Reverse Engineering With Radare2 – Part 3

Sorry about the larger delay between the previous post and this one, but I was very busy the last weeks.
(And the technology I wanted to show wasn’t completely implemented in radare2, which means that I had to implement it on my own 😉 ). In case you’re new to this series, you’ll find the previous posts here.

As you may already know, we’ll deal with the third challenge today. The purpose for this one is to introduce
some constructs which are often used in real programs.

Reverse Engineering With Radare2 – Part 2

Welcome back to the radare2 reversing tutorials. If you’ve missed the previous parts, you can find them here and here.

Last time we’ve used the rabin2 application to view the strings found inside the challenge01 binary to find password candidates. Based on the results we looked into the assembly to find the correct password. In this post, we’ll go through the next challenge and try out some of the features provided by radare2.

Reverse Engineering With Radare2 – Part 1

Welcome back to the radare2 reversing tutorials. If you’ve missed the intro, you can find it here.

The last time you got the challenge01 binary and your goal was to find the password for the login. Let’s see how the application looks like:

Reverse Engineering With Radare2 – Intro

As some of you may know, there is a “new” reverse engineering toolkit out there which tries to compete with IDA Pro in terms of reverse engineering. I’m talking about radare2, a framework for reversing, patching, debugging and exploiting.

It has large scripting capabilities, runs on all major plattforms (Android, GNU/Linux, [Net|Free|Open]BSD, iOS, OSX, QNX, w32, w64, Solaris, Haiku, FirefoxOS and even on your pebble smartwatch 😉 ) and is free.

Sadly, I had some problems finding good tutorials on how to use it, as the interface is currently a bit cumbersome. After fiddling around, I’ve decided to create a little tutorial series where we can learn together ;). Continue reading “Reverse Engineering With Radare2 – Intro”
