No, you cannot hide an executable inside a picture using steganography. Steganography can only be used to hide text, and encrypted it.

If you want to hide an executable, use a "wrapper" instead.

backtrack 3 doesn't automatically turn your network interface on. you have to turn it on by yourself. do these from console:
1. ifconfig /all (to see all your network interface)
2. ifconfig eth1 up (to bring eth1 up and running, assuming eth1 is your wifi interface)

Hi there!

I find the same error when trying to run backtrack with an old monitor. I believe the vertical sync frequency of the monitor is out of backtrack's frequency range (backtrack 3 uses 85 Hz @ 1024x768 resolution). And I cannot set the frequency to a lower one, say 65 Hz, from within backtrack O/S.

The good news is I don't find the same problem when running backtrack with newer monitors, or when running backtrack via VMWare. So may be you should try it with vmware first.
