CmdShell 2.0
(Backdoor.Win32.VB.dkx for EditServer)
(Trojan.Win32.Genome.aqae for Server)

by BlackCobra

Released in May 2007

Written in Visual Basic


This application is based on the fwb injection technique
completely coded in vb. No c/c++/Delphi dlls or other is used
for injection. Purely in vb.

As the name suggests open a port on the victim computer and
you can telnet to the target port and you will have the cmd shell.

The application is not using any of the vb form.


EditServer
