Brief Description | |
Gaobot.QJS is a worm that spreads by copying itself, without infecting other files. It affects productivity, preventing tasks from being carried out: - In the affected computer:
it converts the computer into a platform for taking malicious action surreptitiously: spam sending, launch of Denial of Service attacks, malware distribution, etc.
It reduces the security level of the computer:
it awaits remote-control orders received through
IRC. It uses stealth techniques to avoid being detected by the user: - It injects itself in running processes.
- It deletes the original file from which it was run once it is installed on the computer.
Gaobot.QJS 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.
- IRC: It sends a copy of itself to all users connected to the channel to which the infected user is connected.
- 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.
