On Friday I gave a talk to OKC's DC405 group on Metasploit and reverse tunneling out of strict network environments using PassiveX payloads. Unfortunately, we ended up without an available projector, so I gave the presentation by having everyone load it up on their laptops, using this blog and twitter to kick out links. :)
All in all, it was a great group and spawned an impressive discussion afterwards. Thanks #dc405 for letting me come be a part of the group!
