Summary
A remote administration tool (RAT) that bypasses the security features of a program, computer or network to give unauthorized access or control to its user.
Removal
Based on the settings of your F-Secure security product, it will either move the file to the quarantine where it cannot spread or cause harm, or remove it.
A False Positive is when a file is incorrectly detected as harmful, usually because its code or behavior resembles known harmful programs. A False Positive will usually be fixed in a subsequent database update without any action needed on your part. If you wish, you may also:
Check for the latest database updates
First, check if your F-Secure security program is using the latest updates, then try scanning the file again.
Submit a sample
After checking, if you still believe the file is incorrectly detected, you can submit a sample of it for re-analysis.
Note: If the file was moved to quarantine, you need to collect the file from quarantine before you can submit it.
Exclude a file from further scanning
If you are certain that the file is safe and want to continue using it, you can exclude it from further scanning by the F-Secure security product.
Note: You need administrative rights to change the settings.
Technical Details
Backdoor:W32/SdBot.CKN is a backdoor trojan that attempts to contact a remote server and allow a remote attacker access to the infected machine.
Installation
After the backdoor's file is run, it checks for the existence of Virtual Machines (VM) and immediately exits if any VM environment such as VMware is detected.
If no VM environment is present, the backdoor decrypts its code and injects it into the explorer.exe process.
Activity
Once active, the backdoor attempts to connect to the following remote IRC server on TCP port 81:
- [Removed].xn--mg-kka.com
The backdoor generates a random nickname and joins a password-protected channel:
- #ohai
The backdoor then waits for commands from a channel operator.
A remote hacker who is controlling the backdoor can do any of the following:
- Update the backdoor's file from the Internet
- Perform an SYN flood
- Perform a Distributed Denial of Service (DDoS) attack
