Didier Barzin
Hi there, I'm Didier, a technology and information security enthusiast. I started my career as an information security Ninja, defending information systems against cyber threats using my Jedi skills. However, I also have another side to me that comes out at night, that of a benevolent hacker. I love using my skills to support the values of open source and firmly believe in them.
I believe that technology can be used to improve people's lives, but this can only be done if we work together and share our knowledge. That's why I'm also a strong advocate of collaboration and openness in the tech industry.
May the source code be with you!

Modern infrastructures are increasingly complex, distributed, and opaque — making it difficult for security teams to answer a simple question: what exactly are we protecting?
System cartography provides an essential foundation for cybersecurity governance. It allows organizations to understand their architecture, dependencies, and data flows — the key to effective risk management, incident response, and compliance.
Does end-users spontaneously connect USB sticks fiund in public places to their personal or professional computers ?
To this end, a controlled experiment was carried out in Luxembourg, where 250 USB sticks were voluntarily “lost”. The results revealed a high success rate, estimated around 20%, with the first connection recorded in just a few minutes. We believe that these users are acting out of curiosity or altruistic intent, seeking to identify or restore the owner of the key.
However, they do not perceive the risks associated with their gesture. The study highlights the persistence of USB key attacks as an effective intrusion vector, and underscores the need to make users more aware of the dangers they represent.
