Russian hackers were inside Ukrainian telecoms giant Kyivstar’s system from at least May last year in a cyberattack that should serve as a “big warning” to the West, Ukraine’s cyber spy chief told Reuters.
The hack, one of the most dramatic since Russia’s full-scale invasion nearly two years ago, knocked out services provided by Ukraine’s biggest telecoms operator for some 24 million users for days from Dec. 12.In an interview, Illia Vitiuk, head of the Security Service of Ukraine’s (SBU) cybersecurity department, disclosed exclusive details about the hack, which he said caused “disastrous” destruction and aimed to land a psychological blow and gather intelligence.”This attack is a big message, a big warning, not only to Ukraine, but for the whole Western world to understand that no one is actually untouchable,” he said. He noted Kyivstar was a wealthy, private company that invested a lot in cybersecurity.The attack wiped “almost everything”, including thousands of virtual servers and PCs, he said, describing it as probably the first example of a destructive cyberattack that “completely destroyed the core of a telecoms operator.”
During its investigation, the SBU found the hackers probably attempted to penetrate Kyivstar in March or earlier, he said in a Zoom interview on Dec. 27.
“For now, we can say securely, that they were in the system at least since May 2023,” he said. “I cannot say right now, since what time they had … full access: probably at least since November.”
