Israel's Cyber Chief Warns of Digital Siege Threatening National Security
Brig. Gen. (res.) Yossi Karadi, head of Israel’s National Cyber Directorate, has highlighted the increasing threat of cyber warfare at the Cyber Week conference in Tel Aviv. He described a scenario termed 'digital siege,' where critical infrastructure such as power stations, traffic systems, and water supplies could be disrupted remotely. This marks a shift from traditional cyber espionage to more aggressive tactics aimed at civilian disruption. The evolution of cyber warfare was traced back to the Stuxnet worm in 2010, which targeted Iran's nuclear facilities. Recent incidents, such as the attempted alteration of chlorine levels in Israel's water system by Iranian hackers, underscore the growing threat. The use of proxy cyber gangs by states like Iran and Russia complicates attribution and response, as these groups blur the lines between criminal activity and state-sponsored attacks.
