Russian hackers attack Slovak governmental websites after Slovakia sends MiG-29 jets to Ukraine.

Slovakia experienced a coordinated cyberattack on several of its key state-websites, including those of the National Council (parliament), the National Bank and the Ministry of Defence. According to the report, the attack followed Slovakia’s decision to transfer its first MiG-29 fighter jets to Ukraine, a move that evidently triggered Russian-linked hackers to issue warnings directed at the Slovak government. The malicious actors—self-identified as “Anonymous RU”—claimed responsibility and sent messages demanding that Slovakia cease its military assistance to Ukraine. The type of attack was reported as a DDoS-style broadcast flood aimed at overwhelming server-capacity and rendering the websites inaccessible for hours, though no definitive data exfiltration or sabotage of physical systems was made public. The geography of the incident spans Slovakia’s national capital region and central government infrastructure, showing that even interior, non-border-zones are within reach of hybrid-threat operations. While it did not directly damage industrial infrastructure or involve airspace/maritime penetration, it underscores how the Slovakia is subject to hybrid-warfare tactics executed by the Russian Federation (or its proxies) whereby cyber disruption is used to influence allied policy and impose costs.
