A hacking group allegedly connected to Russian military intelligence carried out a cyberattack on Ukraine’s biggest mobile network operator offline, officials in Kyiv’s cyber defence agency said.
Ukraine’s Kyivstar, which provides cellular and internet services to 24.3 million mobile subscribers and over 1.1 million home internet users, came under a deadly cyberattack on Tuesday. It silenced air raid alerts in some parts of Ukraine at a time Russia started firing ballistic missiles on civilian regions, wiped out services, and damaged IT infrastructure.
