RPISEC/MBE: writeup lab04 (Format Strings)

In the last lab, which writeup can be found here, we used publicly available shellcodes as well as shellcodes we had to write on our own, in order to exploit the provided binaries. In this writeup we proceed with the next lab, which focuses on the subject of Format Strings.

As usual there are three levels ranging from C to A:
–> lab4C
–> lab4B
–> lab4A

RPISEC/MBE: writeup lab03 (Shellcoding)

The last writeup for RPISEC/MBE lab02 dealt with the subject of Memory Corruption. We used different buffer-overflow vulnerabilities to execute a predefined function shell, which kindly spawned a shell for us. In real life there usually isn’t such a function, we can simply call. Thus we have to inject our own code. Accordingly the next lab described in this writeup brings up the topic of Shellcoding.

Yet again there are three levels ranging from C to A:
–> lab3C
–> lab3B
–> lab3A

RPISEC/MBE: writeup lab01 (Reverse Engineering)

RPISEC is the resident computer security club at Rensselaer Polytechnic Institute. They developed a university course to teach skills in vulnerability research, reverse engineering and binary exploitation. The course material can be found on github including a detailed explanation on how to run the provided VM: https://github.com/RPISEC/MBE.

This article contains my writeup for the first lab (lab01). The lab’s topic is Reverse Engineering and it consists of the following levels:
–> lab1C
–> lab1B
–> lab1A
