A hacker at HOPE presented a pair of 3D printed "high security" handcuff keys that unlocked cuffs whose designs are supposed to be secret and not widely available. They will shortly be on Thingiverse for you to download. Forbes's Andy Greenberg reports:
In a workshop Friday at the Hackers On Planet Earth conference in New York, a German hacker and security consultant who goes by the name “Ray” demonstrated a looming problem for handcuff makers hoping to restrict the distribution of the keys that open their cuffs: With plastic copies he cheaply produced with a laser-cutter and a 3D printer, he was able to open handcuffs built by the German firm Bonowi and the English manufacturer Chubb, both of which attempt to control the distribution of their keys to keep them exclusively in the hands of authorized buyers such as law enforcement.
The demonstration highlights a unique problem for handcuff makers, who design their cuffs to be opened by standard keys possessed by every police officer in a department, so that a suspect can be locked up by one officer and released by another, says Ray. Unlike other locks with unique keys, any copy of a standard key will open a certain manufacturer’s cuff. “Police need to know that every new handcuff they buy has a key that can be reproduced,” he says. “Until every handcuff has a different key, they can be copied.”
Unlike keys for more common handcuffs, which can be purchased (even in forms specifically designed to be concealable) from practically any survivalist or police surplus store, Bonowi’s and Chubb’s keys can’t be acquired from commercial vendors. Ray says he bought a Chubb key from eBay, where he says they intermittently appear, and obtained the rarer Bonowi key through a source he declined to name. Then he precisely measured them with calipers and created CAD models, which he used to reproduce the keys en masse, both in plexiglass with a friend’s standard laser cutter and in ABS plastic with a Repman 3D printer. Both types of tools can be found in hacker spaces around the U.S. and, in the case of 3D printers, thousands of consumers’ homes.
