Finnish intelligence warns companies of ongoing Russian cyber espionage targeting corporate network devices, backed by joint Western advisory and European Council accusations against Russia's FSB.

The Finnish Security Intelligence Service (Supo) and Finnish Defence Intelligence Agency warn companies about an ongoing Russian cyber espionage campaign targeting vulnerable corporate network infrastructure devices. This campaign exploits poorly protected network equipment rather than home internet routers. The warning aligns with a joint advisory issued by the US NSA and Western intelligence services, highlighting persistent exploitation by Russian state-backed hackers. The European Council accuses Russia's FSB of sustained cyber activity against the EU and partners, including infiltration of government networks and critical infrastructure sabotage. Finnish Foreign Minister Elina Valtonen has summoned Russia's ambassador to Finland in protest.
