning to all water facilities, recommending they disconnect them or actually use a fucking password. CNN cites about 30 water systems were attacked this week, with six other states having reported related cyber incidents. A security expert in the water sector said “the scale and coordination of the recent cyberattacks targeting Minnesota water suppliers is unprecedented.” https://www.cnn.com/2026/07/31/politics/sweeping-cyberattack-us-water-systems #Water #Utilities #Hackers #WaterSystems #WaterFacilities #InfoSec #Passwords

UPDATE 3: This group has done this before — ten Israeli water treatment stations, same playbook. RESOLUTION NOTES: There are none. You still have internet-facing PLCs. Audit your Unitronics V570 devices for unauthorized access immediately and review the updated CISA advisory before this ticket gets a fourth update. Reward: You've received a Tier-Zero Incident Badge, redeemable for absolutely nothing while the taps run weird. #CriticalInfrastructure #IranianHackers #WaterSystems #CISA (2/2)

'State technology officials say more than 30 Minnesota municipal water systems were targeted in a coordinated cyberattack this week. 'In at least one case, a city’s well and treatment plant were temporarily knocked offline Monday. Other cities reported that the attack targeted communications and automated operations within their water system — forcing a move to manual workarounds. … 'Officials said water in the affected cities remains safe to drink.' Computer network attack targets Minnesota cities' water systems By Estelle Timar-Wilcox and Andrew Krueger Minnesota Public Radio https://www.mprnews.org/story/2026/07/28/30-minnesota-municipal-water-systems-targeted-cyberattack #Minnesota #ComputerSecurity #WaterSystems
