The Offensive Security Web Expert (OSWE) certification, part of the WEB-300: Advanced Web Attacks and Exploitation (AWAE) course, remains one of the most prestigious credentials for advanced web application security as of 2026. Unlike foundational certifications that focus on network entry, the OSWE is a 100% white-box challenge focused on deep source code analysis and vulnerability chaining. 2026 Certification Overview
Focus: Advanced white-box testing, source code review, and crafting fully automated, non-interactive exploit scripts.
Target Audience: Senior penetration testers, application security (AppSec) specialists, and developers.
Validity: The OSWE is a lifetime certification that does not expire. Exam Format and Requirements
The OSWE exam is notoriously demanding, designed to test a "Try Harder" mindset over a multi-day period. Advanced Web Attacks and Exploitation OSWE Exam Guide
I’m unable to provide or link to a PDF copy of the OSWE (Offensive Security Web Expert) certification materials, including any “new” editions, course guides, or deep-dive essays that reproduce proprietary content from Offensive Security. These materials are copyrighted and legally protected.
However, I can offer a detailed, original deep-dive essay on what the OSWE certification represents, its core focus, how it differs from the OSCP, and the key techniques covered in the latest exam version (WEB-300 / WEB-300+). This essay is entirely original and follows the spirit of advanced web application security testing without infringing on OffSec’s proprietary content.
OffSec has dramatically improved their DRM. The new course is streamed via the OLL portal. While you can print to PDF, those files are watermarked with your name. If leaked, OffSec will ban your student number and potentially revoke existing certifications. No legitimate professional risks that.
| Week | Focus | Practical Exercises (public) |
|------|-------|-----------------------------|
| 1–2 | PHP code review | PortSwigger: PHP deserialization, OS command injection; PentesterLab: PHP code review (bad use of system) |
| 3–4 | Java (Spring) | PortSwigger: EL injection, SpEL RCE; GitHub repos with vulnerable Spring apps (e.g., "vuln-spring") |
| 5–6 | C# ASP.NET | TryHackMe "ASP.NET deserialization"; HackTheBox "Json" (deserialization chain) |
| 7–8 | Python web | PortSwigger: Server-side template injection (Jinja2); Pickle RCE challenges |
| 9–10 | Node.js | Prototype pollution labs (PortSwigger); Command injection in Node |
| 11–12 | Chaining + full apps | VulnHub/HTB machines that require white-box approach (e.g., "Wombo", "Tomghost" – but adapt to OSWE style) |
Since you are looking for new resources, here is the official and unofficial curriculum for the modern OSWE.
Searching for a "new OSWE PDF" is a sign of a dedicated student looking for resources, but it’s a shortcut that won't help you in the exam room. The OSWE is an elite certification because it forces you to think like a developer and an attacker.
If you are serious about becoming an Offensive Security Web Expert, invest in the official training, sharpen your Python skills, and prepare to read a lot of code. There are no PDF shortcuts to expertise.

Offensive Security Web Expert (OSWE) is an advanced certification that marks a transition from black-box automated testing to deep, white-box source code analysis. Unlike foundational certifications that emphasize network exploitation, OSWE focuses on the "mile-deep" specialization of web application security. The Core Philosophy: White-Box Analysis The fundamental differentiator of the OSWE is its focus on source code review
. Candidates are not just looking for exposed services; they are given access to the application's entire codebase across various languages like Java, .NET, PHP, Python, and JavaScript
. The goal is to identify subtle logic flaws, insecure configurations, and complex vulnerabilities—such as deserialization prototype pollution type juggling —that automated scanners typically miss. The WEB-300 Course and Materials The journey toward OSWE begins with the WEB-300 (Advanced Web Attacks and Exploitation) course. The official materials typically include: comprehensive PDF guide
(roughly 270+ pages) providing step-by-step instructions on exploiting vulnerable lab applications. 6 hours of video content and a dedicated virtual lab environment. 17 in-depth modules
and 20 "Challenge Labs" designed to simulate real-world vulnerability scenarios. The 48-Hour Practical Exam
The OSWE exam is renowned for its intensity, requiring candidates to remain focused over a 47-hour and 45-minute proctored session. To pass, candidates must:
