US Agencies Warn Iran-Backed Hackers Target Infrastructure
A joint advisory from the FBI, NSA, CISA and the U.S. Department of Energy warns that Iran-backed hackers are increasingly targeting U.S. critical infrastructure. The adversaries have been exploiting internet-facing systems across sectors — including water and wastewater utilities, energy and local government facilities — and specifically targeting programmable logic controllers (PLCs) and SCADA products to manipulate device displays and configuration files. The agencies said the intrusions have caused operational disruption and financial loss. U.S. officials tied the escalation to the broader U.S.-Israel–Iran conflict. The advisory also highlights prior activity attributed to an Iran-linked group called Handala, which has been connected to attacks such as a disruptive breach at medical tech firm Stryker and a leak of partial contents of FBI director Kash Patel’s email account.
Nation-state cyberattacks on critical infrastructure and a multi-agency U.S. advisory signal elevated risk to core IT, data centers and service availability — a high-impact issue for infrastructure operators and any digital businesses reliant on cloud and operational systems.

US warns AI-aided hackers target Siemens S7 water systems
U.S. security agencies including CISA, the FBI and the NSA issued an advisory saying hackers are actively exploiting Siemens S7 programmable logic controllers (PLCs) used in critical infrastructure. The agencies warned attackers are using AI to generate exploit scripts that leverage publicly available information to find and compromise out-of-date or poorly secured PLCs, with water supply and wastewater systems across multiple U.S. states already affected. CISA reiterated long-standing guidance to keep such devices disconnected from the internet and cautioned rural communities are often more vulnerable. The advisory follows a series of recent intrusions attributed to suspected Iranian-linked actors targeting U.S. water and energy providers.
CISA: Hackers Hit 100+ U.S. Water Systems in July
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) reported that more than 100 internet-exposed systems in the U.S. water and wastewater sector were targeted by cyberattacks in July. The attacks largely targeted programmable logic controllers (PLCs) from multiple manufacturers — including Rockwell, Schneider Electric, and Siemens — and relied in part on AI tools to produce scripts capable of exploiting vulnerable PLCs. While the intrusions have caused outages and disruptions during investigations, they have had little effect on water supplies. U.S. officials say intelligence points to Iran as the likely actor but have not made a definitive attribution. The incidents raise broader concerns about the cybersecurity and resilience of U.S. critical infrastructure.
Iran Cyber Threats Rise Amid U.S. Agency Struggles
U.S. cyber officials and private-sector experts warn of an elevated risk of Iran-linked cyberattacks on American businesses and infrastructure as kinetic strikes in the Middle East intensify. The Cybersecurity and Infrastructure Security Agency (CISA) is facing operational strain from a partial government shutdown, staff furloughs, management reshuffles and key departures, which officials and lawmakers say could hamper its readiness. Private cybersecurity firms (CrowdStrike, Google’s Threat Intelligence Group) report increased activity and claims from Iran-linked groups, and major companies and financial institutions are preparing for potential disruptions. Lawmakers and DHS say they are coordinating with intelligence and law enforcement partners, while concerns persist about gaps in CISA’s capacity during the funding lapse.
