Russia's FSB blamed for Poland grid attack as UK and EU impose first joint cyber sanctions

Russia’s FSB, specifically its Center 16 signals intelligence arm, has been formally blamed for a cyberattack that threatened to cut heating to half a million people in Poland last winter. Following this attribution, the UK and EU have imposed coordinated sanctions targeting Russian cybercriminals, intelligence officers, and entities linked to the pro-Kremlin Rybar blog. These sanctions aim to disrupt Russia’s cyber ecosystem and its use of criminal networks to support espionage and disinformation campaigns. The attack highlighted Russia’s continued reliance on a broad cyber ecosystem to conduct malicious operations against Europe and its partners.
