"Russian Cyber Intrusion Persisted for Months in Ukraine Telecom"

Ukrainian telecoms giant Kyivstar was the target of a significant cyberattack by Russian hackers, believed to be the military spy unit Sandworm, who had access to the system since at least May 2023. The attack, which coincided with Ukrainian President Zelenskiy's visit to Washington, resulted in the destruction of Kyivstar's "core," affecting services for millions and potentially compromising personal data. Despite the severity, the Ukrainian military's operations were not strongly impacted, and Kyivstar's services have been fully restored. The SBU is still investigating the exact penetration method, while the attack serves as a stark warning to the West about the capabilities and intentions of Russian cyber warfare.
