|IRCBot.CQZ is a virus that also has the characteristics of a worm. |
IRCBot.CQZ gets into a computer via e-mail, the Internet, floppy disks, etc, and it spreads by inserting its code in other files and programs. Its effects can range from simply annoying to destructive.
Furthermore, due to its worm characteristics, IRCBot.CQZ also spreads by sending out copies of itself. Its main objective is to collapse computers and networks, preventing users from working with the affected computer.
It uses stealth techniques to avoid being detected by the user:
- It uses techniques included in its code to hide itself while it is active.
- It deletes the original file from which it was run once it is installed on the computer.
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.
IRCBot.CQZ 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.
- Computer networks (mapped drives): it creates copies of itself in mapped drives.
- Computer networks (shared resources): it creates copies of itself in shared network resources to which it has access.
