This talk focuses on the shellcode perspective and it’s evolution. From the simplest {shell}code to the polymorphism to bypass filters and I{D|P}S (which has lots of new ideas, like application-specific decoders, decoders based on architecture-instructions, and many others), passing through syscall proxying and injection, this talk will explain how it works and how effective they are against the new evolving technologies like network code emulation, with live demonstrations. There is long time since the first paper was released about shellcoding. Most of modern text just tries to explain the assembly structure and many new ideas have just been released as code, never been detailed or explained. The talk will try to fix this gap, also showing some new ideas and considering different architectures.
