Ukrtelecom, a prominent Ukrainian internet and phone line provider, was the target of a “powerful cyberattack” on Monday, Ukrainian officials said.
The cyberattack was “neutralized” and, as recovery from the hack continues, priority has been given to maintaining communications services for Ukraine’s military, according to a tweet from Ukraine’s State Service of Special Communications and Information Protection.
The agency blamed “the enemy,” for the hack in an apparent reference to Russia.
Connectivity at Ukrtelecom, which describes itself as the “largest fixed line operator in Ukraine,” plummeted on Monday to 13% of pre-war levels, according to NetBlocks, which tracks internet connectivity.
Ukrainian telecom providers have experienced a wave of hacks as the Russian bombardment of the country continues.
Hackers earlier this month caused outages at a Ukrainian internet service provider Triolan, which has customers in major cities.
