The AI-assisted attacks reduce the technical expertise and time needed to develop malicious tools, posing an active threat that could disrupt critical processes, cause safety incidents, or damage equipment. The alert urges operators to patch systems and ensure PLCs are not accessible from the internet.", "body_md": "Hackers targeting US critical infrastructure, including energy and water providers, are using AI to help them break into vulnerable industrial IT systems, according to the FBI.\n\nOn Wednesday, the FBI joined with several federal agencies, including the NSA, to [warn](https://www.ic3.gov/CSA/2026/260819.pdf) the public about the “active threat,” which has been targeting Siemens-developed industrial systems connected to the internet.\n\nThe FBI is raising alarm bells, noting the hackers have been using AI to create “exploitation [scripts](https://www.pcmag.com/encyclopedia/term/script)” or malicious instructions written in computer code to help them hijack access to the internet-exposed industrial systems.\n\nThe AI use has been able to do so by harnessing publicly available information about the Siemens systems to lead to “initial access, credential access, denial of service, and other objectives,’ the alert says.\n\n“Using AI to generate exploitation scripts represents an evolution in threat actor capabilities, dramatically reducing the technical expertise and time required to develop working ICS (industrial control system) exploitation scripts and malicious tools,” the FBI added. “In addition, AI enables adversaries to rapidly leverage additional attack vectors and adapt to defensive measures.” For example, the AI-assisted scripting can create custom tools that pretend to mimic legitimate monitoring software on the industrial computers.\n\nThe alert doesn't identify the AI used. But the threat underscores a growing trend of hackers, including state-sponsored groups, using AI programs to amplify their operations. This past summer, suspected Chinese hackers [used](/ai/166678/chinese-hackers-created-a-near-autonomous-attack-using-open-source-ai) open-source AI to create a “near-autonomous attack” capable of cracking 85 government accounts reportedly in Taiwan.\n\nIn this case, the hackers have been targeting [programmable logic controllers](https://www.pcmag.com/encyclopedia/term/plc), or specialized computers used to control industrial systems. The FBI’s alert flagged PLCs under the Siemens S7 Series used in the US. The danger covers a wide range of industries including manufacturing, food and agriculture and other commercial facilities, in addition to the energy and water sector.\n\n“This is not a theoretical risk—it is an active threat. Depending on the specific circumstances, exploitation of poorly protected PLCs could lead to disruption of critical industrial processes, safety incidents, downtime or equipment damage, compromise of sensitive data, compliance violations, and cascading impacts across interconnected systems,” the alert says.\n\nThe warning seems related to a string of recent hacks that’ve been [targeting](/security/166499/fbi-hackers-targeted-water-utility-providers-in-at-least-7-states) water utility providers in at least [12](https://www.csis.org/analysis/mapping-iranian-cyberattacks-us-water-systems) US states. Last month, the FBI warned the water utility hacks involved internet-exposed PLCs under the MicroLogix 1100 and 1400 series from Rockwell Automation/Allen-Bradley.\n\nThe AI use may explain how the hackers have been able to quickly scale their efforts. Privately, the US suspects Iranian state-sponsored groups are likely behind the water utility hacks, [according](https://www.nytimes.com/2026/07/30/us/politics/minnesota-water-cyberattack-iran.html) to *The New York Times*.\n\nIn the meantime, the FBI's alert goes on to warn the hackers have been targeting Siemens PLCs set with \"unconfigured (default) or minimally configured authentication.\" In response, the agency is urging the industry to apply patches and \"ensure PLCs are NOT accessible from the Internet,\" among a host of other mitigation measures.", "url": "https://wpnews.pro/news/fbi-hackers-are-targeting-us-industrial-and-water-systems-with-help-of-ai", "canonical_source": "https://uk.pcmag.com/security/166815/fbi-hackers-are-targeting-us-industrial-and-water-systems-with-help-of-ai", "published_at": "2026-08-19 18:45:20+00:00", "updated_at": "2026-08-19 19:44:25.185174+00:00", "lang": "en", "topics": ["artificial-intelligence", "ai-safety", "ai-policy", "ai-tools"], "entities": ["FBI", "NSA", "Siemens", "Rockwell Automation", "Allen-Bradley", "The New York Times"], "alternates": {"html": "https://wpnews.pro/news/fbi-hackers-are-targeting-us-industrial-and-water-systems-with-help-of-ai", "markdown": "https://wpnews.pro/news/fbi-hackers-are-targeting-us-industrial-and-water-systems-with-help-of-ai.md", "text": "https://wpnews.pro/news/fbi-hackers-are-targeting-us-industrial-and-water-systems-with-help-of-ai.txt", "jsonld": "https://wpnews.pro/news/fbi-hackers-are-targeting-us-industrial-and-water-systems-with-help-of-ai.jsonld"}}
