GNUCITIZEN

What is the best way to spend a quiet, weekend afternoon? – Jump off a perfectly working plane while 10,000 feet in the air.

On 5th of July 2009, the GNUCITIZEN team and friends came together to perform a skydiving gig. It has been two months since that day but memories are still as clear as yesterday.

Automated Web Application Security Testing tools are in the core of modern penetrating testing practices. You cannot rely 100% on the results they produce, without considering seriously their limitations. However, because these tools are so good at picking the low-hanging fruit by employing force and repetition, they still have a place in our arsenal of penetrating testing equipment.

These tools are not unfamiliar to modern day penetration testers. [...]

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. [...]

Two of the most popular Firefox extensions are at war, fighting for their own piece of land. More examples will follow.

Oh yes, the digital battlefield is taking unusual shapes. The latest manifestation of cyber warfare is a conflict between the Adblock Plus and the NoScript extensions. The story goes that NoScript used some JavaScript tactics and, of course, some obfuscations in order to cripple the Adblock Plus functionalities. [...]

When I was playing/introducing the partial disclosure practice an year and something ago, I did get contacted by numerous dodgy characters willing to buy yet undisclosed vulnerabilities for substantial amount of money.

Of course, requests of that nature were kindly ignored. I couldn’t believe that someone was willing to give me so much money for something I virtually spent 2-3 hours maximum to produce. [...]

With this post I would like to inform you that Jeriko moved in its own source code repository which you will be able to find here. There is also a discussion group here, if you feel like using it.

The version inside the new code repository is very different from the version you’ve seen before. [...]

On the 14th this month, Computerworld published an interesting article titled ‘Mafiaboy’ spills the beans at IT360 on underground hackers. Interesting read but nothing too exciting.

The article is yet another proof that we are all in big trouble. Simply put, the technology will continue to develop and the majority of people wont be able to keep up. As long as the situation remains the same, people and corporations will get exploited regardless how tight their security is. [...]

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. [...]

This morning I spotted several blog posts mentioning that Twitter has been hit by yet another XSS worm.

There is no merit in discussing how this has been done and for what purposes but this incident is yet another proof that the attack landscape is rapidly changing and moving towards web enabled infrastructures and the client-side. [...]

I wish I had the ultimate tool, whether that is a programing language such as perl, python and ruby, or whether it is a framework like metasploit and vulnerability scanner like nessus. I wish, but I know that such thing doesn’t exist and probably never will.

Lately I’ve been dropping a lot bash scripts on public forums and of course on work related projects. Many people came back to me asking why I chose bash. Python or perl would have been better! [...]
