Kamkar told Ars his Master Lock exploit started with a well-known vulnerability that allows Master Lock combinations to be cracked in 100 or fewer tries. In 2005, he unleashed the Samy worm, a cross-site scripting exploit that knocked MySpace out of commission when it added more than one million MySpace friends to Kamkar's account. The technique was devised by Samy Kamkar, a serial hacker who has created everything from stealthy keystroke-pilfering USB chargers to DIY stalker apps that mined Google Streetview. The two locked positions and the one resistance position are then recorded on a Web page that streamlines the exploit.īreak open any Master Combo Lock in 8 tries or less!
(An attacker can still turn through it but will physically feel the resistance.) This location represents the resistance location. At some point before a full revolution is completed, the dial will resist being turned. Next, an attacker again lifts the locked shackle, this time with less force, while turning the dial clockwise. The remaining two locations represent locked positions. One of them will be ignored as it is exactly between two whole numbers on the dial.
Before the dial reaches 11, there will be three points where the dial will resist being turned anymore. The exploit involves lifting up a locked shackle with one hand while turning the combination dial counterclockwise starting at the number 0 with the other.
There's a vulnerability in Master Lock branded padlocks that allows anyone to learn the combination in eight or fewer tries, a process that requires less than two minutes and a minimal amount of skill to carry out.
