During the cyber attack, the attackers managed to penetrate the operator's security system, namely the account of one of the company's employees.
Hackers hacked Kyivstar employee's account
During yesterday's large-scale cyber attack on Kyivstar mobile operator, hackers managed to breach the defences using the account of one of the company's employees.
This was stated by the president of Kyivstar, Oleksandr Komarov, on the air of the nationwide telethon Yedyni Novyny (United News).
The entrepreneur noted that this was the reason why the attackers managed to hack the operator's security system.
This happened because the account pool was compromised, the account of one of the employees was compromised, and the enemy was able to penetrate the company's infrastructure, he explained.
The company's management also clarifies that this is still being investigated by law enforcement agencies.
Kyivstar management on the status of the operator's recovery
Kyivstar's chief operating officer Mykhailo Nestor posted on his Facebook page at 18:20 that mobile communications had been partially restored.
Kyivstar specialists and our partners did everything possible to restore the network from the consequences of the unprecedented cyber attack.
As of 18:00 on 13 December 2023, our specialists have started to restore voice communications throughout Ukraine. The restoration of services will be gradual, so you may experience short-term difficulties until the end of the day. In this case, we recommend that subscribers restart their phones and disable the VoLTE service — this can be done in the phone settings.
Currently, the company's specialists are working to restore data and SMS services and hope that they will also be restored within a day.
Once the network is fully restored and stabilised, Kyivstar will start preparing and paying compensation to all subscribers and corporate clients who were unable to use the company's services as a result of the hacker attack.
