Hacker Fundamentals: A Tale of Two Standards

If you read my article on the OSI model, you got a good overview on communications from that model's perspective, but how does that relate to TCP/IP?

If you want to hijack sessions and all sorts of lulz like that, you need to understand these concepts. Let's get into it, mates!

News: GarageBand Changed How My Autistic Son Interacts with the World

My autistic son loves music. One afternoon, when he was nine, I downloaded GarageBand to his iPhone to help with the boredom of a long wait at a doctor's office.

How To: Use Traffic Analysis to Defeat TOR

As was mentioned by the great OTW last week, TOR, aka The Onion Router, has had its integrity attacked by the NSA. In an attempt to reduce the anonymity granted by the service, the NSA has opened a great many nodes of their own. The purpose is presumably to trace the origin of a communication by compromising some entrance and exit nodes. Once both are compromised, it is much easier to correlate traffic with a particular individual.
