Finnish Counterintelligence Chief Warns Russian Sabotage Threat to European Defense Industry Has Grown

BLUFRussian sabotage targeting European defense industry or Ukraine-aid logistics is very likely before year's end, though Finland itself faces elevated but not immediate risk.

Teemu Liikkanen, head of counterintelligence at Finland's Security and Intelligence Service (Supo), said on Yle's breakfast show on Monday that the threat of Russian sabotage in Europe has increased over the summer, and that the threat is real in Finland but shows no sign of being immediate 12. Yle reported that the defence industry and activities supporting Ukraine are the most vulnerable Finnish targets, and that Russian sabotage was noticeably quieter in 2025 1. Yle also reported that Russia is believed to have been behind last week's arson attack on a Starlink satellite station in Poland 1. Retired colonel Jyrki Isokangas told Yle that Moscow seeks to discourage Western support for Ukraine but does not, in his view, want a military challenge to NATO, and President Alexander Stubb has urged Finns to prepare mentally for possible sabotage 12.

Analysis
Finnish defence firms and Ukraine-aid logistics should plan for physical sabotage, though nothing suggests an attack on Finnish soil is imminent. A Russian-linked arson or disruption against a European defence-industrial or Ukraine-aid target is very likely by the end of 2026, given the rebound after a quiet 2025 and the Starlink station arson in Poland. An incident inside Finland in that window is unlikely, since Supo reports no immediate danger. The aim appears political: raising the cost of aiding Ukraine rather than provoking NATO. Confidence is low because the assessment rests on a single Yle report with no primary reporting behind it. Supo's warning may instead be preparing the public and industry for resilience measures, and 2025's quiet may reflect better Russian tradecraft or detection rather than restraint. A European defence-industrial incident by year-end would require Finnish and allied services and firms to fund physical security and counterintelligence. Absent one, current posture can hold.
