Oct 06, 2009  Long, long ago we covered a method to crack a Master lock in about 30 minutes or less. Here’s a revival of the same method but now the instructions to retrieve the combination are in info. Resettable combination locks have a combination that is assigned by the owner of the lock. Therefore, Master Lock does not have record of the combination that the owner set. The lock cannot be reset unless it is in the open position. If your lock is attached to something, you will need to call a. Autocad isolate layer turn off.

Forgot your Master lock combo? Or want some incentive to not use a Master padlock? There’s a website for that.

The video above from Samy Kamar shows how you can crack any Master combination lock within eight tries. It’s a bit long, but here’s Ars Technica’s explanation if you don’t want to sit through the video:

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. Before the dial reaches 11, there will be three points where the dial will resist being turned anymore. One of them will be ignored as it is exactly between two whole numbers on the dial. The remaining two locations represent locked positions. Next, an attacker again lifts the locked shackle, this time with less force, while turning the dial clockwise. At some point before a full revolution is completed, the dial will resist being turned. (An attacker can still turn through it but will physically feel the resistance.) This location represents the resistance location. The two locked positions and the one resistance position are then recorded on a Web page that streamlines the exploit.

Cracking a combination lock is much different than the picking method above. The one we just outlined is very physical in nature, but this one we are about to show you is very cerebral. So, at the basis of this method is math.
2. Crack any Master Combination Lock in 8 Combos or Less. Master Combo Locks have been known to be vulnerable to an attack reducing their 64,000 possible combinations down to 100. I've devised a new attack reducing the amount of work down to only 8 combinations to crack any Master combo lock, and have simplified the process.

The page responds with the first digit of the combination and two possible digits for the last digit. By testing which of the possible last digits has more “give,” an attacker can quickly figure out which one is correct. By eliminating the false digit from the Web form, the page will automatically populate the eight possible numbers for the second digit of the combination. Now that the attacker knows the first and last digits and knows the second digit is one of eight possible numbers, the hack is a simple matter of trying each possible combination until the correct one opens the lock.
