Coordinated Wiper Attacks Hit 30+ Renewable Farms, Sparking Grid Security Concerns

CERT Polska disclosed a coordinated, destructive cyber campaign on Dec 29, 2025 that hit more than 30 wind/solar farms and a CHP plant, disrupting substation communications but not stopping electricity or heat delivery. The attackers deployed wipers (DynoWiper, LazyWiper) via compromised Fortinet devices and Active Directory, used multiple accounts with no two-factor authentication, and leveraged Tor/IPs to access energy networks, with several variants and likely LLM involvement; data was also exfiltrated from OT/cloud services. Attribution to Static Tundra tied to Russia's FSB is stated by CERT Polska, though some researchers link activity to Sandworm.

Russia-linked wiper targets Poland’s grid but power stays on

Poland’s electric grid was targeted by a new wiper malware, allegedly from Russia’s Sandworm group, on the late-December anniversary of a Ukraine grid attack. The payload, dubbed DynoWiper, aimed to disrupt communications between renewables and grid operators but did not cause a blackout. Attribution is at medium confidence and researchers say there’s no evidence of disruption, with several possible reasons the attack failed.

Russia-Linked Wiper Attack on Poland’s Power Grid Foiled

European security firm ESET says a December attack on Poland’s energy sector used a destructive wiper called DynoWiper with the aim of causing outages; the attack was blocked before any power was cut, though it could have affected up to about 500,000 people. Authorities attribute the operation to Russia’s Sandworm/GRU, marking a notable disruptive cyber threat against Poland’s energy infrastructure and underscoring the risk of wiper campaigns.

"Russian Hackers Employ LOTL Technique for Power Outage Attacks"

Russian state hackers known as Sandworm have adopted living-off-the-land (LOTL) techniques to breach industrial control systems (ICS) more efficiently and with less detectable malware. In a recent attack on a Ukrainian critical infrastructure organization, Sandworm used a native binary to send commands to the SCADA system, resulting in a power outage. The hackers also deployed data-destroying malware to further disrupt the environment. Security researchers believe that Sandworm's shift to LOTL techniques and their ability to recognize new OT threat vectors indicate a growing maturity in Russia's offensive OT arsenal, making them capable of carrying out attacks against OT systems from different vendors.
