According to CoinMeta, the Estonian Minister of Internal Affairs stated that Russia's aggressive actions in Europe should be regarded as "state-supported terrorism," rather than the so-called "hybrid attacks." Currently, European authorities are investigating the behind-the-scenes culprits of hacker attacks on supermarket freezers across Europe. Recently, a series of sabotage activities, arson incidents, and other acts intended to create unrest have occurred within Europe, all of which are believed to be related to Russia. The Estonian Minister of Internal Affairs said, "Using the term 'hybrid' to describe these actions is too mild. This is actually state-supported terrorism." He added, "Russia is the greatest challenge and threat that Europe faces. They have been continuously attacking Europe. Although these actions have not reached the threshold of military conflict, they are happening persistently." He further pointed out, "These are direct attacks on our critical infrastructure as well as military or defense-related targets."
