Researchers say Russian government hackers were behind attempted Poland power outage
Security researchers have attributed the attempted use of destructive "wiper" malware across Poland's energy infrastructure in late December to a Russian-backed hacking group known for causing power outages in neighboring Ukraine.
TL;DR
- A December cyberattack on Poland's energy grid was attributed to Russian government hackers.
- The attack targeted two heat and power plants and communication links for renewable energy installations.
- Cybersecurity firm ESET identified the malware as DynoWiper and linked it to the Sandworm hacking group.
- Sandworm is associated with Russia's military intelligence agency GRU and has previously targeted Ukraine's energy sector.
- Polish officials stated that critical infrastructure was not threatened due to successful cybersecurity defenses.
