USB - Unfixable Security Broken

It is well known that USB drives can be dangerous. Companies run strict screening policies and it has long been known that running unknown ‘exe’ files is a bad idea. But what if the threat was undetectable, unfixable and could be planted into any USB device be it a USB drive, keyboard, mouse, web camera, printer, even smartphone or tablet? Well this nightmare scenario just became reality.

The findings will be laid out in a presentation next week from security researchers Karsten Nohl and Jakob Lell who claim the security of USB devices is fundamentally broken. More to the point they said it has always been fundamentally broken, but the holes have only just been discovered.

BadUSB

To demonstrate this the researchers created malware called ‘BadUSB’. It can be installed on any USB device and take complete control over any PC to which it connects. This includes downloading and uploading files, tracking web history, adding infected software into installations and even controlling the keyboard so it can type commands.

“It can do whatever you can do with a keyboard, which is basically everything a computer does,” explains Nohl... (more)

The short-term solution to BadUSB isn’t a technical patch so much as a fundamental change in how we use USB gadgets. To avoid the attack, all you have to do is not connect your USB device to computers you don’t own or don’t have good reason to trust—and don’t plug untrusted USB devices into your own computer. ...or, treat USB sticks the same way you would hypodermic needles.
