As of 11.30 am on Monday, the website of the company-developer of public websites affected by the hacker attack, Kitsoft, has not been put into operation.

The company itself on its Facebook page on Saturday night published an update of the post about the hacker attack.

According to Kitsoft, this hacker attack was of a complex nature and several vectors for the development of scenarios, and its goal is to destabilize and stress the situation in the country.

"We test public websites that are supported by our company for vulnerabilities in due time, fix errors and update them. Unfortunately, not all customers enter into contracts for website support, and, accordingly, we do not have access to them and the ability to update them, because all rights after development are transferred to the customer. To prevent such attacks, it is important for the state to allocate resources for regular support and updating of IT systems," Kitsoft said.

The company also said that they continue work to restore the affected information resources.
