The OSED | Windows User Mode Exploit Development (EXP-301) training at WebAsha Technologies in Pune is OffSec's Windows exploit-development certification, delivered through EXP-301: Windows User Mode Exploit Development - where you learn to build exploits from the ground up.

You will master low-level offensive engineering: the x86 architecture and WinDbg, exploiting stack overflows and SEH overflows, using IDA Pro, writing egghunters to overcome space restrictions, creating custom shellcode, reverse engineering binaries to find vulnerabilities, and bypassing modern mitigations such as DEP and ASLR, plus format-string attacks.

The certification is earned in a demanding 47-hour-45-minute hands-on exam of three exploit-development tasks (solve at least two; pass mark 60 of 100) and it never expires. OSED is one of the three certifications that together earn the elite OSCE³ credential. WebAsha's trainers build genuine exploit-writing skill.

Master windows user mode exploit development (exp-301) with our Classroom and Online OSED Training at WebAsha Technologies. It builds the hands-on, 'Try Harder' skills validated by the OSED exam.

Training Overview:

is OffSec's exploit-development certification, earned through the EXP-301 course. It builds the ability to reverse engineer Windows binaries and write custom exploits from scratch - stack and SEH overflows, egghunters, custom shellcode, reverse engineering for bugs, and bypassing DEP and ASLR - proven in a 48-hour hands-on exam. OSED is one of the three certifications behind the elite OSCE³ designation.

Intended Audience:

This course is ideal for penetration testers, reverse engineers, vulnerability researchers and offensive-security engineers who want to learn Windows exploit development and target the OSED certification.

Topics Covered:
  • x86 & WinDbg: Assembly and debugging.
  • Stack Overflows: Classic memory corruption.
  • SEH Overflows: Structured exception handler attacks.
  • IDA Pro: Static reverse engineering.
  • Egghunters: Overcoming space restrictions.
  • Custom Shellcode: Writing your own payloads.
  • Reverse Engineering: Finding bugs in binaries.
  • Mitigation Bypass: Defeating DEP and ASLR.
Requirements:

Comfort with Linux and the command line is recommended. Online participants need a stable internet connection and a laptop/desktop for the live labs.

Pre-Requisites:

There is no formal prerequisite. OffSec recommends familiarity with a debugger (WinDbg, Immunity or OllyDbg), basic 32-bit exploitation concepts, Python 3 coding ability, the ability to read C, and an understanding of 32-bit x86 assembly.

Career Benefits:

Exploit development is a premium specialisation. In India, OSED-certified professionals typically earn ₹8 LPA to ₹42+ LPA in research and advanced offensive roles.

Sales ExecutiveCyber Security Engineer
After a few years as a Sales Executive, I decided it was time for a real change and joined WebAsha's OSED EXP-301 Windows User Mode Exploit Development training. The placement team actively shared openings and coached me through resume building and every interview. Cloud labs, recorded sessions and after-hours doubt support meant I could learn seriously alongside my job. Today I proudly work as a Cyber Security Engineer at HCLTech, and the jump from 3 LPA to 6.5 LPA still feels surreal.

Network Support TraineePenetration Tester
Coming from a Network Support Trainee background, switching felt risky, but WebAsha's OSED EXP-301 Windows User Mode Exploit Development course gave me a clear path forward. The hands-on labs and live projects around ethical hacking, reconnaissance, scanning, exploitation and penetration testing in a safe lab rebuilt my confidence from the ground up. Cloud labs, recorded sessions and after-hours doubt support meant I could learn seriously alongside my job. Within a few months I moved from Network Support Trainee to Penetration Tester at Coforge, and my package grew from 4 LPA to 8 LPA.

I joined WebAsha for OSED EXP-301 Windows User Mode Exploit Development to level up my skills, and the experience exceeded my expectations. I could choose between online and classroom training, and both were equally well organised. Each module built logically, and the coverage of ethical hacking, reconnaissance, scanning, exploitation and penetration testing in a safe lab was thorough and current. The knowledge and confidence I gained here continue to help me every day at work.

WebAsha's OSED EXP-301 Windows User Mode Exploit Development training turned a tough certification into an enjoyable learning experience.
