Sandworm Accused of Cyberattack on Poland’s Power Grid
Polish authorities and reporting tied to ESET research attributed a disruptive cyber incident affecting Poland’s electricity grid to Russia-linked threat actors, with Sandworm named as the likely operator behind the operation in late 2025. The incident was characterized as a targeted attack on critical infrastructure, reinforcing ongoing concerns about state-aligned activity against European energy networks.
A separate malware-newsletter roundup recirculated the attribution as one of many items, while an unrelated CSO Online feature focused on forward-looking CISO predictions for 2026 and did not provide incident-specific details. Executive teams should treat the Poland grid activity as part of the broader pattern of Russian state-linked operations against OT/ICS environments, with emphasis on validating segmentation, monitoring for lateral movement into OT, and ensuring incident response playbooks cover grid/industrial disruption scenarios.

Sandworm-Linked DynoWiper Used in Failed Attack on Poland’s Energy Infrastructure
Polish officials reported a **failed late-December cyberattack** targeting the country’s energy infrastructure, described by Energy Minister Milosz Motyka as the “strongest attack” on the sector in years. The activity on December 29–30 targeted **two combined heat and power (CHP) plants** and attempted to disrupt systems and communications supporting electricity management from **renewable sources** (including wind and photovoltaic installations) and their links to power distribution operators; local reporting indicated the impact could have been significant if successful. Security firm **ESET** said the attempted disruptive operation involved a previously undocumented **wiper** malware it named **DynoWiper**, designed to irreversibly destroy data and render systems inoperable. ESET attributed the activity with **medium confidence** to **Sandworm** (a GRU-linked threat actor) based on overlaps with prior Sandworm-associated destructive campaigns, particularly against Ukraine’s energy sector; Polish leadership publicly blamed Russia-linked groups and indicated additional safeguards and cybersecurity legislation were being prepared to strengthen IT/OT risk management and incident response. Both reporting noted the timing was close to the **10-year anniversary** of Sandworm’s 2015 attacks on Ukraine’s power grid.

Destructive Cyberattack on Poland’s Energy Sector via Vulnerable Edge Devices
Poland’s Computer Emergency Response Team reported that a **destructive cyber incident** in December 2025 compromised **OT/ICS environments** across the country’s energy sector, including **renewable energy plants** (wind and photovoltaic), a **combined heat and power** facility, and at least one **manufacturing** organization. The intrusion reportedly began through **vulnerable internet-facing edge devices**, after which the actor deployed **wiper malware** that damaged **remote terminal units (RTUs)**, destroyed data on **human-machine interfaces (HMIs)**, and **corrupted firmware** on OT devices—resulting in a loss of operator “view and control” even where renewable generation continued producing power but could not be monitored or controlled as designed. Reporting indicated the activity overlapped with infrastructure associated with a **Russian government-linked** hacking group. CISA issued an alert to U.S. critical infrastructure organizations to amplify the Polish findings and emphasize mitigations for **energy-sector OT/ICS** defenders, highlighting the ongoing risk from **end-of-support edge devices** and the need to harden remote access paths, credential hygiene (including **default credentials**), and incident response planning for scenarios where OT devices may become inoperable or permanently damaged due to firmware corruption. Separate industry commentary and a Dark Reading article provided broader context on the evolution of OT threats (e.g., lessons from Ukraine’s 2015 grid attack and emerging “living-off-the-plant” techniques), but did not add incident-specific details about the Poland event beyond reinforcing the general trend of increasing attacker capability and interest in industrial environments.

Poland Repels Suspected Russia-Linked Cyberattack Targeting Renewable Energy Grid Communications
Polish officials reported thwarting what they described as the most serious cyberattack on the country’s energy infrastructure in years, saying the intrusion came close to causing a widespread power outage. The attempted disruption occurred in the final days of December and targeted communications links between multiple renewable energy installations—such as **solar farms** and **wind turbines**—and electricity distribution operators across large parts of Poland, in what authorities characterized as a coordinated sabotage effort. Digital Affairs Minister Krzysztof Gawkowski said the incident “very close to a blackout” appeared to be a deliberate attempt to cut power to Polish citizens and that “everything points to Russian sabotage,” though officials did not provide technical details, name a specific threat actor, or disclose the defensive measures implemented afterward. The incident reflects a broader pattern of increased Russia-linked cyber activity against Polish critical infrastructure since Russia’s 2022 invasion of Ukraine, alongside ongoing kinetic strikes on Ukraine’s energy system that Ukrainian authorities have described as creating an “unprecedented” energy crisis.
