Poland’s energy grid was targeted by never-before-seen wiper malware

Researchers on Friday said that Poland’s electric grid was targeted by wiper malware, likely unleashed by Russia state hackers, in an attempt to disrupt electricity delivery operations.

A cyberattack, Reuters reported, occurred during the last week of December. The news organization said it was aimed at disrupting communications between renewable installations and the power distribution operators but failed for reasons not explained.

Wipers R Us

On Friday, security firm ESET said the malware responsible was a wiper, a type of malware that permanently erases code and data stored on servers with the goal of destroying operations completely. After studying the tactics, techniques, and procedures (TTPs) used in the attack, company researchers said the wiper was likely the work of a Russian government hacker group tracked under the name Sandworm.

“Based on our analysis of the malware and associated TTPs, we attribute the attack to the Russia-aligned Sandworm APT with medium confidence due to a strong overlap with numerous previous Sandworm wiper activity we analyzed,” said ESET researchers. “We’re not aware of any successful disruption occurring as a result of this attack.”

Sandworm has a long history of destructive attacks waged on behalf of the Kremlin and aimed at adversaries. Most notable was one in Ukraine in December 2015. It left roughly 230,000 people without electricity for about six hours during one of the coldest months of the year. The hackers used general purpose malware known as BlackEnergy to penetrate power companies’ supervisory control and data acquisition systems and, from there, activate legitimate functionality to stop electricity distribution. The incident was the first known malware-facilitated blackout.

Microsoft vows to cover full power costs for energy-hungry AI data centers

Taking responsibility for power usage

In the Microsoft blog post, Smith acknowledged that residential electricity rates have recently risen in dozens of states, driven partly by inflation, supply chain constraints, and grid upgrades. He wrote that communities “value new jobs and property tax revenue, but not if they come with higher power bills or tighter water supplies.”

Microsoft says it will ask utilities and public commissions to set rates high enough to cover the full electricity costs for its data centers, including infrastructure additions. In Wisconsin, the company is supporting a new rate structure that would charge “Very Large Customers,” including data centers, the cost of the electricity required to serve them.

Smith wrote that while some have suggested the public should help pay for the added electricity needed for AI, Microsoft disagrees. He stated, “Especially when tech companies are so profitable, we believe that it’s both unfair and politically unrealistic for our industry to ask the public to shoulder added electricity costs for AI.”

On water usage for cooling, Microsoft plans a 40 percent improvement in data center water-use intensity by 2030. A recent environmental audit from AI model-maker Mistral found that training and running its Large 2 model over 18 months produced 20.4 kilotons of CO2 emissions and evaporated enough water to fill 112 Olympic-size swimming pools, illustrating the aggregate environmental impact of AI operations at scale.

To solve some of these issues, Microsoft says it has launched a new AI data center design using a closed-loop system that constantly recirculates cooling liquid, dramatically cutting water usage. In this design, already deployed in Wisconsin and Georgia, potable water is no longer needed for cooling.

On property taxes, Smith stated in the blog post that the company will not ask local municipalities to reduce their rates. The company says it will pay its full share of local property taxes. Smith wrote that Microsoft’s goal is to bring these commitments to life in the first half of 2026. Of course, these are PR-aligned company goals and not realities yet, so we’ll have to check back in later to see whether Microsoft has been following through on its promises.

Spanish blackout report: Power plants meant to stabilize voltage didn’t

electricity, Energy, grid stability, Portugal, Science, spain / /

The blackout that took down the Iberian grid serving Spain and Portugal in April was the result of a number of smaller interacting problems, according to an investigation by the Spanish government. The report concludes that several steps meant to address a small instability made matters worse, eventually leading to a self-reinforcing cascade where high voltages caused power plants to drop off the grid, thereby increasing the voltage further. Critically, the report suggests that the Spanish grid operator had an unusually low number of plants on call to stabilize matters, and some of the ones it did have responded poorly.

The full report will be available later today; however, the government released a summary ahead of its release. The document includes a timeline of the events that triggered the blackout, as well as an analysis of why grid management failed to keep it in check. It also notes that a parallel investigation checked for indications of a cyberattack and found none.

Oscillations and a cascade

The document notes that for several days prior to the blackout, the Iberian grid had been experiencing voltage fluctuations—products of a mismatch between supply and demand—that had been managed without incident. These continued through the morning of April 28 until shortly after noon, when an unusual frequency oscillation occurred. This oscillation has been traced back to a single facility on the grid, but the report doesn’t identify it or even indicate its type, simply referring to it as an “instalación.”

The grid operators responded in a way that suppressed the oscillations but increased the voltages on the grid. About 15 minutes later, a weakened version of this oscillation occurred again, followed shortly thereafter by oscillations at a different frequency, this one with properties that are commonly seen on European grids. That prompted the grid operators to take corrective steps again, which increased the voltages on the grid.

The Iberian grid is capable of handling this sort of thing. But the grid operator only scheduled 10 power plants to handle voltage regulation on the 28th, which the report notes is the lowest total it had committed to in all of 2025 up to that point. The report found that a number of those plants failed to respond properly to the grid operators, and a few even responded in a way that contributed to the surging voltages.
