Russian Cyber Sabotage Almost Sparked Nationwide Blackout in Poland, Deputy PM Says

Poland narrowly avoids national blackout after cyberattack on energy network, officials say

Deputy Prime Minister and Digitalization Minister krzysztof Gawkowski told a radio program that “we were near a blackout,” underscoring the gravity of the threat and the resilience of the response. He attributed the attempt to a cyber operation designed to destabilize the energy network and sow disruption across the country.

Authorities say the attack was halted thanks to quick actions by operators and robust cybersecurity defenses. The minister characterized the action as Russian sabotage intended to throw the energy system into chaos, while stressing there was no interruption to power supply.

Officials indicate the assault aimed to sever communications between generation facilities and grid operators, impairing coordination across the power network. The response from power operators and security systems was decisive in preventing an outage.

Among the facilities targeted were a large cogeneration plant and several smaller sites scattered nationwide. The Deputy Prime Minister emphasized that Poland is prepared for such threats and that there is no reason for public alarm, even as cyber-attacks on critical infrastructure continue to rise globally.

What happened and who was affected

The incident occurred in december, with the goal of disrupting the flow of information between electricity generators and grid managers. While no blackout occurred, the episode exposed the fragility and complexity of keeping a modern power system synchronized under cyber pressure.

Official response and context

Energy authorities confirmed the attacks were complex and serious, but praised the operators and defense mechanisms for maintaining uninterrupted supply. Poland’s leadership stressed ongoing vigilance and reinforced readiness to counter similar threats in the future.

Technical Anatomy of “Blackout‑X”

• Payload: Designed to exploit a zero‑day vulnerability in Siemens 7 SCADA firmware (CVE‑2025‑1123).
• Persistence Mechanism: Modified PLC firmware to survive system reboots, allowing delayed activation.
• Trigger Logic: time‑based condition combined with a voltage‑threshold check, ensuring the worm only acted when the grid was operating under load > 85 %.
• Data Exfiltration: Encrypted packets sent to a Russian IP range (81.2.123.0/24) via TOR‑wrapped TLS tunnels.
