Maybe “IDE Sniffing” is a bit misleading…but I was not sure how to call it otherwise. So this is the problem context: You need to know if a harddisk is encrypted but you are not allowed to disconnect or move the computer. You have no access to the computer, like no login,no firewire to exploit and no vulnerable services running. Let’s also assume that this computer is using normal IDE ( I know it’s a bit outdated) disks. How on earth are we going to find out?

Investigators have got some nifty devices which are capable of moving your pc without disconnecting it. Effectively bypassing FDE/WDE encryption if you are not used to lock your computer. Although locking doesn’t seem to be the answer nowadays with all those firewire hacks. So what’s left to do?

First of all disable firewire and make sure you always lock your pc. In the strange case that you do not lock your pc I made some easy yet (this hasn’t been tested in a real life situation) effective code to frustrate the investigator. This is just some quick POC (forgive me the messy code) I wrote. In a lab environment this works, so don’t blaim me if this doesn’t work in a real life situation.
