WATOBO – the unofficial manual
WATOBO is intended to enable security professionals to perform highly efficient (semi-automated) web application security audits.

WATOBO has no attack capabilities and is provided for legal vulnerability audit purposes only. It works […]

Exploit writing tutorial part 10 : Chaining DEP with ROP – the Rubik’s[TM] Cube
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.
In the previous tutorials, I have explained the basics of stack based overflows and how they can lead to arbitrary code execution.

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.
Today’s tutorial is no different. I will continue to build upon everything we have seen and learned in the previous tutorials. Today I will talk about ROP and how it can be used to bypass DEP (and ASLR)…

Blackhat Europe 2010 Barcelona – Day 10
I got up early this morning, trying to be sharp and well prepared for day 2 of the BlackHat briefings. As some of you may know, I’m not really a morning person, so I usually need some time to wake up and wait until all components in my body start functioning again. After one day […]
