Hacker 3D prints device that can crack a combo lock in 30 seconds

Brings back the memories

The device really is clever, but the same two problems that it exploits have been around forever in Masterlocks. First is that the combination is never truly random, and second is that the shackle-and-dial variability of resistance leaks a great deal of information which can be used to drastically reduce the number of possible combinations, allowing brute forcing. I got pretty good at this back in the university days, where I could open most Masterlocks in fifteen or or twenty minutes. Inexpensive multi-dial locks are a lot easier, key locks (with picks) can be easier or harder (thank you MIT guide).

I would hope no one is actually using a consumer grade Masterlock to protect anything extremely valuable or dangerous anyway, but I'm sure some government paper-pusher who had one in high school just ordered a gross for securing nuclear weapons or something.
