ServU.FS is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions.
It reduces the security level of the computer:
it awaits remote-control orders received through
IRC or FTP; it changes system permissions, decreasing the security level.
It uses several methods in order to avoid detection by antivirus companies:
- It terminates its own execution if it detects that it is being executed in a virtual machine environment, such as VMWare or VirtualPC.
- It terminates its own execution if it detects that a debugging program is active.
ServU.FS uses the following propagation or distribution methods:
- Exploiting vulnerabilities with the intervention of the user: exploiting vulnerabilities in file formats or applications. To exploit them successfully it needs the intervention of the user: opening files, viewing malicious web pages, reading emails, etc.
- Via Internet, exploiting remote vulnerabilities: attacking random IP addresses, in which it tries to insert a copy of itself by exploiting one or more vulnerabilities.
