Prominent Ukrainian Telecom Provider Suffers Large-Scale Cyberattack

Ukrtelecom, a prominent Ukrainian telecommunication provider, suffered a large-scale cyberattack on March 28, but services have begun to recover, according to Ukrainian authorities.

“Today, the enemy launched a powerful cyberattack against Ukrtelecom’s [Information Technology]-infrastructure,” Ukraine’s State Service of Special Communications and Information Protection (SSSCIP) said on Twitter.

The attack has been “neutralized” and “resuming services is underway,” SSSCIP added.

SSSCIP said Ukrtelecom has temporarily limited providing its services to most of its private users and business-clients to prioritize maintaining communications services for the Ukrainian military.

Global internet monitor Netblocks described the cyberattack as “the most severe registered since the invasion by Russia.”

Netblocks earlier reported “a major internet disruption” across Ukraine on Ukrtelecom, with data showing that connectivity collapsed to 13% of pre-war levels.
