The last weekend I put my black hat on again. I was teaching network security at Master on Free Software talking and showing a lot of different and effective attacks targetting current networks with very practical examples.
Now, people attending those classes know about tactics and tools used by blackhats while breaking in real targets. We focused on different topics such as design flaws, protocol weakness, hijacking connections, fragmentation attacks, active/passive fingerprinting, switched sniffing, MITM attacks, advanced scanning and so far.
The next master class, scheduled on the 18th/July, we'll see advanced and strategic defense for organizations. Among the practices we're going to analyse real attacks and play dynamics group.
