EXP-301: Windows User Mode Exploit Development (OSED)
Course Overview
EXP-301 is an intermediate course that teaches the skills necessary to bypass DEP and ASLR security mitigations, create advanced custom ROP chains, reverse-engineer a network protocol and even create read and write primitives by exploiting format string specifiers.
Windows User Mode Exploit Development (EXP-301) is a course that teaches learners the basics of modern exploit development. Despite being a fundamental course, it is at the 300 level because it relies on substantial knowledge of assembly and low level programming. It begins with basic buffer overflow attacks and builds into learning the skills needed to crack the critical security mitigations protecting enterprises. Learners who complete the course and pass the exam earn the OffSec Exploit Developer (OSED) certification. The OSED is one of three certifications making up the OSCE3 certification along with the OSEP for advanced penetration testing and OSWE for web application security. Course Objectives:
- Learn the fundamentals of reverse engineering
- Create custom exploits
- Develop the skills to bypass security mitigations
- Write handmade Windows shellcode
- Adapt older techniques to more modern versions of Windows
