Brief Description | |
IRCBot.CSO 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
HTTP or FTP. 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 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.CSO 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 (shared resources): it creates copies of itself in shared network resources to which it has access.
