Agent.CKH is a Trojan, which although seemingly inoffensive, can actually carry out attacks and intrusions. 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 uses stealth techniques to avoid being detected by the user: - 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.
- It terminates its own execution if it detects that a debugging program is active.
Agent.CKH does not spread automatically using its own means. It needs an attacking user's intervention in order to reach the affected computer. The means of transmission used include, among others, floppy disks, CD-ROMs, email messages with attached files, Internet downloads, FTP, IRC channels, peer-to-peer (P2P) file sharing networks, etc. |
