A few days later than planned (sorry about that), but here we go with part 2 (Part1) and the demodulation/analysis part.

Initial Analysis
To analyse a captured signal, the tool baudline seems to be the best way at the moment. So we open it with the following options and have a closer look (ContextMenu->Input->Open file):

After using the open button, you should be able to see something similar to this:

Analysis of an Alarm System – Part 1/3

Introduction
This and the following two posts should serve as a step-by-step guide through the whole process of analyzing a radio frequency black box, demodulate and understand the data transfered and finally modulate our own data in order to e.g. perform a brute force attacks.

The information provided and the results are immensely inspired by Michael Ossmann and the workshops he has given at our location. Visit him and his great tool HackRF at https://greatscottgadgets.com/hackrf/ !

ERNW’s Top 9 Burp Plugins

In the context of an internal evaluation, we recently had a look at most of the burp plugins available from the BApp store. The following overview represents our personal top 9 plugins, categorized in “Scanner Extensions”, “Manual Testing” and “Misc” in alphabetic order:

Scanner Extensions

ActiveScan++

This plugin adds some tests for Dynamic code injection, Host header attacks (password reset poisoning, cache poisoning, DNS rebinding), OS command injection and Relative path overwrite. In some internal tests, it seemed to deliver what it promises.

tsakwaf 0.9.1 released

A few weeks ago, I released version 0.9 of a web application testing tool called tsakwaf (The Swiss Army Knife for Web Application Firewalls) together with an ERNW Newsletter about web application firewalls. tsakwaf is based on perl and supports fingerprinting of some supported WAFs and code generation methods to circumvent filter rules. Today, version 0.9.1 will be released, which adds SSL support for the WAF fingerprinting function (Big thanks to Simon Rich!) and a bug fix regarding the detection of WAF reactions which may lead to false positives. Additionally, I’m happy to announce that at least one talk at next year’s Troopers will cover attacks against WAFs (like this one from the 2009 edition) . So mark your calendar – Troopers12 will happen on 21^(st) and 22^(nd) March 2012, with the usual workshops before the conference and the round table sessions the day after – and enjoy playing with tsakwaf!
