Attacker Mindset — Web · modules
Why each web vuln class exists — trust boundaries, grammar confusion, authorization drift. Mindset first, tools second.
Module 4 · Business Logic — Where Scanners Fail
Business logic bugs are legal sequences of actions producing illegal outcomes. Understand the product to find them.
Module 5 · Why SSRF Is Still Critical in 2026
Every URL parameter where the server fetches. Cloud metadata turned SSRF from inconvenience to catastrophe.
Module 6 · Why XSS Persists — Context Is Everything
Framework defaults cover one HTML context. Every other context — URL, CSS, JSON-in-script — is fresh attack surface.
Module 7 · File Upload — Three Attacks in One
Upload = attack at parsing + storage + serving. All three have their own rules, and mistakes compound.
Module 8 · APIs — Your Mobile App Is Public Attack Surface
Every endpoint your mobile or SPA calls is exposed to the internet. Shadow endpoints, version drift, mass assignment.
Module 9 · Session Tokens — Where Auth Bugs Live After Login
Developers focus on login; attackers target sessions. Theft, rotation, revocation, and the edge cases that break.
Module 10 · The Framework-Assumption Gap
'The framework handles it' is the most dangerous phrase in modern web security. Escape hatches, third-party integrations, and non-REST transports.
Module 1 · Trust Boundaries — Where Every Web Vuln Begins
Every web vuln is a trust-boundary bug. Learn to see boundaries before learning to exploit them.
Module 2 · Why Injection Still Happens — A Grammar Problem
Injection isn't about bad input. It's attackers smuggling tokens into an interpreter's grammar.
Module 3 · Why Auth Checks Fail — Missing Gates Everywhere
Authentication is one gate. Authorization is every gate after. Most breaches live in the latter.
