While 3D printers have been widely adopted as hacking machines, with the express purpose of customizing and improving existing objects, one Redditor reminds us that they can obviously also be used for the Hollywood definition of hacking. Readers will doubtlessly remember Chinese maker and redditor SexyCyborg, who recently skyrocketed to internet fame for designing and 3D printing the quite sexy underlit skirt. As you can see below, she recently also scanned and 3D printed herself in her trademark sexy outfit. Well, she is now back for more and has 3D printed a set of hollow high heels, with the express purpose of secretly carrying a penetration testing kit around.

As SexyCyborg explained, this latest cool project was inspired by the TV show ‘Mr. Robot’ ‘I know not all of it is accurate, though some of it is and it got me curious. I’m already pretty comfortable with command line and remote server administration from my web development work, and it turns out a lot of ‘hacking’ tools are just testing tools any sensible IT professional would use- just without a GUI,’ she says. So she began reading up on penetration testing, and began looking for ways to bring it into practice.

Of course, assembling a kit itself isn’t so difficult, but actually using it outside your own home is. ‘So I got to thinking- if I had to do penetration testing on a corporate facility, how would I do it? A handbag would be suspicious and leaving cell phones at the gate would be standard practice in any reasonably secure facility,’ she says, adding that her typical outfits don’t feature a lot of pockets. That’s why she developed these Wu Ying Shoes – Penetration Testing Platform Heels. ‘[The name] means “shadowless", the name is from the folk hero Wong Fei Hung’s (黄飞鸿) famous "shadowless kick" (无影脚). Wong Fei Hung is from Foshan, which is my ancestral home as well as the ancestral home of Bruce Lee,’ she explains. This kick would require a distraction from the upper body before striking, and that is exactly the purpose of these shoes. ‘With my shadowless shoes I distract the target with my…upper body and they don’t see the real danger on my feet,’ SexyCyborg explains.

These Wu Ying Shoes are fully 3D Printed, and have been fully designed in SexyCyborg’s software of choice – TinkerCAD. ‘I had to print it at 0.3mm so the layers are a little coarse. It was taking forever at 0.2 mm,’ she adds. Printing was done in PLA with 20% infill, and obviously quite a lot of support material. The Chinese maker adds that the shoes are fully capable of supporting her weight without being very heavy themselves. Unfortunately, she failed to mention if they’re comfortable – though we doubt it. Still, you can find out for yourself by downloading the 3D printable files from Thingiverse here.

So how do these high heels work? Well, each shoe features a drawer that can be removed without even taking off your shoes. Each drawer can further be customized to suit various payloads. ‘For the purposes of this first test version, my right shoe contains a pen testing drop box. This is a wireless router running OpenWRT with a built in rechargeable battery that could either be left running inside the shoe (for war-walking, wifi sniffing and logging etc) or could be removed and plugged into a convenient open network jack as soon as I was inside and had direct access to the LAN. Once this is done you can gain remote access anytime you want via SSH tunnel,’ SexyCyborg explains.

OpenWRT, she adds, runs very well on the TL-MR10U and functions just like upgrading firmware on a router. ‘It’s two links and a button- nothing to it. There’s a lot of different software you can run once you have OpenWRT flashed. This router may-or-may-not be running a custom version of Wispi for the TP-Link TL-MR10U because if it was it would probably be illegal in China so maybe its not,’ she adds. Hacking itself could take place through Jasager/Karma or others. ‘Wispi also has a few other handy utilities that you should never use in the real world but are pretty cool to try at home once or twice just so you know how,’ she advises.

The left shoe, meanwhile, carries the rest of the necessary equipment, including a USB keystroke recorder to extract everything typed into a keyboard easily, as well as a retractable Ethernet cable for the router, a shim and a basic lockpick set. The latter two are obviously useful for opening doors, filing cabinets and more. If you’re planning on breaking into corporations, you might as well do it properly.

As cool as this set is (and as detailed as her knowledge is), SexyCyborg is quick to assure all of us that she isn’t planning to do anything criminal – it’s just good to have the knowledge available should you need it. ‘People think all sorts of crazy stuff about China and I don’t want to talk politics- but my city Shenzhen is a really, really cool place to live so there’s really no reason to do dumb stuff,’ she concludes. And that’s very fortunate, as the internet wants to see a lot more of her projects in the near future.
