I will continue to build upon everything we have seen and learned in the previous tutorials. While the first tutorials were really written to learn the basics about exploit development, starting from scratch (targeting people without any knowledge about exploit development) you have most likely discovered that the more recent tutorials continue to build on those basics and require solid knowledge of asm, creative thinking, and some experience with exploit writing in general. I discussed direct RET overflows, SEH based exploits, Unicode and other character restrictions, the use of debugger plugins to speed up exploit development, how to bypass common memory protection mechanisms and how to write your own shellcode. In the previous tutorials, I have explained the basics of stack based overflows and how they can lead to arbitrary code execution.
About 3 months after finishing my previous exploit writing related tutorial, I finally found some time and fresh energy to start writing a new article.
