Hakin9 X Hackathology

This past week, i was invited by hakin9 magazine to write an article about the lastest hacking skills. I am still thinking about a topic to write. There are different types of hacks and i am in a dilemma in choosing one. After pondering for sometime, i think i would love to write hacks about VoIP. Personally, because VoIP is a subset of network security, i think its best to write something that i am good at. I had already setup a PBX server and now its up to the guys at hakin9. The hakin9 team is a bunch of really cool and nice guys. They gave me a free copy of their magazine and once my article is published, they will also send me a copy of the published issue. I will keep you guys updated on this. Let me know what you guys think?
