Drupal 8 brings radical evolution to one of the world's top open source web content management systems.

We will try and get through all the following:
  
This tutorial will give you hands on experience with the newest version of Drupal. If you haven't had a look for a while, now is the time to revisit the drupalverse.

* Introduction to Radare2 reverse engineering tool

* Basics of using the Radare to examine a binary you probably have on your laptop
 +
* Looking at an arduino binary

* Introduction to MIPS architecture and disassembly

* Extracting firmware images
  
We will build a website from scratch and learn how to participate in one of the open source world's largest communities.

You might like to bring your own binary to play with as well instead!
  
We will attempt to build a basic, responsive website from scratch in one short afternoon.

For best results, you should be prepared with an idea or three of the kind of website you want to build. Bring some content, images, or pick a favourite Lorem Ipsum generator and some sample piccies from OpenClipart.org.

Revision as of 22:35, 10 January 2015

This page describes preparation for Reverse engineering embedded software using Radare2

Outline

We will try and get through all the following:

  • Introduction to Radare2 reverse engineering tool
  • The Radare2 utilities
  • Basics of using the Radare to examine a binary you probably have on your laptop
  • Looking at an arduino binary
  • Introduction to MIPS architecture and disassembly
  • Extracting firmware images

You might like to bring your own binary to play with as well instead!

Important - please make an rc file

Radare2 was created by other, many people. Radare2 will by default print fortune cookies. Please, turn this feature off, by making the following file, in case there is a possibility of NSFW output.

Instructions for Linux/Unix systems:

   echo 'e cfg.fortunes=false' > ~/.radare2rc

Prerequisites

If during the tutorial you are planning to follow the examples and/or try your own ideas, you really want to get this sorted before the event.

Minimum requirements:

  • a C compiler and libraries needed to build radare2 - the "apt-gettable" version is out of date
  • xdot for viewing callgraphs
  • binwalk and srecord for firmware hacking

Various other tools may be helpful, and indeed needed (e.g. an editor) to complete some of the examples

If you are using a Debian-derived distro, for example:

   sudo apt-get install build-essential git xdot eog ghex binwalk vim gedit srecord

It should be possible to build radare2 on Linux, FreeBSD/NetBSD etc, Max OS/X and Windows and possibly on Android if you try hard enough (using a Debian root, for example)

However, the tutorial examples have only been tested using Debian Wheezy.

Clone & build radare2

Note, changing to the lca2015_tutorial branch is important, because the software is under active development there could be breakage in master upstream

   git clone http://github.com/pastcompute/radare2
   cd radare2
   git checkout tutorial_branch
   ./configure
   make -j
   sudo make symstall

Note, you can install as a normal user if you need to:

   ./configure --prefix=$HOME/path/to/wherever
   make -j
   sudo make symstall
   export PATH=$HOME/path/to/wherever:$PATH

Clone the examples repository, ready for use during the tutorial

   cd
   git clone http://github.com/pastcompute/lca2015-radare2-tutorial

I have already added prebuilt examples to git but there are instructions for building them in git, you will need the arduino IDE or an openwrt buildroot.

Troubleshooting

The tutorial is not until Thursday afternoon. If you need help with the above ping me on Twitter, preferably before the day! @pastcompute
