It can track users’ online activities, steal personal information and credentials, and change browser and DNS settings. Tofsee has been known to spread through malicious email attachments, infected software downloads, and drive-by downloads from compromised websites. It can also persist on a system even after a reboot and can hide its presence from antivirus software. Upon execution, it drops multiple files onto the system and modifies the registry to ensure persistence.

This malware can cause major damage, such as financial loss and computer infections. It is used by cybercriminals to generate as much revenue as possible. The program is likely to install unintentionally, causing a slew of issues for both the system and other users.
