OffSec Exploit Developer (OSED)

Sheng-Chuan Huang

OffSec Exploit Developers (OSEDs) have the skills and expertise necessary to write their own shellcode and create custom exploits from scratch. They can use these exploits to reverse-engineer bugs and bypass common Windows security mitigations. OSEDs can: * Bypass basic security mitigations such as DEP and ASLR * Exploit format string specifiers * Find bugs in binary applications to create custom exploits They are able to adapt older exploitation techniques to more modern versions of Windows and execute them at a higher level than an OSCP. The OSED certification is one part of the updated, three-part OSCE cert.
