The company’s press service informed Ukrinform about this.

Kyivstar noted that voice communication is already available to subscribers and the “Internet at Home” service is also available. Restoration of mobile data transmission services has begun.

Ivano-Frankivsk was the first region where Kyivstar restored mobile internet.

“Stabilization of the network and restoration of other services are being carried out gradually to avoid overloading the network. In some settlements there are still short-term difficulties with the quality of communications, but our experts are eliminating them,” he said.

They reminded me that you need to reboot the phone or toggle the “airline” mode on and off when the SIM card is not registered on the network.

As Ukrinform reported, on the morning of December 12, the operator “Kyivstar” became the target of a powerful hacker attack, which led to a technical malfunction. Communication and internet access services became unusable.

The company assured that subscribers’ personal data will not be compromised. They also promised compensation to subscribers who did not have a connection or could not use the operator’s services.

The Security Service of Ukraine has initiated criminal proceedings regarding the cyber attack on Kyivstar. One of the versions of the investigation involved the participation of Russian special services.

It was learned that Solntsepek, one of the so-called hacker groups of the Russian Federation, claimed responsibility for the attack on Kievstar on December 13.
