The Ukrainian government has confirmed neutralizing a “massive cyberattack” targeting the Ukrainian Internet Service Provider Ukrtelecom.

The State Service of Special Communications and Information Protection (SSSCIP) of Ukraine explained that Ukrtelecom was resuming services.

The agency however stated on Twitter that Ukrtelecom services will be temporarily limited.
