EXP-301 (OSED)
About this training
EXP-301 is OffSec's Windows user-mode exploit development course, teaching how to bypass modern security mitigations such as DEP and ASLR to build custom exploits. The course is substantial, spanning 13 modules with extensive hands-on labs covering reverse engineering, shellcode writing, and real-world exploitation techniques against Windows targets.
It leads to the OSED (OffSec Exploit Developer) certification, whose exam requires independently completing exploit development tasks in a proctored environment. The course expects a strong existing background in penetration testing, programming, and debugging tools, making it one of OffSec's more advanced technical offerings, relevant for roles like exploit developer and vulnerability analyst.
