Denial of Service attacks are nothing new to people in the IT and computer security world. DoS attacks are a very simplistic form of attack which aim to flood the target (whether it be a computer, mobile device, or phone line) with traffic so that it cannot process legitimate traffic. While being simple simple to perform, DoS attacks are often difficult to defend against without significant downtime.
Today I'm going to show you how to perform a DoS attack on a phone line. This process is simple, quick to perform, and very illegal. Before we get started, I'd just like to remind you that this article is for educational purposes only! All the code I'm putting into this article is python, and should work on any system with python 2.4+.
