Cyber Incident Victim: National Council of the Slovak Republic

The National Security Office of Slovakia (NBU) detected a series of coordinated cyber incidents targeting Slovakia's cyber infrastructure in early January 2023. These attacks, attributed to the Russian threat group anonymous.ru (Anonymous Russia), employed distributed denial-of-service (DDoS) techniques designed to disrupt service availability. The NBU publicly confirmed the incidents on January 13, 2023, issuing a formal warning about potential follow-on attacks while withholding technical specifics about the targeted systems. The agency declined to disclose whether parliamentary operations were directly impacted, though the timing coincided with heightened regional tensions. Security officials characterized the campaign as demonstrating increased coordination among threat actors targeting Slovak digital infrastructure.

The DDoS attacks caused confirmed service disruptions within Slovak cyberspace, though the NBU did not quantify operational or financial impacts. In response, the NBU activated Slovakia's Computer Emergency Response Team (SK-CERT), directing affected organizations to report incidents via [email protected] for technical assistance. The agency maintained a restricted public communications posture, refusing to elaborate on mitigation measures or forensic findings beyond the initial disclosure. This operational silence persisted despite the acknowledged persistence of the threat actor group and their historical ties to Russian-aligned cyber operations. The incident marked a continuation of geopolitical cyber tensions affecting Eastern European states during this period.
