You've heard about wardriving, but what about warshipping? Researchers at IBM X-Force Red have detailed a new tactic that they say can break into victims' Wi-Fi networks from far.

The company calls the technique warshipping, and it is a more efficient evolution of wardriving, a popular technique among hackers seeking access to any wireless network they can find. Whereas wardrivers drive around a wide area with a directional antenna looking for wireless networks to crack, IBM's researchers took a more targeted approach.

Speaking at Black Hat USA, IBM researchers explained how they used off-the-shelf components costing under $100 to create a single-board computer with Wi-Fi and 3G capability. This enables it to connect to a Wi-Fi network to harvest data locally and then send it to a remote location using its cellular connection. The small device runs on a cell phone battery and easily fits into a small package.

Attackers can then send the device to a company via regular mail, where it will probably languish in a mail room for a while. During this time, it can connect to any Wi-Fi networks it finds in the building and harvest data – typically a hashed network access code. It sends this back to the attacker, who can then use their own resources (or a cloud-based cracking service) to extract the original access code. At this point, they have access to the company's Wi-Fi network.

Black Hat IBM's X-Force hacking team have come up with an interesting variation on wardriving – you know, when you cruise a neighborhood scouting for Wi-Fi networks. Well, why not try using the postal service instead, and called it "warshipping," Big Blue's eggheads suggested earlier today.

To demonstrate this approach, the X-Force team built a low-power gizmo consisting of a $100 single-board computer with built-in 3G and Wi-Fi connectivity and GPS. It's smaller than the palm of your hand, and can be hidden in a package sent out for delivery to a target's business or home.

Once it arrives, it can be activated remotely over the internet, or when it detects it is near its destination using GPS. It can be instructed to scan for vulnerable networks to infiltrate – a la the TJX wireless hacking in the mid-2000s – or spoof nearby legit wireless networks to harvest passphrases from those connecting, or get up to other mischief over the air.

Any obtained information can be relayed back to base, over the internet, and it can be commanded to drill further into any networks it is able to break into, installing spyware as it goes. This widget is potentially potent as it passes through a business on its way to someone's desk.
