Radare

This post is to outline the work completed during the Google Summer of Code 2015 (GSoC) period and show you a glimpse of radeco and where we are heading with it. For those who are not aware, radeco is a decompiler framework that is developed and maintained by the radare

Introduction Lot of malware/PUP (Potential Unwanted Programs)/Adwares are now digitally signed.

As you know, we have 2 students working on r2 for the Google Summer of Code! As we're 3 weeks into the Summer, here's what one of our student, sushant94 has to say about what he's been working on! It's been three weeks into GSoC and I'm having an amazing

Today, we're releasing a new version of radare2, the 0.9.9, codename Almost There. Since you might be a bit too lazy to read every single commit, we're going to highlight some cool new features! Numbers Thanks to more than 50 contributors who issued something like 1700 commits, here

In previous blog posts we've shown how radare2 can be useful for exploiting "baby" level challenges. Let's show how we can use it to find the bug and ultimately exploit a 5 point pwning challenge from the DEFCON 2015 qualifiers! You can find the binary here if you want to

In order to content the people that wanted something less hand-holding than this writeup which they say is too detailed and this one not enough, we decided to write this blogpost: not too short, not too long, and about pwning! The binary was a challenge (called baby_rop) from a
