Repacks often modify the hosts file to block Kaspersky’s genuine activation servers. However, they also add a "backdoor" entry—an IP address that constantly phones home to a command-and-control server. This allows the hacker to push updates to their malware onto your machine at any time.

Once those defenses are down, the installer drops its real payload: . These allow the hacker to control your PC, turn on your webcam, and steal your files.
Status Update: Kaspersky Total Security vs. The New Subscription Lineup
