Researchers at DefCon in Vegas have demonstrated that they can make "high security" Medeco key-blanks out of the plastic used in credit-cards, and then whittle them into working keys by referring to low-resolution photos of original keys.
"Basically, we've destroyed Medeco's key control, because we can make (plastic keys) for any of their M3 locks and a lot of their Biaxial locks, which is their last generation of locks," says Tobias, who authored the book Open in Thirty Seconds, with Bluzmanis.
The researchers demonstrated the technique using a Medeco mortise cylinder that Threat Level purchased in California before leaving for Las Vegas. After buying the lock, Threat Level scanned the key and e-mailed the image to the researchers, who then created several plastic keys. When Threat Level arrived in Las Vegas with the lock, it took about six seconds to open the lock using a plastic key.
"It's keys by e-mail," says Tobias. "It's key-mail."...
The Medeco M3 key does have an extra feature to secure the lock -- a step protrusion on the side of the key that's designed to move a slider inside the lock. But last year at DefCon, Tobias and his colleagues showed how they could simply insert the end of a bent paper clip into a Medeco high-security lock to push back the slider, rendering the slider ineffective as a security layer. Once that is done, they're then able to insert the plastic key in this new attack, to lift and rotate the pins.

CutiePi is a tablet based on the Raspberry Pi: compact enough, but more open, versatile and hacker-friendly than mainstream models from Apple, Microsoft or the Google coprosperity sphere. CutiePi is a complete Raspberry Pi in a tablet form factor, minus the trouble of connecting monitor or power supply. It’s slimmer because of using Compute Module, […]
I am addicted to Thinkpads in large part because of the trackpoint (AKA "The Nipple") -- the little wiggly joystickbetween the G, H and B keys that allows me to control fine mouse-movements without bending my hand into the RSI-inducing trackpad position; between that and the amazing, best-in-class warranties, I am a committed Thinkpad user, […]
You can buy microcontrollers for as little as 3 cents, if you order a lot of them, a staggeringly cheap number even if you’re so young you don’t know a Zilog Z80 was $10 in 1978 money. But are these cheapo parts any good? Hackaday says they’re terrible, but Tim finds a role. [it] surely […]
If your office works at all, it uses Microsoft Office. Those icons for Word, PowerPoint, and Outlook are as familiar around some workplaces as the coffee machine. So familiar, in fact, that they get taken for granted – and rarely used to their full potential. Whether you need a crash course in the essential tools […]
It’s a great time to be a maker. 3D printers are on store shelves for anyone to buy, and coder kits like Arduino and Raspberry Pi are letting kids as young as 9 or 10 dive into the Internet of Things. Here are a few examples of our favorite tech toys, all priced low enough […]
