What You'll Learn

Web Fundamentals & Recon
How HTTP requests, responses, cookies, headers, and sessions actually work from an attacker's view. Mapping an application's attack surface through content discovery, parameter analysis, and directory brute-forcing. Setting up Burp Suite as an intercepting proxy and using Repeater, Intruder, and Decoder. Understanding same-origin policy, CORS, and the browser security model.
Injection Attacks
Discovering and exploiting SQL injection: UNION-based, error-based, and blind (boolean and time-based) techniques, with sqlmap automation. OS command injection and how to chain it to code execution. Cross-site scripting (XSS): reflected, stored, and DOM-based, including filter bypasses. Introduction to server-side template injection (SSTI) and its path to RCE.
Authentication & Session Flaws
Attacking login mechanisms: credential stuffing, brute-force, and username enumeration. Exploiting weak password-reset flows, predictable tokens, and flawed multi-factor logic. Session management issues: session fixation, weak cookies, and missing HttpOnly/Secure/SameSite flags. Attacking JWTs through algorithm confusion, weak secrets, and signature-stripping.
Access Control & Business Logic
Finding broken access control: insecure direct object references (IDOR) and horizontal and vertical privilege escalation. Forced browsing and parameter tampering to reach restricted functionality. Exploiting business-logic flaws such as price manipulation and workflow bypasses. Mass assignment and over-permissive API endpoints.
Advanced Server-Side Attacks
Server-side request forgery (SSRF) and pivoting into internal services and cloud metadata endpoints. XML external entity (XXE) injection for file read and SSRF. Insecure deserialization leading to remote code execution. File-upload vulnerabilities and bypassing content-type and extension filters.
APIs, Reporting & Methodology
Testing REST and GraphQL APIs, including introspection abuse and broken object-level authorization. CSRF, clickjacking, and modern defenses like SameSite and CSP. Building a repeatable testing methodology aligned to the OWASP Web Security Testing Guide. Writing a professional penetration-test report with clear risk ratings and remediation advice.

Loved by hackers. Trusted by organizations.
Aditya Kulkarni
Penetration Tester
★★★★★

The injection and SSRF modules were brutal in the best way. I went from guessing to having a real, repeatable testing methodology.

Meera Pillai
Application Security Engineer
★★★★★

Finally a course that makes you actually exploit the OWASP Top 10 instead of just reading about it. Burp Suite finally clicked for me.

Harsh Agarwal
Security Consultant
★★★★★

The access-control and business-logic sessions taught me the bugs that automated scanners always miss. Immediately useful on client engagements.

Nandini Shetty
Bug Bounty Hunter
★★★★★

I landed my first valid IDOR and JWT findings within weeks of finishing. The lab targets mirror real-world apps really well.

Rahul Verma
VAPT Analyst
★★★★★

The report-writing module set this apart. Learning to communicate risk and remediation made me far more valuable to my team.
