So you want to register to CTP, eh?
The "Cracking the Perimeter" Online course is not an introductory security course. Many pre-requisites are required, such as good familiarity with a Ollydbg, and a general mastery of offensive network security techniques.
In order to register for the course you must bypass the protections implemented in this registration form and obtain a 16 Byte Registration Code . You will get further instructions once you obtain the registration code.
Use of automated scanners will result in a 3 minute block from the website. No exploitation or vulnerability scanning is required to bypass the form. Use the source Luke!
