As Russia has tested every form of attack on Ukraine's civilians over the past decade, both digital and physical, it's often used winter as one of its weapons—launching cyberattacks on electric utilities to trigger December blackouts and ruthlessly bombing heating infrastructure. Now it appears Russia-based hackers last January tried yet another approach to leave Ukrainians in the cold: a specimen of malicious software that, for the first time, allowed hackers to reach directly into a Ukrainian heating utility, switching off heat and hot water to hundreds of buildings in the midst of a winter freeze.

Industrial cybersecurity firm Dragos on Tuesday revealed a newly discovered sample of Russia-linked malware that it believes was used in a cyberattack in late January to target a heating utility in Lviv, Ukraine, disabling service to 600 buildings for around 48 hours. The attack, in which the malware altered temperature readings to trick control systems into cooling the hot water running through buildings' pipes, marks the first confirmed case in which hackers have directly sabotaged a heating utility.

Dragos' report on the malware notes that the attack occurred at a moment when Lviv was experiencing its typical January freeze, close to the coldest time of the year in the region, and that “the civilian population had to endure sub-zero [Celsius] temperatures.” As Dragos analyst Kyle O'Meara puts it more bluntly: “It's a shitty thing for someone to turn off your heat in the middle of winter.”

The malware, which Dragos is calling FrostyGoop, represents one of less than 10 specimens of code ever discovered in the wild that's designed to interact directly with industrial control-system software with the aim of having physical effects. It's also the first malware ever discovered that attempts to carry out those effects by sending commands via Modbus, a commonly used and relatively insecure protocol designed for communicating with industrial technology.

Dragos first discovered the FrostyGoop malware in April after it was uploaded in several forms to an online malware scanning service—most likely the Google-owned scanning service and malware repository VirusTotal, though Dragos declined to confirm which service—perhaps by the malware's creators, in an attempt to test whether it was detected by antivirus systems. Working with Ukraine's Cyber Security Situation Center, a part of the country's SBU cybersecurity and intelligence agency, Dragos says it then learned that the malware had been used in the cyberattack that targeted a heating utility starting on January 22 in Lviv, the largest city in western Ukraine.

Dragos declined to name the victim utility, and in fact says it hasn't independently confirmed the the utility's name, since it only became aware of the targeting from the Ukrainian government. Dragos' description of the attack, however, closely matches reports of a heating outage at the Lvivteploenergo utility around the same time, which according to local media led to a loss of heating and hot water for close to 100,000 people.

Lviv mayor Andriy Sadovyi at the time called the event a “malfunction" in a post to the messaging service Telegram, but added, “there is a suspicion of external interference in the company's work system, this information is currently being checked.” A Lvivteploenergo statement on January 23 described the outage more conclusively as the “result of a hacker attack.”

Lvivteploenergo didn't respond to WIRED's request for comment, nor did the SBU. Ukraine's cybersecurity agency, the State Services for Special Communication and Information Protection, declined to comment.

In its breakdown of the heating utility attack, Dragos says that the FrostyGoop malware was used to target ENCO control devices—Modbus-enabled industrial monitoring tools sold by the Lithuanian firm Axis Industries—and change their temperature outputs to turn off the flow of hot water. Dragos says that the hackers had actually gained access to the network months before the attack, in April 2023, by exploiting a vulnerable MikroTik router as an entry point. They then set up their own VPN connection into the network, which connected back to IP addresses in Moscow.

Despite that Russia connection, Dragos says it hasn't tied the heating utility intrusion to any known hacker group it tracks. Dragos noted in particular that it hasn't, for instance, tied the hacking to the usual suspects such as Kamacite or Electrum, Dragos' own internal names for groups more widely referred to collectively as Sandworm, a notorious unit of Russia's military intelligence agency, the GRU.

Dragos found that, while the hackers used their breach of the heating utility's network to send FrostyGoop's Modbus commands that targeted the ENCO devices and crippled the utility's service, the malware appears to have been hosted on the hackers' own computer, not on the victim's network. That means simple antivirus alone, rather than network monitoring and segmentation to protect vulnerable Modbus devices, likely won't prevent future use of the tool, warns Dragos analyst Mark “Magpie” Graham. “The fact that it can interact with devices remotely means it doesn't necessarily need to be deployed to a target environment,” Graham says. “You may potentially never see it in the environment, only its effects.”

While the ENCO devices in the Lviv heating utility were targeted from within the network, Dragos also warns that the earlier version of FrostyGoop it found was configured to target an ENCO device that was instead publicly accessible over the open internet. In its own scans, Dragos says it found at least 40 such ENCO devices that were similarly left vulnerable online. The company warns that there may in fact be tens of thousands of other Modbus-enabled devices connected to the internet that could potentially be targeted in the same way. “We think that FrostyGoop would be able to interact with a huge number of these devices, and we're in the process of conducting research to verify which devices would indeed be vulnerable,” Graham says.

While Dragos hasn't officially linked the Lviv attack to the Russian government, Graham himself doesn't shy away from describing the attack as a part of Russia's war against the country—a war that has brutally decimated Ukrainian critical infrastructure with bombs since 2022 and with cyberattacks starting far earlier, since 2014. He argues that the digital targeting of heating infrastructure in the midst of Ukraine's winter may actually be a sign that Ukrainians' increasing ability to shoot down Russian missiles has pushed Russia back to hacking-based sabotage, particularly in western Ukraine. “Cyber may actually be more efficient or likely to be successful towards a city over there, while kinetic weapons are maybe still successful at a closer range," Graham says. “They’re trying to use the full spectrum, the full gamut of available tools in the armory.”

Even as those tools evolve, though, Graham describes the hackers' goals in terms that have changed little in Russia's decade-long history of terrorizing its neighbor: psychological warfare aimed at undermining Ukraine's will to resist. “This is how you chip away at the will of the people,” says Graham. “It wasn’t aimed at disrupting the heating for all of winter. But enough to make people to think, is this the right move? Do we continue to fight?”

Precision Redefined – PLC-Controlled Shock Absorber Testing Machines

Precision – a word that keeps on getting thrown around often in the world of engineering. However, when it comes to shock absorber testing, precision isn’t a luxury—it’s survival. Every curve, every jolt, every rebound of a shock absorber must be captured, tested, and analysed to microscopic exactness. Gone are the days when manual testing could keep up.

The role of shock absorbers in today’s high-speed automotive innovation and precision engineering is to provide safety, comfort, and performance protection. But how can we make sure that these absorbers meet the high standards required by modern vehicles? This is where PLC automation becomes a useful tool.

The old-fashioned testing methods, which were cumbersome, unreliable, and laborious, have been replaced by PLC-based automation systems. Imagine a testing line with the capacity to think, adapt and respond in real time. The precision of Programmable Logic Controllers (PLCs) is not solely a promise, but rather adherence to standardised protocols. 

How PLCs Enhance Shock Absorber Testing

There has been an evolution in the science of testing shock absorbers. Let’s understand how smart and compact PLCs can automate and optimise critical testing stages by providing consistency, control, and clarity. 

Centralised Control with High Reliability

A robust industrial PLC is the foundation of our testing machines. The real-time control systems embedded in our automation design enable seamless functioning of all sensor, actuator, and motorised components. 

Multiple sensors? Check. 

Complex test sequences? Seamlessly handled. 

From servo motion controllers managing high-speed vertical displacements to compact PLCs managing individual test stations, the formation is digital, deliberate, and dependable.

Real-Time Data Acquisition & Analysis

Here's where things get exciting. Tests on shock absorbers are more than just passing or failing. It's about quantifiable performance with our automation controllers: 

Damping force curves

Displacement maps

Velocity and resistance profiles. 

The data is gathered by high-resolution sensors and then processed through HMI with PLC controllers. The integration of this with databases is achieved through integrated PLC-based software, resulting in predictive maintenance and long-term performance insights

Feedback Loops for Adaptive Control

Ever wondered what would happen if the test differs? What would be the outcome? Well, with the use of real-time PLC communication protocols (like MODBUS and Ethernet/IP) and closed-loop control enable our systems to identify anomalies mid-test while enabling automatic correction.

Additionally, dynamic adjustment of actuator velocity in a system is possible when the response rate of the unit is slower than the tolerance. Or if temperatures spike? After a system shutdown, it sends an alert via the web server PLC and logs the fault. This requires more than just testing -- intelligent testing.

NX-ERA JET PLC System Architecture

Now let’s explore the engine room that fuels our innovation. The NX-ERA JET PLC, the foundation of our automated testing platform, undergoes a thorough architecture and connectivity analysis. 

Core Hardware Components

With its compact size, modular design, and future scalability, the NX-ERA JET PLC is a formidable beast. It houses:
