Pro-Russian threat group Killnet has attacked several Czech entities in recent days. Killnet is targeting those it sees as adversaries of Russia in the Russia-Ukraine war. The Czech National Cyber and Information Security Agency – NKIB or NCISA – says some Czech websites have been under severe DDoS attacks by hackers since the beginning of the week. These include Czech railways, the Karlovy Vary and Pardubice airports, and the public administration portal, which was not operational for several days. Interior Minister Vt Rakuan says no information or private citizen data was stolen in the attacks.”]
