Haha - yeah, those that are students of destructive entry (vs. non-destructive entry, or "NDE") have actually come up with some pretty badass lock-specific drill rigs.
On the Kaba Mas? I've been in love with that lock since back when it was the Mas Hamilton X-07 and I've heard that there may be/is an X-10 out now? Anyway, the lock is fantastic. It's an example of a perfect or near-perfect seal. The point of this lock is that you can't get into it without someone knowing you have. As far as destructive entry is concerned you could probably kick the thing hard enough and get it off the safe (it's mostly plastic parts) but surreptitious entry? Near impossible. A few of my favorite features:
1: Irregular # appearance. One of the simplest attacks on safes is to shoulder surf them. Even when people are aware enough to protect what they are looking at, you can typically just make a notch at, say, 4 o'clock on the dial and watch what numbers hit your new index point as someone dials in the correct combination. With the X-09 the numbers appear at odd intervals. The distance you dial to get from 1 to 2 is different than the distance dialed from 2 to 3. Also, the spacing scrambles every time you reverse direction on the dial.
2: Lockout mechanism. The X-09 has a very
aggressive lockout mechanism. Basically - even if you could automate the dialing process after a few incorrect entries you get locked out for ... some amount of time. I can't remember the specifics, bah! But anyway - real pita
3: Random black light luminescent dye sprayed inside. So - because these locks are so aggressive on their lockout cycle and because they are kind of weird to use for the average user, if you show up to work one day and can't get into your X-09, the average user will assume the damn lock is broken and will call in a technician to fix or replace it. As an attacker, you can take advantage of this by simply bashing your way through the X-09 you are attacking, and installing a new one on your way out. However! The first thing the technician will do is inspect the interior of the lock, which had a random pattern of UV dye sprayed inside of it upon its manufacture. If what he sees doesn't match up to his photographic documentation, he knows the lock isn't broken, it's been replaced.
