According to Vedomosti, the record scale of the cyberattack was confirmed by the American company Cloudflare, which specializes in repelling such attacks and cooperates with Yandex. Details in "Yandex" did not disclose, explaining this internally by checking and clarifying that the investigation is being carried out together with the contractors.
“We are talking about a threat to the infrastructure on a national scale”, - the source said, but did not answer whether the company had filed a complaint with the FSB or the police.
At the same time, it is indicated that the incident did not affect the operation of the services, and user data did not suffer.
Let's remind that the last large-scale failure at Yandex happened at the end of last month. At that time, more than 440 complaints were filed for the work of applications.
