The incident is reminiscent of the arson attack in Berlin, which was attributed to a far-left extremist group. This raises the question of the extent to which such groups act independently or possibly on the instructions of foreign actors, such as Russian intelligence services. Attacks on the power grid, in particular, are a typical element of hybrid warfare. European security agencies have been warning of such threats since last year, with Germany being a particular focus. However, it is difficult for investigative authorities to definitively attribute such acts.
With regard to the protection of critical infrastructure, the use of modern sensor technology could be helpful. While this would not prevent sabotage, it would facilitate both reconnaissance and damage repair. A prerequisite for this is closer cooperation and coordination between private operators of critical infrastructure and government agencies.
