The WEB-200 (OSWA) course from OffSec is a specialized training program designed to teach foundational black box web application penetration testing. Unlike its advanced counterpart, the OSWE, which focuses on white box (code-level) analysis, the OSWA focuses on finding vulnerabilities from the perspective of an external attacker without access to the source code. What You’ll Master in WEB-200

  1. Open Burp → capture any .NET app request
  2. Manually decode ViewState (no tools first)
  3. Inject a test payload (sleep 5)
  4. Repeat with different gadget chains

The official delivery includes videos, a lab network (the infamous OffSec Proving Grounds), and the holy grail: the official course PDF.

Why Choose Web200 Offensive Security PDF?

In today's digital landscape, web application security is more crucial than ever. As technology advances, so do the threats and vulnerabilities that can compromise your online presence. To stay ahead of the game, it's essential to have a solid understanding of offensive security and how to protect your web applications from potential attacks.

This visual, static layout allows your brain to process complex attack chains faster than dynamic video playback.

To make your WEB-200 (OSWA) report better, focus on reproducibility and professional formatting. Offensive Security (OffSec) evaluates reports based on whether a reader can follow your steps to recreate the compromise exactly. 📄 Essential Reporting Requirements Format: Must be a PDF file.

Handling PDFs is a major attack vector in web security. Many applications accept PDF uploads or generate PDFs (reports, invoices) without proper sanitization, leading to Server-Side Request Forgery (SSRF), Stored XSS, or Malware hosting.
