Denys Gulmagomedov, deputy director of the bureau, told about this in the Ukrinform program “Samokhvalov asks.”

Answering questions specifically about cyber attacks against the ministry, Gulmagomedov said: “There were such facts. And they had some consequences. They were not critical, but this is what allows you to develop and defend better.”

According to the official, the cyber attacks targeted the bureau’s open network, which interacts with the open internet.

At the same time, the electronic document management system of the e-Case office is located in a closed network that has different levels of protection and is not affected.

“The attacks took place under conditions of aggression by the Russian Federation and are frequently detected even now,” Gulmagomedov added.

According to him, the information security system of NABU is well protected, confirmation of this is the received certificate of the State Model Comprehensive Information Protection System.

Additionally, the bureau works with companies that specialize in checking information security, including conducting attacks on information systems to identify vulnerabilities, according to the official.

“We pass such tests successfully from time to time,” said the office’s deputy director.
