"Russian Cyber Offensive Disrupts Ukrainian Telecom, Signaling Escalation in Cyber Warfare"

Russian hackers, believed to be part of the Sandworm group, launched a cyberattack on Kyivstar, Ukraine's largest telecom service provider, wiping thousands of systems and causing significant service disruptions for millions of subscribers. The attack, which was prepared for months, did not affect military communications due to different protocols used by Ukraine's Defense Forces. The Security Service of Ukraine (SSU) has been investigating the incident and confirmed the involvement of the Sandworm group, which has also targeted other Ukrainian telecom operators.
