The attacks are part of an escalating campaign linked to suspected Iranian hackers that has already hit water facilities in Minnesota, Michigan, Arkansas, Georgia, and New Jersey. Vulnerable devices are typically internet-connected, running outdated software, or otherwise poorly secured, and rural communities are disproportionately affected. Officials continue to urge disconnecting these controllers from the internet. ## Full article daily.dev links to this article rather than hosting it. Read it at the original source: ## Questions this post answers ### Why are hackers targeting Siemens S7 programmable logic controllers in water systems? Hackers are exploiting Siemens S7 PLCs because many are internet-connected, running out-of-date software, or otherwise poorly secured, making them easy targets. CISA, the FBI, and NSA report that attackers now use AI to generate exploit scripts from publicly available information to find and exploit these vulnerable devices, and the activity is part of a broader campaign against US water and wastewater systems. _daily.dev surfaces ongoing coverage for teams tracking AI-driven threats to industrial control systems._ ### Which US states have had water systems hit by suspected Iranian cyberattacks? Water facilities in Minnesota, Michigan, Arkansas, Georgia, and New Jersey have reported intrusions tied to suspected Iranian hackers targeting critical infrastructure. CISA says this activity has escalated since Iranian hackers first began targeting internet-connected systems in water and energy sectors, with rural communities often hit hardest due to the large geographic areas these systems serve. _Security teams monitoring critical infrastructure threats can follow developing incidents like these on daily.dev._ ## Similar posts on daily.dev - [Critical infrastructure’s long, undefended tail exposed by UK energy attack](https://daily.dev/posts/critical-infrastructure-s-long-undefended-tail-exposed-by-uk-energy-attack-hajfwhwyk) · CSO Online · 0 upvotes · 0 comments - [What we know about the alleged Iranian hacks on US water utilities](https://daily.dev/posts/what-we-know-about-the-alleged-iranian-hacks-on-us-water-utilities-ppbezomds) · TechCrunch · 21 upvotes · 3 comments --- Tags: [#security](https://daily.dev/tags/security) [View this post on daily.dev](https://daily.dev/posts/us-says-hackers-are-targeting-vulnerable-water-systems-with-the-help-of-ai-porstq8vm) ```json {"@context":"https://schema.org","@graph":[{"@type":"Organization","@id":"https://daily.dev/#organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180},"sameAs":["https://twitter.com/dailydotdev","https://github.com/dailydotdev","https://www.linkedin.com/company/daily-dev-ltd"]},{"@type":"WebSite","@id":"https://daily.dev/#website","url":"https://daily.dev","name":"daily.dev","publisher":{"@id":"https://daily.dev/#organization"},"potentialAction":{"@type":"SearchAction","target":{"@type":"EntryPoint","urlTemplate":"https://daily.dev/search?q={search_term_string}"},"query-input":"required name=search_term_string"}}]} {"@context":"https://schema.org","@type":"TechArticle","headline":"US says hackers are targeting vulnerable water systems with the help of AI","url":"https://daily.dev/posts/us-says-hackers-are-targeting-vulnerable-water-systems-with-the-help-of-ai-porstq8vm","mainEntityOfPage":{"@type":"WebPage","@id":"https://daily.dev/posts/us-says-hackers-are-targeting-vulnerable-water-systems-with-the-help-of-ai-porstq8vm"},"datePublished":"2026-08-20T12:46:35.339Z","dateModified":"2026-08-25T21:24:32.042Z","description":"CISA, the FBI, and the NSA warn that hackers, using AI to generate exploit scripts, are actively targeting Siemens S7 programmable logic controllers used in...","image":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b115515f2421c0aa6bb68dca3aeadde4?_a=AQAEuop","thumbnailUrl":"https://media.daily.dev/image/upload/f_auto,q_auto/v1/posts/b115515f2421c0aa6bb68dca3aeadde4?_a=AQAEuop","isAccessibleForFree":true,"articleSection":"TechCrunch","inLanguage":"en","publisher":{"@type":"Organization","name":"daily.dev","url":"https://daily.dev","logo":{"@type":"ImageObject","url":"https://daily.dev/apple-touch-icon.png","width":180,"height":180}},"author":{"@type":"Organization","name":"TechCrunch","logo":"https://media.daily.dev/image/upload/t_logo,f_auto/v1/logos/tc","url":"https://daily.dev/sources/tc"},"commentCount":0,"discussionUrl":"https://daily.dev/posts/us-says-hackers-are-targeting-vulnerable-water-systems-with-the-help-of-ai-porstq8vm","interactionStatistic":[{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":0},{"@type":"InteractionCounter","interactionType":{"@type":"CommentAction"},"userInteractionCount":0}],"keywords":"security","timeRequired":"PT2M"} {"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"name":"Home","item":"https://daily.dev"},{"@type":"ListItem","position":2,"name":"TechCrunch","item":"https://daily.dev/sources/tc"},{"@type":"ListItem","position":3,"name":"US says hackers are targeting vulnerable water systems with the help of AI"}]} {"@context":"https://schema.org","@type":"FAQPage","@id":"https://daily.dev/posts/us-says-hackers-are-targeting-vulnerable-water-systems-with-the-help-of-ai-porstq8vm#faq","mainEntity":[{"@type":"Question","name":"Why are hackers targeting Siemens S7 programmable logic controllers in water systems?","acceptedAnswer":{"@type":"Answer","text":"Hackers are exploiting Siemens S7 PLCs because many are internet-connected, running out-of-date software, or otherwise poorly secured, making them easy targets.
