I recently found this magnetic attack on the net and was a little surprised. But not a lot surprised. Security is a very funny thing. It can and is being argued that simply exposing methods such as these on the net is considerably altering the actual security of the device in question. And it is a good argument. Another somewhat similar example is whether or not knowing the correct procedure for dialing a combination then becomes part of the security of the devise. I have NO doubt there have been cases where burglars have come into the possession of a safe combination but lacking the correct dialing sequence have failed in gaining access. I have read that bump keys have been known for 50 years. I would say that this technique goes back way further than that but because it did not become popular knowledge it never became an issue. A method to aid in the manipulating a certain brand of very popular lock that has been around for a very long time came to my attention only recently. The evolution of locking devices is filled with examples of those that are good until they are beaten. In some cases it happens very quickly and in others a very long time. Most of the pressure on improvement used to come from the competition. Now it comes mostly from lock sport clubs. In the real world most of the serious threats were not and are still not a newly found slick method. I am not saying that you should stick your head in the sand but the reality is that locks work until they don't. Personally I have always been amazed that the Simplex has been seen used in security situations that shocked me but then again security like beauty is in the eye of the beholder.
