Ukrtelecom

Ukraine’s biggest telecommunications company Ukrtelecom was hit by the Russian invasion in a powerful cyber attack recently.

The attackers hit the mobile provider with a distributed denial of service (DDoS) attack and disrupted its services across the country.

There was a loss of connectivity across Ukraine due to problems with internal systems which impacted the connectivity at nation scale.
