| HTTPS | 443 | Updating databases and application modules. Checking if Kaspersky servers are accessible. If access to the servers using system DNS is not possible, the application uses public DNS. This is necessary to make sure anti-virus databases are updated and the level of security is maintained for the computer. Kaspersky Anti-Ransomware Tool uses the following list of public DNS servers in the following order:
Requests emitted by the application may contain addresses of domains and the public IP address of the user because the application establishes a TCP/UDP connection with the DNS server. This information is needed, for example, to validate the certificate of a web resource when using HTTPS. If Kaspersky Anti-Ransomware Tool is using a public DNS server, data processing is governed by the privacy policy of the relevant service. |
