Bio

Adrianus has been examining the way things work on the Internet for almost 30 years. Being a hacker to his most very core, he employed anything from programming ‘alternatives for intended operational use’ to becoming an entrepreneur and pioneer, in that he set up firsts in web hosting, ISP’s in Africa and large scale ISP’s in Europe, just for the sake of quenching his thirst for knowledge.

Nowadays he likes to divide his time between educational efforts and taking on cutting edge challenges.

Currently he works, amongst others, at RedSocks B.V. as Security Evangelist and scientist in the development of the malicious threat detection systems.

Identity and Security

Below is my PGP Public Key, but I can not guarantee that you will see this unmodified (there might be caches between your browser and my server that modify this), but it is better than nothing.

The better way of course is to directly retrieve my public key from one of these keyservers:

certserver.pgp.com
pgp.mit.edu
pool.sks-keyservers.net

Failing that, use the ASCII block below. Do copy the — lines as well. (You must remove whitelines first)
