The #tsa is learning a basic lesson of physical security in the age of 3-D printing: If you have sensitive keys—say, a set of #master keys that can open locks you’ve asked millions of Americans to use—don’t post pictures of them on the Internet.
A group of lock-picking and security enthusiasts drove that lesson home Wednesday by publishing a set of #cad files to Github that anyone can use to 3-D print a precisely measured set of the TSA’s master keys for its “approved” locks—the ones the agency can open with its own keys during airport inspections. Within hours, at least one 3-D printer owner had already downloaded the files, printed one of the master keys, and published a #video proving that it opened his TSA-approved luggage lock.
