A new bipartisan House bill would charge the federal government with developing formal guidance for defending AI models against distillation attacks.

The AI Cyber Defense Act, shared exclusively with CyberScoop ahead of release, is sponsored by Reps. Pat Harrigan, R-N.C., and George Whitesides, D-Calif. It would direct the National Institute for Standards and Technology to develop voluntary industry standards and best practices for preventing distillation attacks from foreign entities from four countries: Russia, China, Iran and North Korea.

In an interview, Harrigan told CyberScoop it is “incredibly expensive” for the U.S. AI industry to maintain its six-to-12 month lead over other countries, and distillation attacks give other parties an incentive to copy other models while keeping their own spending low.

He said he believes countries such as China are making a strategic choice to hold back on full investment of their own AI industry, instead betting they can drift behind American companies as they perform the arduous and expensive research and development to advance the field.

“One of my concerns is that our adversaries just see it as much more beneficial and productive for them as this [U.S. industry] engine burns,” said Harrigan. “Where they actually just see it as more beneficial for themselves in the short term, to hang six to 12 months behind the United States, let us burn really hot and for 5 to 10% of the spend, they can just distill and steal, and they can do that up to until the point where our market kind of falters. At which point they can turn it into high gear, having not expended those resources yet in the past, and actually leapfrog us.”

As part of that mission, NIST will first have to define what a distillation attack is, and separate it from much of the sharing and collaboration between open-weight and open-source models that have also helped drive innovation.

Distillation attacks happen when one AI model is trained on the output data and reasoning of another, usually more powerful or advanced, model. The U.S. government, along with AI companies Anthropic, OpenAI and Google, has accused Chinese companies like Moonshot AI, DeepSeek and Alibaba, of carrying out “systematic” campaigns to distill and copy U.S. commercial models.

According to AI and cybersecurity experts, these campaigns involve the use of hundreds of burner and resold accounts and false identities to bypass geographic restrictions to access U.S. frontier models, and involve thousands, sometimes millions of prompts meant to extract valuable outputs and capabilities that can be used to train a foreign model.

Meanwhile, U.S. AI companies themselves face multiple ongoing lawsuits from media organizations, creators, artists and other laborers, who allege that commercial U.S. models were originally trained on their works without any compensation or permission.  

“AI is advancing at a breakneck pace, and every month we keep China and other adversaries from stealing our progress is a month we gain to build the safeguards this technology needs,” Rep. Whitesides said in a statement to CyberScoop.

The bill would also establish an “AI Cybersecurity Roundtable” at NIST composed of governments and AI industry stakeholders that would work to develop voluntary standards for defensive use of AI in cybersecurity in critical infrastructure.

Harrigan said he envisions the roundtable as including frontier AI companies including software and hardware security experts, who can add independent third-party voices in discussions on the best way to defend IT assets in critical infrastructure and other industries. A place “where you can go and pick an off-the-shelf set of standards that says these are the best practices as we know them all today, given the current state of technology development and the threats that are out there.”

The bill defines “entities of concern” as any foreign person or organization headquartered in one of the four listed countries of concern (Russia, China, Iran and North Korea), or one operating under the direction of a company based in those countries. The director of NIST would also have the ability to designate specific individuals or organizations as entities of concern.

OpenAI disclosed Thursday it shut down two influence operations from Russia and Iran that used ChatGPT and other AI tools to create fake journalist personas and covert think tanks that successfully planted stories and narratives in mainstream news publications.

One cluster of accounts, which OpenAI calls “Dark Clark,” is attributed to Russian actors. The network focused on influencing Latin American politics and culture. Its name comes from Mia Clark, a fake AI persona the group presented as the leader of the Social Research Center, a supposed Latin American think tank used to seed propaganda in news reporting.

The group’s content primarily focused on harming Ukraine’s reputation in Latin America, though it also became involved in hot-button political issues in Argentina and Bolivia.

Based on reports generated through ChatGPT, where operatives discussed wage scales for employees and hiring and firing decisions, OpenAI researchers said it’s likely the Russian group was actually in control of the Social Research Center, rather than being an employee or observer.  

OpenAI called it “the most complex attempt to run a front identity that we’ve disrupted over the past two and a half years.”

“The available evidence indicates that the SRC’s employees in Latin America were not aware that they were working for a Russian group,” OpenAI said. “Unlike another Russia-linked ‘think tank’ that we recently exposed, the SRC appears to have produced a majority of original content via its co-opted staff.”

OpenAI cites several fact-checks and official denials from major media organizations and government officials in Latin America that appear to be in response to Dark Clark’s propaganda.

In March, Lupa Media reported on a TikTok video falsely claiming that the Ecuadorian government was using shell companies to recruit citizens to fight for Ukraine against Russia. The actors also generated and spread fake audio clips of the Ukrainian consul in Ecuador insulting Ecuadorian citizens.

During anti-government protests in Bolivia in May, the group released another fake audio clip, this time of an employee at the state water company claiming that the government was on the verge of declaring a state of emergency and shutting off water to La Paz, prompting an official denial from the Bolivian government.

The report does not attribute the activity to any specific Russian government or intelligence agency. It does mention that its operators seemed particularly interested in Politology, a successor to the Wagner Group, the Russian mercenary force previously led by Yevgeny Prigozhin. According to OpenAI, the group prompted its model for information on Politology “far more” than any other Russian organization.

The Iranian campaign used many of the same AI tools to pitch written articles on the U.S.-Iran war. Operators created at least seven different fake journalist personas who managed to place dozens of stories online through legitimate media organizations. However, the stories themselves often failed to elicit many comments or social media reactions.

“We identified almost 100 articles published or syndicated under the operation’s bylines across roughly a dozen online outlets around the world,” OpenAI said. “These were small to medium outlets, generally focused on international affairs, geopolitics, and events in the Middle East.”

OpenAI said the activity resembled “a commercial actor running a for-hire influence campaign,” but did not attribute it to a specific actor or group.

Most influence campaigns tracked by OpenAI tend to be low-impact, garnering little organic engagement online and virtually no offline impact. Campaigns are rated on an impact scale of 1-6, with few rising above a 1 or 2.

OpenAI rated the Russian campaign a 5 and the Iranian campaign a 4, indicating they were significantly more successful in breaking through to mainstream audiences, eliciting fact checks and official denials that tend to happen when a narrative becomes so big that authorities must deny it.

The computers that automate water treatment systems across the country were built for durability, not for an internet-connected world. Many still accomplish their fundamental function, but as cyberattacks on the sector mounted this summer, water industry officials say those aging systems, especially internet-exposed operational technology and programmable logic controllers, remain among the easiest ways for adversaries to break in.

Tom Dobbins, executive director of the Water Information Sharing and Analysis Center or WaterISAC, told CyberScoop the sector’s biggest ongoing weaknesses include exposed OT, vulnerable PLCs, insecure connections through integrators and poor cyber hygiene at smaller utilities, which have pushed the center to make threat sharing faster across the sector.

“We have been under attack, and our enemies, the threat actors, are stepping up their activity as the U.S. is involved in a number of conflicts around the world,” Dobbins said.

That includes not only threats from Iran, the nation the U.S. government reportedly believes is behind this summer’s water facility attacks, but also China and Russia, he said.

WaterISAC is announcing a partnership with Cyware Wednesday to use its threat intelligence platform, selecting the company in part because of its existing relationships with other industry ISACs, Dobbins said. The ISAC already has a partnership with the National Rural Water Association to serve 20,000 of the water sector’s smallest utilities, and Dobbins said Cyware would help its analysts further.

It’s a sector that faces myriad challenges, seen by many as further behind on protecting its systems due to financial and technological constraints.

“OT systems that are exposed to the internet are a major challenge, and many of these systems that are older generation need to be not accessible to the internet,” Dobbins said.

Furthermore, programmable logic controllers (PLCs) are “obviously” a “vulnerability point,” he said. 

Those two vulnerabilities were the ones most commonly linked to this summer’s attacks.

Across the sector, PLCs have been the “main point of entry” for hackers, in part because they date back to a “simpler, gentler time,” Dobbins said.

“A lot of the equipment was developed pre-cyber threats and activities,” he said. “The equipment, it’s still valuable, it still is operational, so there’s not a huge reason for or incentive for utilities to upgrade it.”

President Donald Trump has disputed the notion that Iran was behind this summer’s attacks, despite alerts from the Cybersecurity and Infrastructure Security Agency.

“Let’s put it this way: I saw a recent CISA release that pointed to Iran as threat actors, and I know that the president kind of implied that it was not Iran, but I’ll say that CISA maybe is more expert in this area than maybe the president,” Dobbins said. “The president may not have been fully briefed when he made that comment.”

But CISA has also warned of potential threats from Russia and China, he said.

Two other sources of vulnerability for the sector are external — integrators — and internal — employees.

“If those integrators are working and they have a connection into an OT system that’s not managed discretely, then a threat actor can come in through an integrator and get into a system,” he said. 

Then there’s someone “who’s actually a good employee who’s tried to do the right thing and opens an email that has a malicious link in it, so they become subject to a phishing attack,” Dobbins said.

At smaller utilities, it can be difficult to keep up with basic cyber hygiene as well, he said: changing passwords, implementing multifactor authentication.

One way that Cyware might be able to help is by leveraging its relationships with other ISACs, said Tom Stockmeyer, managing director of government and critical infrastructure at Cyware.

“We’re thrilled to add water to the portfolio and start enabling cross-sector sharing,” he said.

There is little reason to believe the war with Iran will end anytime soon. Even as efforts to resolve the conflict continue, Iran remains unpredictable, with an enduring ability to disrupt shipping and energy markets via actions in the Strait of Hormuz.

So what does a prolonged conflict mean for cybersecurity here at home? U.S. agencies need to prepare for sustained Iranian cyber operations and conduct defensive wargames now.

I spent part of my career in Navy intelligence supporting expeditionary and special warfare operations. This experience taught me to look beyond individual attacks to the larger objectives they serve. Iran’s likely objectives are relatively straightforward: impose enough pain on critical infrastructure, businesses, and public services to increase pressure on Washington, while disrupting the industrial and civilian systems that allow the U.S. to sustain military operations.

Iran may not be a top-tier cyber power like China or Russia, but it doesn’t have to be. We recently mapped 130 documented attack techniques used by five Iranian threat groups. Much of their playbook relies on well-known, repeatable techniques rather than advanced capabilities. Success does not require extraordinary capabilities, only the ability to create enough disruption, uncertainty, and delay is enough.

America’s greatest vulnerability may not be any single network or piece of critical infrastructure, but the links in between. 

Critical infrastructure: Prepare for volume, not just catastrophe

When Americans imagine a cyberattack on critical infrastructure, we tend to think of catastrophic events, such as a large-scale blackout, a poisoned water supply, or some other digital Pearl Harbor.

But in an extended conflict, the more realistic possibility is persistent attacks across many targets. Small water systems, manufacturers, transportation providers, energy infrastructure, and local governments all serve as disruptive targets. The recent string of attacks on mostly smaller water utilities across 12 states is a prime example; so too is the four-day outage of a small-scale power plant in the UK.

Attackers do not need to destroy these systems. Any intrusion that manipulates industrial systems, interrupts operations, or forces operators to determine whether equipment can still be trusted consumes valuable time and resources. Multiply that across dozens of organizations, and federal, state, local, and private-sector response capacity will be stretched thin.

The cumulative strain on the country’s ability to respond may be more important than any single attack. Iran does not need the world’s most sophisticated cyber force if its affiliated hacking groups can generate problems faster than cyber defenders can investigate and remediate them.

Defense contractors must prepare for destructive attacks

Defense contractors have long faced espionage threats targeting military secrets.  While that threat remains, the war has significantly changed Iran’s motives and risk calculus.

The same access used to steal information from the defense industrial base (DIB) can also be used to destroy data and disrupt operations. Destructive malware such as wipers and ransomware could destroy engineering files, disable production systems or force manufacturers offline, directly affecting the military’s ability to replenish equipment and supplies.

An attacker does not have to shut down production to disrupt it. Consider a compromised calibration setting, altered test result, or unauthorized change to engineering data. Discovering that an adversary had persistent access to a manufacturing environment raises difficult questions: Which files were touched? Which designs can still be trusted? Which components were manufactured from them?

The incident quickly becomes a production problem as parts must be quarantined, engineering data re-validated, and products retested.

NIST SP 800-171 and CMMC provide an essential security baseline, which makes the current pause in CMMC implementation particularly concerning. However, contractors must also be prepared to operate through destructive attacks and establish that their systems, data, and products can still be trusted. This preparedness must extend down the supply chain, where a smaller manufacturer, software provider, or managed service provider may present a greater vulnerability than a well-defended prime.

The military attack surface extends far beyond DoD networks

The U.S. military is extraordinarily capable at defending its own networks, but its operations depend on infrastructure it doesn’t own or control. Troops and equipment move on commercial railroads, materiel flows through commercial ports, and military airlift can depend on commercial carriers. Military installations and defense contractors also depend on commercial power, telecommunications, and other infrastructure.

In an ongoing conflict, those dependencies become part of the attack surface. An adversary like Iran does not have to penetrate military command-and-control to interfere with these operations. At a time when speed matters most, cyberattacks that disrupt port scheduling, corrupt logistics information, or degrade power and communications can introduce critical delays and uncertainty that hamper operations.

This is why the line between civilian and military infrastructure becomes blurred during a conflict. A commercial railroad carrying military equipment to a strategic port may be civilian infrastructure administratively, but operationally it is part of the nation’s ability to operate its military power. The same is true of the utilities, communications providers, and other civilian infrastructure supporting military installations and defense production. Their resilience can quickly become a matter of military readiness.

Cyber defense must cross organizational boundaries

American cybersecurity is organized around sectors, organizations, and authorities that make administrative sense, but aren’t necessarily designed for wartime. The boundaries between them can become a serious liability.

Our adversaries in Tehran do not care about administrative boundaries. They care about weak spots. A vulnerability anywhere in the chain connecting civilian infrastructure, industrial production, transportation, communications, and military operations can affect everything downstream.

We need to ask: Who is responsible for the cyber resilience of a commercial railroad essential to a military deployment? Who ensures the utility serving a critical defense manufacturer can withstand a sustained nation-state campaign? Who identifies the supplier whose failure could disrupt multiple defense programs? And who coordinates the response when several are attacked simultaneously?

Those questions should shape how we prepare. Critical infrastructure exercises should assume simultaneous incidents across multiple sectors and regions. We should also be extremely cautious about weakening the incentives driving cybersecurity improvements across the DIB, such as the current pause on CMMC. Additionally, defense manufacturers should also test their ability to operate through destructive attacks and determine whether their engineering data, production systems, and finished products can still be trusted.

DoD exercises should treat civilian infrastructure, including rail, ports, energy, and communications, as a routine part of the operating environment and an attractive target for adversaries. Catastrophic scenarios deserve attention, but exercises should also account for lower-level attacks that are less spectacular but still highly consequential.

Iran does not need overwhelming cyber capability to impose significant costs. Persistent disruption at home can increase political and economic pressure surrounding the war, while disruption of defense production and military logistics can make it harder for the U.S. to sustain operations abroad.

We have spent years strengthening the individual pieces of America’s cyber defenses. A prolonged war with Iran may test the links between them.

The Coast Guard and FBI boarded two foreign vessels coming to the United States last month to investigate potential cyberattacks on the ships, according to a joint statement from the agencies Wednesday.

The “joint offshore security boardings” of the two commercial ships in the Gulf of Mexico on Aug. 21 and Aug. 24 “were designed to ensure integrity of the vessel’s operational and information technology systems following indications that the networks of both vessels were compromised,” according to the joint statement.

“Currently, there are no reports of operational disruptions, vessel instability, physical danger to crews, or environmental impacts,” the statement reads. “The Coast Guard is actively managing communications with port operators, vessel owners, and local maritime stakeholders to ensure port operations continue safely and without interruption.”

The vessels were reportedly tankers carrying oil and natural gas, and the first got hacked in the Strait of Gibraltar and lost communication for over 30 hours. Authorities were said to be  investigating whether Iran, or perhaps another group seeking to exploit the conflict between Iran and the United States, was behind the attacks.

Coast Guard cyber teams have been investigating “dark fleets” carrying sanctioned oil from Iran and Russia, which rely on digital masking to hide their operations and carry enhanced cyber risks, The Wall Street Journal reported in June.

Then-President Joe Biden signed an executive order in 2024 giving the Coast Guard additional authorities to respond to cybersecurity incidents, citing the risks that a maritime cyber incident could cause “cascading” harm to the global supply chain.

The Aug. 21 boarding party included Coast Guard law enforcement personnel, Coast Guard Cyber Protection Team members, a vessel inspector and FBI Cyber Action Team operators, who boarded “to conduct a comprehensive cyber security boarding and investigation,” according to the agencies’ joint statement. A similar team made up the Aug. 24 boarding party.

“The captain, crew, and shore-side corporate staff were critical partners in helping to ensure the threats were mitigated,” the statement reads.

Top Trump administration cyber officials have refused to answer questions from reporters recently about Iranian cyberattacks during the Middle East conflict. Trump himself has rejected the idea that Iran was behind a recent spate of attacks on U.S. water facilities.

The post Coast Guard, FBI board US-bound foreign ships in order to probe for cyberattacks appeared first on CyberScoop.

The Trump administration rolled out a six-month test program in Texas on Monday that will draw on volunteer expertise and technology from cyber and artificial intelligence companies to protect the water sector.

“Project Watershed 250” is the first of the state-based, industry-centric pilot projects to cross the finish line that the Office of the National Cyber Director has previewed since the publication of its national cybersecurity strategy earlier this year. Water systems have long been viewed as among the most vulnerable and neediest critical infrastructure sectors, and in recent months the sector has been the victim of a spree of attacks.

“Project Watershed 250 is a commitment from the states, industry and federal government that we will continue to prioritize our nation’s safety and deliver on America-first policies for the American people,” National Cyber Director Sean Cairncross said at a rollout event in San Antonio Monday.

“U.S. companies are providing world-class cyber capabilities, red teaming that tests utilities’ current defenses, system hardening using the latest private sector cyber tools and AI tooling that helps utilities’ frontier cyber defenders to protect Texas water systems and scale proven solutions across the country,” he said. “This six-month pilot program is designed to make our water and wastewater critical infrastructure more resilient and resistant to cyber attacks by proactively finding and fixing system weaknesses.”

The pilot program, featuring collaboration between federal and state governments, stands in contrast to how the Biden administration tried to tackle the issue, with audit requirements that some GOP states challenged in court, forcing Biden’s Environmental Protection Agency to withdraw its rule.

“For too long, at least on the federal level, the government has admired the problem of cybersecurity in water systems,” Cairncross said. “We are going to find out what works. We’re going to target that, and we are going to scale off of this and learn lessons.”

A dozen companies — Parsons, Microsoft, Fortinet, Google Cloud, Palo Alto Networks, Amazon Web Services, Reflection AI, Cloudflare, Zscaler, Forescout, Abnormal AI and Dragos — appeared at the rollout Monday to praise the initiative and tout their contributions to it.

Not everyone praised the initiative elsewhere, however. One cyber professional who works on water security issues, speaking on condition of anonymity, said the program was “all smoke” and that “there’s no real money behind it.”

“The White House did what it always does — reached out to industry with their hands out asking for industry to pay for things the government should be doing, at least in part,” the person said.

Texas Gov. Greg Abbott said the program would be overseen by Cairncross’s office and Texas Cyber Command, which was established just last year. Abbott cited the need for the program by mentioning “an Iranian-backed cyberattack” on 30 water systems across 12 states and a 2024 attack on the water system in Muleshoe, Texas, suspected to be the work of Russian hackers.

“The need for cyber resilience is overwhelming,” Abbott said. “Many rural providers simply don’t have the resources they need to be able to protect themselves.”

Watershed 250 isn’t the only federal effort to bolster water cybersecurity, with lawmakers introducing legislation in the aftermath of the recent attacks. Past legislation that Congress has enacted also sought to tackle the problem.

As part of its “economic D-Day” against Iran, the Treasury Department designated four Iranians for sanctions Monday stemming from their alleged role in hacking critical infrastructure targets and waging cybertheft against the United States.

It’s the second time in as many weeks that the Trump administration has taken aim at the same group of alleged hackers, following on an indictment recently unsealed against cybercriminals that federal law enforcement authorities say are affiliated with the Tehran-based Mabna Institute.

A Treasury Department release points the finger at three people — Keyvan Fayyaz Ghareh Blagh, Saber Shahbazi Balujeh, Mohammad Reza Kadkhoda’i and Mojtaba Ghal’eh-Kuhi — as specifically conducting the hacks.

“Since at least late 2023, these three individuals have successfully compromised and exfiltrated data from multiple U.S. companies in various critical infrastructure sectors, including energy companies, defense contractors, healthcare institutions, information technology companies, and financial institutions,” the release states.

A fourth individual included in Monday’s sanctions, Mojtaba Ghal’eh-Kuhi, is listed as one of the leaders of the gang carrying out the Ministry of Intelligence and Security (MOIS)-directed attacks. Another listed leader, Behzad Mesri, first faced sanctions in 2018, as part of another round of sanctions focused on the Mabna Institute.

Finally, the Treasury Department designated one additional person Monday over related activity, Arman Kahzadian, for his alleged role in receiving or using business information stolen via cyber-enabled means.

The department said the Iranian hackers sometimes turn their gaze to domestic targets.

“The members of this group are also heavily motivated by personal enrichment and greed, leading some members to prioritize their own profits over operations that benefit the MOIS,” it said. “This has driven some of the group to target Iranian companies.“

Hackers that the U.S. government has identified as Iranian have been behind a spate of attacks on U.S. water facilities, despite denials from President Donald Trump himself about Iranian culpability.  The Treasury Department did not immediately respond to a request for comment Monday about whether the sanctions designees were involved in those attacks, nor has the National Security Agency responded to requests for comment on whether Iran was responsible for attacks at the center of an alert about attacks on water facilities.

Treasury Secretary Scott Bessent announced a fuller list of sanctions Monday as the war with Iran nears its five-month anniversary with no end in apparent sight.

“In the Second World War, D-Day marked the historic beginning of a campaign with our allies to target and drive the enemy from its positions, including those in third countries,” he said. “Today, in that same spirit, we are launching an economic onslaught against Iran’s financial connections around the globe. Our objective is to sever every economic lifeline that sustains this tyrannical regime until Tehran stands alone.”

There are questions about whether the sanctions themselves are likely to change any behavior, particularly based on how they will be enforced. Iran has vowed “consequences” for the United States.

As part of the sanctions announced Monday, according to the department, “Treasury is expanding the categories of Iran-related conduct that may be subject to secondary sanctions in the future, making it easier to take action against those facilitating the regime. Treasury has issued determinations against five critical sectors –– digital assets, technology, gold, aviation, and shipping––  that the Iranian regime uses to try to prop up its failing economy.”

Hackers are targeting water, food, energy, chemical, manufacturing and commercial facilities by taking aim at Siemens S7 Series programmable logic controllers (PLCs) and making use of artificial intelligence in the attacks, U.S. government agencies warned Wednesday.

It’s the latest government warning about attacks on critical infrastructure as the United States wages war against Iran, which the government blamed for a recent campaign against water and wastewater systems— but doesn’t mention in Wednesday’s alert. 

The National Security Agency didn’t immediately respond to a request for comment about who was behind the attacks on the PLCs, which are used to control manufacturing processes.

The agencies said the attacks were an “active threat,” rather than a theoretical one. The attacks could disrupt critical industrial processes, cause safety incidents or lead to the compromise of sensitive data.

Wednesday’s alert from the NSA, Cybersecurity and Infrastructure Security Agency, FBI, Energy Department and Environmental Protection Agency makes special note of the hackers using AI-generated exploitation scripts in the attacks.

“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 exploitation scripts and malicious tools,” the alert states. “In addition, AI enables adversaries to rapidly leverage additional attack vectors and adapt to defensive measures. Threat actors can easily collect public information about vulnerabilities and weaknesses, find exposed and exploitable PLCs, and use AI-generated scripts to act on that information.”

A former top CISA official, Michael Garcia, thought that it was a first for the agency in one of its cybersecurity advisories (CSAs) about operational technology (OT).

“It is the first alert I have seen where CISA is saying in a CSA that a malicious actor is using AI scripts to target OT systems,” Garcia, now vice president of the cybersecurity practice at Monument Policy Advocacy, said on LinkedIn. But the advisory doesn’t recommend using AI in response, instead focusing on well-known, traditional defensive measures, he added.

Frenos, an OT penetration testing company, found another element of the alert troubling: The method by which the attackers could use the approach beyond Siemens-made PLCs.

“Siemens S7 is the subject here, but the exposure pattern is not brand specific,” Brian Proctor, CEO of the company, said in an email. “An adversary who has mapped your data blocks understands your process. They know what normal looks like, which means they know what an operator would fail to notice.”

The AI-generated scripts are disguised as legitimate monitoring tools, the advisory said of the hackers behind them.

“The actors leverage Internet scanning services to find Internet-exposed PLCs running outdated software or that are otherwise poorly protected,” the advisory reads.

Siemens said it was “aware” of the alert and “is coordinating closely with CISA.”

“This advisory does not describe new vulnerabilities within the S7 Series programmable logic controllers (PLC). Instead, this reflects threat actors employing new techniques to exploit potential misconfigurations,” the company continued, noting a security bulletin it issued last month.

“Siemens will provide updates around this issue to potentially affected customers through our ProductCERT team,” it said. “At this point in time, we have not identified increased attack levels or unknown vulnerabilities in Siemens ICS products.”

Federal authorities on Tuesday unsealed an indictment against 17 Iranians affiliated with the tech firm Mabna Institute, alleging a campaign of vast cybertheft on behalf of the Iranian government against universities, governments and companies.

It’s a second wave of indictments against the Tehran-based firm, expanding on and replacing a 2018 indictment of nine of the defendants from then and adding others. 

“Today’s charges, which include eight additional defendants, reveal the broader network allegedly behind a sweeping, state-sponsored campaign to steal research and intellectual property from American universities, businesses, and government institutions,” said Jamie McDonald, U.S. Attorney for the Southern District of New York. “More than eight years after making the original indictment public, these charges make clear that the passage of time will not deter us from identifying and pursuing those who target the United States from abroad.”

Unlike in 2018, the United States is currently waging a war against Iran that recently saw a 60-day negotiation deadline pass with no progress.

“Cyber operations have become a central instrument of national power, and attacks on American and allied institutions carry direct consequences for our security and economic strength,” McDonald continued.

According to the Justice Department, Gholamreza Rafatnejad and Ehsan Mohammadi founded the Mabna Institute around 2013 with the goal of helping Iranian universities and scientific and research organizations to steal from foreign scientific efforts. In doing so, it paid hackers-for-hire listed in the indictment.

The institute has compromised more than 100,000 professors’ email accounts globally, the indictment alleges, and successfully compromised 8,000 accounts at 144 U.S. universities and 178 universities in other parts of the world.

Its hackers used stolen credentials to take academic journals, dissertations and e-books across all fields of research, at least 31.5 terabytes worth in total. The institute sometimes sold stolen data, according to the indictment. 

“Through the course of the conspiracy, U.S.-based universities spent more than approximately $3.4 billion to procure and access such data and intellectual property,” a press release on the indictment states.

The defendants also have compromised and stolen from email accounts for at least five U.S. federal and state government agencies, 42 U.S. companies and 11 foreign companies, among them HBO. 

In all, the indictment brings 14 separate, sometimes overlapping charges against the 17 defendants, with sentences for each offense ranging from two to 20 years.

In conjunction with the indictment, the State Department’s Rewards for Justice program is offering up to $10 million for information leading to the location of four of the defendants.
