Hello there,

I’m f0o (AKA Daniel Preussker), I’ve been surrounded by computers my entire life.

I’m son of an old fashioned hacker and I’ve been around cryptography and network security as well as enterprise level core development for +5 years now.

My primary focus relies on offensive security and computer forensics but I also find fun in cryptographic analysis and overall all network monitoring, if you know what I mean

I’ve worked as programmer and penetration tester and now try to make a living as security consultant. Yet I’m doing my under-degree at this very moment… urgh…

You might know me from EFnet, Full-Disclosure, Launchpad, GitHub, Google+, Facebook, Skype, …
