Exploit writing tutorial part 6 : Bypassing Stack Cookies, SafeSeh, SEHOP, HW DEP and ASLR

Published September 21, 2009 |

Introduction In all previous tutorials in this Exploit writing tutorial series, we have looked at building exploits that would work on Windows XP / 2003 server. The success of all of these exploits (whether they are based on direct ret overwrite or exception handler structure overwrites) are based on the fact that a reliable return […]

Exploit writing tutorial part 5 : How debugger modules & plugins can speed up basic exploit development

Published September 5, 2009 |

In the first parts of this exploit writing tutorial, I have mainly used Windbg as a tool to watch registers and stack contents while evaluating crashes and building exploits. Today, I will discuss some other debuggers and debugger plugins that will help you speed up this process. A typical exploit writing toolkit arsenal should at […]

Exploit writing tutorial part 2 : Stack Based Overflows – jumping to shellcode

Published July 23, 2009 |

By Peter Van Eeckhoutte (corelanc0d3r)

Where do you want to jmp today ? In one of my previous posts (part 1 of writing stack based buffer overflow exploits), I have explained the basisc about discovering a vulnerability and using that information to build a working exploit. In the example I have used in that post, we have seen that ESP […]
