Ransomware, Lack of Visibility, Mischaracterizations and Nation-States, Oh My
There’s a silent epidemic of ransomware assaults on industrial operational expertise techniques, that are mischaracterized as IT incidents though they impression operational techniques, claims a complete annual evaluate of cyberattacks focusing on OT, revealed this week by safety agency Dragos.

The report outlines worrying tendencies within the actions of nation-state stage OT hacker teams, that are more and more transferring from preliminary entry efforts to operations designed to reconnoiter OT techniques and pre-position for assaults with actual world results.
Knowledge collected by Dragos discovered ransomware assaults on OT techniques are routinely mischaracterized, founder and CEO Rob Lee advised reporters. “It is exhausting to estimate the share, however lots of these [OT ransomware] circumstances are getting misidentified” as IT incidents, he stated at a web based press occasion to launch the report.
He blamed IT cybersecurity groups who do not perceive how OT techniques work, and the truth that most companies do not accumulate the OT community knowledge wanted to do root trigger evaluation of cyberattacks on OT techniques.
“I’ve personally been concerned in various [ransomware incident response] circumstances the place there was bodily injury or [OT] outages and there was no knowledge accessible collected forward of time to have the ability to decide if cyber was a element in that or not,” Lee stated.
With out knowledge to know for certain whether or not or not OT techniques had been cyber attacked, not to mention how efficiently, corporations usually selected to go along with a public narrative that wrote the incident off as a standard IT ransomware an infection which “impacted” – in some non-specific approach – their operations.
Dragos tracked 119 ransomware teams focusing on industrial organizations in 2025, a 49% improve from 80 such assaults in 2024, states the report. The corporate recognized 3,318 assaults on industrial organizations, stated Lee, noting that the precise quantity was doubtless increased, as many incidents go unreported or undetected.
“I take into account [the Dragos annual report] necessary studying for anybody working in OT/ICS, for anybody defending OT/ICS from cyberattacks,” stated Mike Holcomb, an unbiased cybersecurity marketing consultant specializing in OT/ICS. Holcomb was till final November the OT/ICS cybersecurity international lead for Fluor, one of many world’s largest engineering and building corporations.
A Decade After Stuxnet, Visibility Is Nonetheless The Predominant Drawback
The US-Israeli Stuxnet cyber weapon a decade in the past employed extremely refined OT-specific malware to destroy industrial tools – centrifuges used to complement uranium.
“The huge, overwhelming majority of asset house owners and operators at this time nonetheless couldn’t detect the ways, methods, the methodology of what Stuxnet did 10 years in the past,” stated Lee. Not like IT networks, the place visitors is extensively logged, visitors on OT networks tends to be ephemeral. Until particularly copied and saved, it’s unavailable for subsequent forensic evaluation. But solely 5% to 10% of asset operators have that visibility at this time, Lee stated (see: For OT Cyber Defenders, Lack of Knowledge Is the Greatest Risk).
“We will solely report on issues the place we’ve knowledge for,” stated Lee, so lots of the main focus within the report ended up being on corporations with high-end defenses, similar to massive electrical energy utilities, as a result of they had been in a position to detect and observe intrusions into their OT networks.
“There’s not lots of dialogue right here on Brazilian-based mining corporations,” Lee stated, as a result of they, like most corporations, lack the potential to detect intrusions into their OT networks. “So they don’t seem to be seeing something to have the ability to report … They do not know what is going on on of their networks.”
Recognition of the visibility drawback is rising amongst OT house owners and operators, stated Mark Cristiano, international industrial director for cybersecurity providers at Rockwell Automation, a significant OT techniques vendor, and a Dragos accomplice. “There’s simply extra consciousness on the CISO stage of the significance and the complexity of defending OT,” Cristiano advised Data Safety Media Group in an earlier interview.
“The questions which can be being requested now are from a way more knowledgeable place, from a few of these leaders that we discuss to.” He stated that rising consciousness is pushed by a number of components, together with information tales and warnings from authorities officers about nation-state assaults on the ability grid and different important infrastructure, and by regulatory modifications just like the Cyber Incident Reporting for Essential Infrastructure Act of 2022.
However whereas rules could also be driving curiosity and dialog, their impression on safety is much less clear and prone to take years. The U.S. Cybersecurity and Infrastructure Safety Company is planning a slew of city halls this spring with a evaluate agenda that seems poised to place off a ultimate rule previous the its anticipated Could rollout.
A unique set of latest rules for the majority electrical energy system in North America would require OT community monitoring for key websites within the energy grid, Lee stated. However, he famous that, following consultations with trade, they may also be phased in over three to 5 years (see: Monitoring the Electrical Grid Is Simpler Mentioned Than Achieved).
It is Not an OT Assault If We Say It Wasn’t
Even when assaults had been detected, they had been usually mischaracterized, Lee stated, citing ransomware assaults on manufacturing vegetation that immediately affected operations by encrypting knowledge on the servers and digital machines that related OT depends on, or on the workstations utilized by engineers to regulate OT techniques. Lee stated such assaults had been usually outlined as “IT incidents” as a result of they impacted an endpoint or a server working the Home windows working system.
A separate report, revealed by Dragos final 12 months, however written by analysts from insurance coverage big Marsh McLennan utilizing their knowledge, supplied proof of misidentification, stated Lee. The report correlated insurance coverage declare knowledge from assaults described as IT-only, exhibiting that in lots of circumstances “folks had been saying it was simply an IT incident, however had been truly submitting property injury claims on the operations aspect of the home,” stated Lee. He added that this urged there’s “tens of billions of {dollars} in impression yearly that’s getting mischaracterized, misclassified and threat that wasn’t getting lined beneath the best insurance policies.”
Like ransomware attackers on the whole, hackers focusing on industrial organizations usually abuse identification, stealing passwords and authentication credentials that allowed them to log in to belongings immediately related to OT techniques. The menace group Dragos designates TAT25-84, additionally tracked as Scattered Lapsus Shiny Hunters, was a great instance of attackers abusing identification on this approach. “The group systematically exploited help-desk workflows, self-service password reset mechanisms and MFA enrollment to achieve privileged entry” to techniques internet hosting or related to OT.
“These campaigns required no specialised exploits and infrequently prevented detection solely till important enterprise techniques underpinning OT continuity similar to ERP, virtualization, cloud SaaS platforms, or backup infrastructure, had been degraded or unavailable,” notes the report. Typical ransomware, executed on a hypervisor internet hosting SCADA, human-machine interface software program or engineering workloads, encrypts or corrupts knowledge and “routinely resulted in denial of view, denial of management, and multi-day lack of productiveness and income, even with none interplay with industrial protocols.”
The report cautions that ransomware actors usually exaggerate or make false claims about their OT capabilities. Dragos “noticed a number of ransomware operators and hybrid hacktivist personas making an attempt to inflate their perceived capabilities by misrepresenting entry to industrial techniques.” One extremely public incident concerned ransomware group Devman publishing screenshots of OT management consoles and monitoring dashboards, “falsely claiming to have developed ‘ICS-aware ransomware.’ Dragos evaluation discovered no proof supporting these assertions and no indication Devman accessed or might work together with ICS tools.”
Regardless of the absence of technical proof for such claims, the report notes that they “created uncertainty for victims, launched friction into government decision-making and attracted media amplification, … [allowing] adversaries to artificially improve extortion stress.”
A Dire Warning
The report additionally paperwork a shift in high-end cyberattacks towards OT techniques, with extra intrusions designed to pre-position adversaries “contained in the management loop,” from the place they will concern instructions to industrial or energy transmission or technology techniques. Lee, drawing on his personal expertise working U.S. offensive cyber operations, stated this was attribute of a unit making ready the battlefield for a battle.
“The shift is from ‘I need entry that could possibly be used for a future assault,’ to ‘I need to get entry and explicitly begin doing the actions to arrange my capability to do the assault,” Lee stated, “That is what shifted this previous 12 months.”
“An inexpensive evaluation” of this shift was that operators had been being advised to arrange for offensive cyber-physical operations inside 12 months, stated Lee. “They … are being advised by their management, ‘You understand what? It is not nearly getting entry. We would need to leverage that entry inside a 12 month interval.’ And while you hear that as an offensive workforce, that is while you go forward and develop that [control loop access] out,” he stated.
Even the place knowledge was being stolen, he stated, it was being completed to conduct reconnaissance on the techniques and perceive how they labored – and the way they could possibly be disrupted. “Nothing that they had been taking was helpful for mental property, the whole lot they had been doing and studying was solely helpful for disrupting or inflicting destruction at these websites,” he stated, calling it “a really clear sign,” that attackers had been “embedding in that infrastructure for the aim of taking it down.”
