OSWE — Advanced Web Attacks & Exploitation (WEB-300)

White-box web exploitation. Source-code-driven.

OSWE is the elite web-application credential. You read source code (PHP, Java, Node.js, .NET) to find authentication bypasses, deserialization, type juggling — then chain them into RCEs. Macksofy's bootcamp covers OSWE-specific labs plus modern web research.

In short

What is the OSWE certification?

The Offensive Security Web Expert (OSWE, OffSec) is an advanced white-box web-application security certification focused on source-code review and chaining vulnerabilities into working exploits. Macksofy runs an OSWE exam-prep bootcamp with hands-on web-exploitation labs in India.

FAQ

Things students ask before enrolling.

Standard OffSec WEB-300 + 90-day lab + exam bundle is ~₹1,70,000. Through Macksofy the same official bundle — course, 90-day lab and exam voucher — is ₹1,45,000 (15% off, EMI available). The Macksofy modern-web bootcamp (GraphQL, OAuth, request smuggling) and mentor support is a separate add-on, quoted on top.
Yes — OSWE-trained hunters consistently report higher-impact findings (RCE, auth bypass, deserialization) vs generic XSS/SQLi. Most six-figure HackerOne / Bugcrowd payouts in 2024–25 came from chains that an OSWE holder can identify in source review.
Highly recommended. OSWA (WEB-200) builds the black-box methodology and OWASP-Top-10+ foundations. OSWE jumps straight into white-box source review across PHP, Java, Node.js, .NET and Python — without OSWA-level fluency the case studies become opaque.
Different products. BSCP (PortSwigger) is exam-only, methodology-focused, ~$99 — excellent ROI but does not teach white-box review. OSWE is a full course + 48-hour practical exam with source-code work and is the cert AppSec hiring managers cite. Many senior AppSec engineers hold both.
You should be comfortable reading PHP, Java, Node.js / JavaScript, .NET (C#) and Python. Macksofy's bootcamp begins with a 'language refresher' day for AppSec engineers who haven't read Java enterprise code in a while.
Senior AppSec Engineer (₹20–35 LPA), Web Pentest Lead (₹18–30 LPA) and Bug-Bounty / Vulnerability Research roles (₹25 LPA+). Top employers: Microsoft Security Response Centre, Atlassian, GitLab, Razorpay, Flipkart, ICICI, HDFC, ADGM-licensed firms.
Exam is delivered remotely with proctoring. Macksofy schedules two full mock 48-hour exams during the bootcamp so you build the endurance and note-taking discipline before exam day.
Common paths: (1) Bug-bounty specialisation; (2) Source-code-review tooling work (Semgrep, CodeQL); (3) AppSec leadership / SAMM-aligned program-building; (4) OSEP for breadth into red-team. Macksofy mentors all four trajectories.
