Brief Description 

    

Nzlog is a Trojan that goes memory resident and captures the keystrokes entered by the user of the affected computer and logs them in a file this Trojan creates.

The file created by Nzlog could be dangerous in the hands of a hacker that managed to gain access to the affected computer, as the file could contain confidential data, such as the user name and password for accessing certain services.

It is important to highlight that it only creates this file in computers with the directory C:\ Program Files. If this directory does not exist, Nzlog doesn't do anything.

Visible Symptoms 

    

Nzlog is very difficult to recognize, as it does not show any messages or warnings that indicate it has reached the computer.
