This talk will be about the art of creating backdoors. Starting with automated shell scripts as an example, moving quickly to suid-exec wrappers and finally an introduction into writing kernel modules, and modifying existing ones using Linux in this case. In this talk there will be non-public code written especially for the talk. I'm not sure if this is for the haxors or the uber haxors. Probably uber haxors, as you'd need to at least be able to read some C, and the major focus will be on Linux kernel module creation and modification.
