Windows 7: USB flash drives masquerading as keyboards

USB flash drives masquerading as keyboards

The flash drives get around Microsoft's security mechanisms by tricking the operating system into thinking that the memory stick is not a memory stick but instead a 'Human Interface Device,' such as a keyboard.

Within 50 seconds of first plugging one of these devices into a PC, the malicious scripts or files contained on it will be run and the system is compromised. This load time is cut down substantially on subsequent mountings of the device. Without a physical inspection of the device, it's almost impossible to tell it apart from a benign flash drive.

And the price is cheap, with a modified 128MB USB stick costing $54, and a 8GB version costing only $64.
Apparently, they seem to have a found a way to bypass the protection measure by tricking Windows into thinking that the connected USB memory stick is actually a ‘Human Interface Device’ (keyboard for instance), allowing them to (physically) execute custom scripts within 30/40 seconds of connecting the custom USB memory stick to the targeted PC.

I'm surprised it took this long for someone to implement this idea.

I get the feeling that cheap USB flash drives from Asia that are sold on eBay are about to become rather risky. If someone were so inclined they could infect hundreds of PCs with a cheap BIN priced listing.
