OffSec EXP-301 Windows User Mode Exploit Development

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.

 

Benefits

Learners will:

  • 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

 

Who is this course for?

  • Windows User Mode Exploit Development is an intermediate course designed for those who want to learn about exploit development skills
  • Job roles like penetration testers, exploit developers, security researchers, Malware analysts, and software developers working on security products, could benefit from the course

 

Exam
