Poland's Energy Sector Thwarts Major Cyberattack by Sandworm Group
Executive Summary
In late December 2025, Poland's energy infrastructure was targeted by a coordinated cyberattack involving the deployment of a new data-wiping malware named DynoWiper. The attack focused on over 30 wind and solar farms, a combined heat and power plant serving nearly half a million customers, and a manufacturing company. The attackers exploited exposed FortiGate devices lacking multi-factor authentication to gain initial access, then moved laterally within networks to deploy the wiper malware. Despite the sophisticated nature of the attack, endpoint detection and response systems successfully blocked the malware's execution, preventing any disruption to energy production or distribution.

This incident underscores the escalating threat posed by state-sponsored cyber actors targeting critical infrastructure. The use of destructive malware like DynoWiper highlights the need for robust cybersecurity measures, including the implementation of multi-factor authentication and regular security audits, to protect against such sophisticated attacks.

Why This Matters Now
The recent attack on Poland's energy sector demonstrates the increasing sophistication and boldness of state-sponsored cyber threats targeting critical infrastructure. As geopolitical tensions rise, the likelihood of similar attacks on energy systems worldwide grows, emphasizing the urgent need for enhanced cybersecurity protocols and international cooperation to safeguard essential services.
Attack Path Analysis
The adversary exploited exposed VPN interfaces on FortiGate devices lacking multi-factor authentication to gain initial access. They escalated privileges by modifying device settings to maintain persistence and gain administrative access within the Windows domain. Lateral movement was achieved through credential theft and internal reconnaissance, allowing deployment of wiper malware across operational technology (OT) and information technology (IT) systems. Command and control were established via compromised systems, enabling the execution of destructive payloads. While exfiltration was not the primary goal, preparatory activities included data theft preceding the destructive phases. The impact involved deploying custom wipers like DynoWiper and LazyWiper to disrupt operations and cause data loss, though energy generation continued unaffected.

Sector Implications
Industry-specific impact of the vulnerabilities, including operational, regulatory, and cloud security risks.
Oil/Energy/Solar/Greentech
Direct target of Russia-aligned wiper attacks on renewable infrastructure requires enhanced east-west traffic security and egress filtering to prevent lateral movement and data exfiltration.
Utilities
Critical infrastructure vulnerability to nation-state wipers demands zero trust segmentation and multicloud visibility to protect heating, power plants from encrypted traffic exploitation and anomaly detection.
Government Administration
Geopolitical cyber warfare targeting energy sectors necessitates threat detection capabilities and secure hybrid connectivity to meet NIST compliance requirements against sophisticated state-sponsored attacks.
Defense/Space
National security implications from energy infrastructure attacks require inline IPS and cloud native security fabric to counter advanced persistent threats and protect critical systems.
