The Senate’s top Democrat called on the Department of Homeland Security Friday to work closely with state and local governments to defend against artificial intelligence-strengthened hacks. 

Senate Minority Leader Chuck Schumer, D-N.Y., wrote to DHS Secretary Markwayne Mullin to make sure state, local, tribal and territorial (SLTT) governments aren’t left behind as AI models advance, posing new hacking threats.

“There is a race between cybersecurity defenders and AI-enabled hacking — and there’s no time to waste,” Schumer wrote.

“While the White House has reportedly begun hosting meetings about its internal security priorities following these frontier AI cyber breakthroughs, it is glaringly obvious that the Department of Homeland Security needs an updated plan for coordinating these efforts with [state, local, tribal and territorial] governments and implementing procedures to reduce the risk of disruptive cyberattacks enabled by frontier AI,” he stated.

Schumer said he was worried about the capabilities of DHS and its Cybersecurity and Infrastructure Security Agency to carry out that coordination, given federal funding cuts to the Multistate Information Sharing and Analysis Center, and the lack of a Senate-confirmed CISA director for the duration of the second Trump administration.

Schumer wants a plan from DHS by July 1 on coordinating with state and local governments on a range of questions, such as how to identify top AI talent, carry out rapid patching and conduct risk assessments.

“AI is changing the cyber battlefield fast — and we cannot let hackers get there first,” Schumer said in comments accompanying the letter. “Hospitals, power grids, water systems, schools, elections, and emergency services cannot be left exposed while criminal gangs and state-backed hackers race to exploit new AI tools. DHS must immediately help states and localities find and fix vulnerabilities before Americans are hit with outages, disruptions, and attacks that could put lives and livelihoods at risk.”

CISA is using AI to help on the defensive side internally, agency officials recently said.

The fallout and potential exposure from Iran’s state-backed targeting of U.S. critical infrastructure extends to more than 5,200 internet-connected devices, researchers at Censys said in a threat intelligence brief Wednesday. 

 Of the programmable logic controllers manufactured by Rockwell Automation/Allen-Bradley that Censys identified as  potentially exposed to Iranian government attackers, nearly 3,900, or about 3 out of every 4, are based in the United States. 

The cybersecurity firm identified the devices based on details multiple federal agencies shared in a joint alert Tuesday, and published additional indicators of compromise, including operator IPs and other threat hunting queries.

Federal authorities earlier this week warned that Iranian government attackers have exploited devices that control industrial automation processes and disrupted multiple sectors during the past month. Some victims also experienced financial losses as a result of the attacks, officials said. 

The operational technology devices are deployed across the energy sector, water and wastewater systems, and U.S. government services and facilities. 

Censys scans spotted 5,219 internet-exposed Rockwell Automation/Allen-Bradley PLC hosts shortly after the joint alert was issued by the FBI, National Security Agency, Cybersecurity and Infrastructure Security Agency, Environmental Protection Agency, Energy Department and U.S. Cyber Command. 

Researchers at Censys determined most of the exposed devices are connected via cellular systems, posing a significant risk to remote field deployments. Nearly half of the devices globally are connected to Verizon’s wireless network and 13% are connected to AT&T’s infrastructure.

“These devices are almost certainly field-deployed in physical infrastructure (pump stations, substations, municipal facilities) with cellular modems as their sole internet path,” Censys researchers wrote in the report. 

The potential attack surface is also amplified by additional services exposed in other ports on these devices, a discovery that Censys warned could allow attackers to gain direct paths to operations beyond PLC exploitation. 

Researchers fingerprinted MicroLogix and CompactLogix models exposed to the latest threat campaign and published a list of the 15 most-exposed products. Many of the most prominent devices are running end-of-life software, a compounding risk that could allow attackers to prioritize unpatched devices upon scanning, according to Censys.

The attacks date back to at least March, following the U.S. and Israel’s war against Iran, and were underway as other Iranian government-backed attackers claimed other victims, including Stryker and local governments.

Iranian government hackers are launching disruptive cyberattacks on American energy and water infrastructure, U.S. government agencies “urgently” warned Tuesday.

The hackers are taking aim at devices and systems that control industrial processes, and have harmed victims in the last month following the onset of U.S.-Israel strikes against Iran, according to the joint alert from the FBI, National Security Agency, Cybersecurity and Infrastructure Security Agency, Environmental Protection Agency, Energy Department and Cyber Command.

“Iran-affiliated advanced persistent threat (APT) actors are conducting exploitation activity targeting internet-facing operational technology (OT) devices, including programmable logic controllers (PLCs) manufactured by Rockwell Automation/Allen-Bradley,” the alert states. “This activity has led to PLC disruptions across several U.S. critical infrastructure sectors through malicious interactions with the project file and manipulation of data on human machine interface (HMI) and supervisory control and data acquisition (SCADA) displays.”

U.S. government agencies have warned before about Iranian hackers going after similar targets with those similar methods. The first such warning came after an Iranian government-linked group took credit for attacking a Pennsylvania water facility in late 2023.

Since March of this year, however, the agencies said they have seen new victims emerge from an advanced persistent threat group tied to Iran.

“The authoring agencies identified (through engagements with victim organizations) an Iranian-affiliated APT-group that disrupted the function of PLCs,” the alert reads. “These PLCs were deployed across multiple U.S. critical infrastructure sectors (including Government Services and Facilities, WWS, and Energy sectors) within a wide variety of industrial automation processes. Some of the victims experienced operational disruption and financial loss.”

The earlier campaign compromised at least 75 devices, the alert states.

The latest disruptions include “maliciously interacting with project files, and manipulating data displayed on HMI and SCADA displays,” according to the agencies’ warning.

After the U.S.-Israel conflict with Iran began, Tehran-connected hackers claimed victims including major medtech company Stryker, local governments and more.

The FBI warned last month that Iranian hackers were deploying malware over the Telegram app, although that campaign also predated the current Iran conflict.
