Massive cyberattack on Polish power system in December failed, minister says

The minister described the incident as the strongest attack on the energy infrastructure in years and noted that the event followed a different pattern from past assaults.

The article adds that Poland’s critical infrastructure has been subject to a growing number of cyberattacks by Russia since the war in Ukraine began in February 2022. Motyka’s remarks came as part of the country’s assessment of the December incident, which he characterised as a significant test to the resilience of the energy sector.
