When a ransomware threat like Killnet infiltrates a system, it immediately executes the file encryption process. Most of the times users don’t even notice until all their data gets locked. During this process, all the important files – documents, media, databases, backups, archives, etc. get encoded. After successful encryption, a ransom note is created to inform victims about the attack.

The main purpose of the ransom note is to demand money from users in return for the decryption of their data. It also contains information about how to contact the attacks and other warnings. Killnet virus can also delete shadow files and restore points to prevent users from restoring their data. It can also disable your anti-virus and firewall security to make your system defenseless.
