The Scale of Russian Sabotage Operations Against Europe’s Critical Infrastructure

Charlie Edwards

Russia is waging an unconventional war on Europe. Through its campaign of sabotage, vandalism, espionage and covert action, Russia’s aim has been to destabilise European governments, undermine public support for Ukraine by imposing social and economic costs on Europe, and weaken the collective ability of NATO and the European Union to respond to Russian aggression. This unconventional war began to escalate in 2022 in parallel to Russia’s invasion of Ukraine. While Russia has so far failed to achieve its primary aim, European capitals have struggled to respond to Russian sabotage operations and have found it challenging to agree a unified response, coordinate action, develop effective deterrence measures and impose sufficient costs on the Kremlin.

IISS has created the most comprehensive open-source database of suspected and confirmed Russian sabotage operations targeting Europe. The data reveals Russian sabotage has been aimed at Europe’s critical infrastructure, is decentralised and, despite European security and intelligence officials raising the alarm, is largely unaffected by NATO, EU and member state responses to date. Russia has exploited gaps in legal systems through its ‘gig economy’ approach, enabling it to avoid attribution and responsibility. Since 2022 and the expulsion of hundreds of its intelligence officers from European capitals, Russia has been highly effective in its online recruitment of third-country nationals to circumvent European counter-intelligence measures. While the tactic has proven successful in terms of reach and volume, enabling operations at scale, the key challenge facing the Russian intelligence services has been the quality of the proxies, who are often poorly trained or ill-equipped, making their activities prone to detection, disruption or failure.

Russia’s military doctrine deeply integrates Critical National Infrastructure (CNI) sabotage within gibridnaya voyna (hybrid warfare). Europe’s critical infrastructure is particularly vulnerable to sabotage because it is in such a poor state following decades of deferred maintenance and a lack of investment from national governments and the private sector. Russia has targeted critical infrastructure to generate direct strategic gain in its war in Ukraine and as part of its broader conflict with the West. While some initiatives, such as the Baltic Sentry NATO maritime operation in the Baltic Sea, have been somewhat effective, the lack of budget and resources has kept NATO and the EU from adopting a long-term and sustained response. Furthermore, it is unclear, faced with competing national security priorities, how committed European capitals are to deterring Russia’s unconventional war on Europe.
