Prior knowledge for OSEP (Guide)
This is a repository of notes and material that I consider necessary in advance to opt for the course and the OSEP certification (Techniques of Evasion and Breaching Defenses)
This compilation of material is very much influenced by nullg0re (GIT) and more!
Contents
Programming languages
For this certification it is very important to have a knowledge base in the following programming languages:
