If the connection to its command server has not been established, then the ransomware uses a fixed key (so-called ‘offline key’). If this succeeds, the ransomware sends data about the infected computer to the server, and from it receives a key (so-called ‘online key’) necessary for file encryption. After that, Tuow virus tries to connect to its command server. Upon execution, the ransomware creates a directory in the Windows system directory, copies itself to this directory, changes some OS settings, and also collects information about the infected computer. Typically, ransomware like Tuow can infect a computer when a user runs and installs the infected program as well as cracked games, freeware, Microsoft Windows/Office key generators and other similar software. Tuow virus sneaks into the system without any visible symptoms, which is why users notice that their computer is infected too late, when the files are already encrypted. It is designed to encrypt files located on the victim’s computer, and then extort money to decrypt them. Tuow ransomware is a variant of the STOP (Djvu) ransomware. ![]() ![]() ![]() Screenshot of files encrypted by Tuow virus (‘.tuow’ file extension) QUICK LINKS
