Russian Hackers Target 

Russian hackers infiltrated the system of Kyivstar, Ukraine’s telecom giant, in a cyberattack in December, according to the head of cybersecurity for Ukraine Illia Vitiuk.

He revealed that the attack, attributed to the Russian military intelligence cyberwarfare unit Sandworm, had significant consequences as it caused disruptions to Kyivstar’s services, resulting in over 24.3 million customers losing phone reception. The attack’s implications went beyond the telecoms company, with disruptions also reported by banks and Ukrainians in the country’s eastern war zone left without a connection.
