DEFCON 19: Introduction to Tamper Evident Devices


Tamper evident technologies are quickly becoming an interesting topic for hackers around the world. DEF CON 18 (2010) held the first ever "Tamper Evident" contest, where contestants were given a box sealed with a variety of tamper evident devices, many of which purport to be "tamper proof." All of these devices were defeated, even by those with little experience and a limited toolkit. Like the computer world, many of these devices are overmarketed and it is difficult for the average person to compare different tamper evident technologies.

This talk covers the design and uses of tamper evident devices used in the commercial and government sectors. We'll dig into the nitty gritty of how many of these devices work, the methods by which they can be defeated, and live demonstrations of defeats against common tamper evident devices. Be advised: this talk is for only the stealthiest of ninjas; pirates need not apply.
