Norwegian Immigration Website Hit by Pro-Russian DDoS Attack On September 4th, the Norwegian Directorate of Immigration (UDI) suffered a cyberattack, taking its official website offline. The attack a Distributed Denial of Service (DDoS) assault was claimed by the pro-Russian hacker group "Server Killers." A DDoS attack overwhelms a target with excessive traffic, rendering it inaccessible. The same group had previously targeted several Norwegian universities and colleges earlier in the week, raising concerns about escalating cyber threats against public sector services. Users attempting to access UDI’s portal encountered error messages, disrupting immigration-related services, including information requests and paperwork submissions. As of the attack, UDI had not provided a timeline for restoring normal operations. The incident underscores growing vulnerabilities in government digital infrastructure amid heightened geopolitical tensions.
