Mounting the filesystem on your workstation

There are many ways to mount the camera’s filesystem using the firmware binary. In this post, we’ll explain one way to mount firmware version v1.00R24 which is the latest available for the WVC54GCA model. [...]

This is going to be one of these quick posts which just makes you think what the information security landscape will be like in 5 years. Before I move on with my commentary, here is a video which is essential for you to watch.

Got the idea? No! Let me explain. What you see in the video above is an application for the iPhone which gives you detailed characteristics of properties (houses) in USA. [...]

This article is a continuation of the following GNUCITIZEN articles, which include an introduction to the topic and also some initial observations: Hacking Linksys IP Cameras (pt 1), Hacking Linksys IP Cameras (pt 2), Hacking Linksys IP Cameras (pt 3).

There are two types of vulnerabilities I will be releasing today: disclosure of credentials in client-side source code and multiple XSS. [...]

Unlike the previous two vulnerabilities I released, the vulnerabilities I’m releasing in this post are perhaps not so useful to break into the device as you need access to the admin account to exploit them. [...]

Privilege escalation via arbitrary file retrieval

The second vulnerability I’ll be releasing is an arbitrary(ish) file retrieval vulnerability. It’s not fully arbitrary because you can only retrieve the contents of files located within the same directory where the vulnerable CGI program is located. [...]

During the easter break, I was playing with my my wireless Linksys IP camera which, although I bought several months ago, I hadn’t taken my time to give the attention this beauty deserves until now! :)

The model in particular is the WVC54GCA, which I would say is one of the most affordable Wi-Fi IP cameras out there (about GBP 80 in the UK), making it a great toy to tinker with. [...]

Perl, Ruby Python: use the language that suits your character. However, one of the things that differentiate python from the rest is its philosophy, which is: there should be one– and preferably only one –obvious way to do it (where it is a problem). This philosophy gives python some interesting advantages over other similar languages. That will be explained later on. [...]

You’ve already got it! It is laying on your PC and it is called the shell. The shell was designed to start/strop and control process with ease so why do we need yet another universal pen-testing framework, which does what another tool is already doing for us and it comes by default? In this post we are going to delve in the world of advanced shell programming for penetration testing purposes.

The shell is defacto the interface to your operating system. [...]

It was quite interesting to watch the presentation of Jacob Appelbaum, Dag Arne Osvik, Arjen Lenstra and several other academic and independent researchers (for the complete list go here), especially when I thought their work will be related to breaking BGP.

So it is not BGP. [...]

So let’s say that you decide to write a tool for doing some web related exploitation, enumeration, etc. The preferred language of choice comes down to perl, python ruby (C if you are an old school diehard).

It has to run from the command line. It has to have flags, etc, etc, and pretty much everything else a command line tool usually needs. [...]
