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.
