    That's pretty creative

    First, I just want to say that you are totally on top of most things to do with Infosec. But I have to ask you, what MAC address have you been living under? Most crack heads I know, know about freezing locks.

    You could also do it with n2o, preferably in a liquid form. In addition to freezing the lock you can also catch a quick buzz, get dental work done, and/or make whip cream.

      First off, that's a pretty shiatty lock he's using, and I wager it would fail if you hit it with the hammer anyways without the freezing agent.

      A decent lock should stand up to such beatings no mater how cold. Considering the outdoor temperature around here can get down to -40 F and C and locks continue to hold nicely all through the winter.

        I think the idea is more to freeze the locks internal parts rather than hard metal clad shell. No expert but it theory in makes sense. Metals containing a high sulfur content can become very brittle when subjected to extremely cold temperature, also many modern alloys.

        Don't know whether I read this or heard it some where but the Titanic supposedly is one such example of a metal hull containing a high sulfur content that became brittle under extreme cold circumstances. Supposedly contributed to her sinking.

        Where's a good Navy man when you need them.

          I'm not in the Navy, but I remember studying about this at UCLA (one of my engineering classes).

          The hull steel had high amounts of oxygen and sulfur. This made the steel extremely brittle under normal conditions, not just in the cold. If I remember correctly, the sulfur screws with the "grain" or molecular alignment of the steel.

          I believe a forensic team took a piece of Titanic steel and smacked it with a hammer from a known height. The piece broke cleanly. Correctly smelted steel would have a jagged edge (diagonal break instead of straight through) because it is more pliable.

          Unfortunately, that's about the only thing I remember from that class.

            I don't think most locks would stand up to Liquid Nitrogen freezing, but then that's not something that most people have access to.

            I had worked for a Defense Contractor a few years ago and we had a supply to cool down an essential piece of equipment. We tested to see what kinds of things we could freeze and break.

            Of course, there's nothing quite like instantly frozen Reeses Peanut butter cups.
            A third party security audit is the IT equivalent of a colonoscopy. It's long, intrusive, very uncomfortable, and when it's done, you'll have seen things you really didn't want to see, and you'll never forget that you've had one.

              I think the difference is the rate at which the temperature changes. Certain materials are able to withstand a prolonged exposure to extreme cold if their temperature is lowered at a slow steady rate. Sharp drastic changes usually results poorly for metal. I'm no materials engineer but from my limited materials experience I believe this to be the case. Could be wrong though...

              Right before we left for con, we gathered up some Liquid Nitrogen we had left over and made some ice cream with it. Have to say it was probably the best ice cream I ever had and would highly suggest it to anyone looking for a way to move some liquid nitrogen...

                Yeah, that sounds a little bit harder to come by than duster

                  Depending on how fast I can get caught up with other stuff I might have some fun with a few locks and liquid nitrogen, just so I can post results and videos.

                  It's not that hard to come by if you know the right people or are good at social engineering, after all both Noid and myself ended up with a large amount of it for DC13.

                    There's an Air Products plant right up the road from my office. I know they sell it there, but not sure if the average citizen can buy it. I'm fairly certain that they'll sell Dry Ice though. You could probably set the lock on a block of that and freeze it enough to make it brittle.

                    If you can buy it from Air Products, just order some Omaha Steaks.
