such a view 24 Channels Voiced by cybersecurity expert, founder of the HackYourMom project Mykyta Knysh. This was an attack on the core of the system, she stated.

The attack was complex

Nikita Knysh noted that hacking has two options. Attacks occur when they enter the system and retrieve some data. Such a hack is much more difficult to perform. There are also denial of service attacks.

Denial of service attacks. Think of a pipe and nothing can pass through it. Therefore, the system rejects overloaded cables and becomes unresponsive. In my opinion, it is not difficult to accuse Kyivstar of such a denial of service attack,
– explained.

A cyber security expert emphasized that SBU experts identified Russian experts behind the attack on Kyivstar.

“This is an attack on the core of the system. There are denial-of-service attacks. There are also attacks that cause denial-of-service. In my opinion, there is a more complex application behind the attack on Kyivstar,” Knysh said.

Large-scale failure at Kyivstar: the real deal

• On December 12, Kyivstar encountered a large-scale hacker attack on its network core, which caused the network to fail. As a result of the malfunction, communication services and internet access cannot be used by users. Additionally, weather warning systems and street lighting do not work in many cities.
• The company assured that customers’ personal data is safe. Kyivstar promised compensation to customers. However, General Director Oleksandr Komarov cannot yet predict the timing of the restoration of Kyivstar services.
• The Security Service of Ukraine filed a criminal case against Kyivstar, one of the national mobile phone operators, for an alleged cyber attack. They believe this may be one of Russia’s operations.
