EXP-301
Offensive Security Exploit Developer (OSED)
About the Certification
This is an advanced professional certification from Offensive Security specialized in Exploit Development, focusing on the deep technical aspects of memory-based attacks and bypassing modern protection mechanisms. The certification aims to prepare candidates to understand program internals, analyze vulnerabilities, exploit memory corruption flaws, and develop custom exploits using low-level tools and techniques, while bypassing protections such as DEP and ASLR. It is heavily hands-on and analysis-driven, making it suitable for cybersecurity professionals and Red Team members seeking deep specialization and expert-level work within advanced enterprise environments.
