It’s been a long time since my security sprint publications I took some vacations in order to further studying, work and practice a bit more about some security areas I’ve been working on. My lasts efforts have been laid over distributed systems and how to apply security in ubiquitous networks. I aim to write a larger paper about this, but for now I’d love to share a sneak of the possibilities surrounding this interesting topic.

Divide to conquer!

Ubiquitous computing is leading us to a brand new relationship between users and...

From “you are crazy” to “why even?” are some of the things my friends in the computer science environment have told me when I started working with Haskell in general and security in particular. Answering in order, yes I’m crazy but not because of Haskell and well, there’s a reason why I chose to use Haskell for security. First of all, functional programming is the new black and probably more and more apps will be build using it. Choosing a pure functional language for security is not that crazy. On the other hand, the mathematical approaching Haskell has is very...

For the ones who are not close to security related slang, Catch The Flag is an online hacking game that consist in hacking stego, web, network, etc in order to get passwords (the flags) and catch them all before the rest of the contestants. So through three days, I played one of those organized by my university, with a team mostly dedicated in Network and Forensic study. I won’t be explaining all the process here, but I want to point out all the tools I used (most of them brand new for me) for solving the problems.

I’ve been quite in many things lately, which didn’t allow me to study all I wanted to. I’m mainly in two things, distributed ledger experiments and hardware. But I’ve had in mind a hacking experiment for quite a long time, and finally I decided to try it. It’s a Man In The Middle attack (or sniffing) over bluetooth connections using a python repository, I think I will omit for what I wanted to know that.

Anyway, what I want to do here is to catch a connection between two nodes using bluetooth....
