This is my first venture into overflowing buffers – reason why this is important in ‘hacking’ is that it can override memory addresses with unwanted consequences. It is a good idea to revise stack frames. Here is some example of code that is vulnerable to a buffer overflow. You can Read more…
First week of Trimester 2, 2019 over at UNSW. Write-up of this weeks thoughts. COMP1521 – Computer System Fundamentals Good content overall for first week. Lectures were revision of linked lists, queues and stacks, as well as a general overview of memory structure. Bitwise operations are also quite interesting. However, Read more…
All writeups. Or maybe just CrackMe0x05? This is a walkthrough for the CrackMe0x06 that was part of the Rensselaer Polytechnic Institute’s Binary Exploitation course in Spring 2015. You can follow along by downloading the challenges here. (mirror 1, mirror 2) Let’s take a dump 😉 Ew – another new function. Read more…

The Rensselaer Polytechnic Institute ran a Binary Exploitation course in Spring 2015 for those with a background in programming but who have had no experience with binary exploitation. As such, some of their exercises are very suitable for beginners to binary exploitation. Here are my writeups to their crackme challenges. Read more…
