Joerg Posted April 10, 2008 Share Posted April 10, 2008 After the recent popularity of the USB based attacks I decided it might be nice to have something from the other team, as it were, so I threw together some basic protection against them. I'll not release the source yet, it's an absolute mess, but I will release the photo for anyone who'd like to test it... It's available below and contains a warning message to explain what the mod does. It's nothing special, admittedly, and I'd really rather not get into an arms race with it but I thought it'd be something to keep me occupied and might be useful to someone, so there it is. I may or may not continue development on it depending on whether many find it useful. Anyway, it requires a usb port and to the best of my knowledge it should work on Windows XP and Vista, both x86 and x64, and even on all versions of Linux/Unix/Mac/Solaris/BSD/DOS/... Enjoy. http://img183.imageshack.us/img183/2973/1337usbtq3.png[/img] Just don't use it! It will harm your hardware! I took the original post from Moonlit and modified it. No, his application is not redundant. Quote Link to comment Share on other sites More sharing options...
moonlit Posted April 10, 2008 Share Posted April 10, 2008 My initial reaction to this thread is thus: Are you taking the piss, mush? Quote Link to comment Share on other sites More sharing options...

moonlit Posted April 10, 2008 Share Posted April 10, 2008 Sorry, I don't understand what you mean? It's English slang for "Are you trying to make a fool of me, mate?". I'm not nearly as irritated as my reply makes me seem but I did have to try to find the humour. I'm sure it was done with nothing but good taste in mind, but it could easily be taken as a hint that my application was redundant and largely useless (and while that might be the case, at least I made an effort). I doubt that's what you meant though, if I'd thought you had posted it to suggest that, I'd have just deleted this thread. Quote Link to comment Share on other sites More sharing options...
Joerg Posted April 10, 2008 Author Share Posted April 10, 2008 Thanks for explanation. It was certainly not meant to make your application seem redundant and useless. First I wanted to write an own text saying that this method will make your computer safe forever, but it seemed a good idea for me for taking your post, changing the non-common parts and release it as a hardware solution which eliminates the problem of modified usb keys.

Appreciate the clarification, no worries, thanks. Quite a useful device, though, very discrete (though as you say, unfortunately potentially destructive).

SmoothCriminal Posted April 10, 2008 Share Posted April 10, 2008 Nice idea, that would suck for those "would be hackers" that get foiled by this. I just want to see one that gets plugged in and the device starts smoking. Quote Link to comment Share on other sites More sharing options...
digip Posted April 11, 2008 Share Posted April 11, 2008 So wait, you modify a USB port so that when someone plugs in a USB key it fries their thumbdrive? I mean, wouldnt that also pose the potential to damage the PC as well? I'd much rather just disable the USB int he BIOS, password protect it, then disable all USB devices in Device Manager, or even use some sort of Group Policy to turn the hardware off. I dont need a fire breaking out just to stop someone from trying to use a USB hack on my box or laptop. If your going to mod it, why not just REMOVE any USB hardware to begin with.

Joerg Posted April 13, 2008 Author Share Posted April 13, 2008 Nope, i shorted the plug of a normal thumbdrive. That would only harm the mainboard/thumbdrive. But if i change 1 2 3 4 -> 2 1 4 3 of a normal usb cable it fries any plugged in thumbdrive. Quote Link to comment Share on other sites More sharing options...
digip Posted April 13, 2008 Share Posted April 13, 2008 Someone should design pc (and server) case that has locking covers and doors over hardware ports, so if I want to keep people from using the USB ports on my pc, I have to use somehting like a vending key to unlock the cover or case. Implement that on something like a laptop somehow and it would probably make a good selling point. Quote Link to comment Share on other sites More sharing options...

I was thinking a digital combo lock would be better. Like this: |0|1|2|3|4|5| Quote Link to comment Share on other sites More sharing options...

Like this: |0|1|2|3|4|5| That would probably be picked quicker than a vending lock, but still, a good idea because the average person walking by you in a cafe is going to move past you to teh easy targets just becase there is no viewable ports available. Even have a lock so you can keep them form opening the lid on a laptop, so if they steal it, the woudl hav eto hack it apart with something, thus defeating the purpose of stealing a laptop if you just going to end up destroying it.
