Description
On October 24, 2023, the websites of the Czech Interior Ministry and Police became inaccessible due to a cyberattack during the morning hours. Ondřej Krátoška, a spokesperson for the Interior Ministry, confirmed the incident involved a distributed denial-of-service (DDoS) attack that overwhelmed networks with excessive traffic volumes. The ministry implemented immediate protective measures upon detecting the disruption, including restricting foreign access to the affected systems. Service degradation persisted throughout Tuesday morning as technical teams worked to mitigate the attack. The Interior Ministry communicated these developments publicly via its official account on the social media platform X (formerly Twitter), though it did not specify the duration of full service restoration.

GenDigital, an antivirus software company, attributed the attack to the pro-Russian hacker collective NoName057. According to their analysis, the same group also targeted websites belonging to the Czech government, Chamber of Deputies, and Senate, indicating a broader campaign against state institutions. The coordinated nature of these disruptions suggests intentional targeting of critical government infrastructure, though the article does not specify whether data breaches or permanent damage occurred beyond temporary service unavailability. NoName057's involvement aligns with its established pattern of conducting DDoS operations against entities opposing Russian geopolitical interests. The incident caused operational disruptions to public-facing digital services of key security and legislative bodies, though the Interior Ministry's prompt access restrictions likely contained the attack's propagation. No additional technical details regarding attack vectors, traffic volumes, or secondary exploits were disclosed in the available reporting.
