Chain findings for maximum impact. +## Core Philosophy -## Phase 1: Exhaustive Reconnaissance +**Coverage over speed**: Every single endpoint, parameter, and feature must be tested. An untested endpoint is a potential miss. -**Whitebox (source available)** -- Map every file, module, and code path in the repository -- Trace all entry points from HTTP handlers to database queries -- Document all authentication mechanisms and implementations -- Map authorization checks and access control model -- Identify all external service integrations and API calls -- Analyze configuration for secrets and misconfigurations -- Review database schemas and data relationships -- Map background jobs, cron tasks, async processing -- Identify all serialization/deserialization points -- Review file handling: upload, download, processing -- Understand the deployment model and infrastructure assumptions -- Check all dependency versions against CVE databases +**Real impact over theoretical findings**: Every reported vulnerability must have a demonstrated, concrete, real-world business impact. If you cannot demonstrate the impact, you cannot report it. -**Blackbox (no source)** -- Exhaustive subdomain enumeration with multiple sources and tools -- Full port scanning across all services -- Complete content discovery with multiple wordlists -- Technology fingerprinting on all assets -- API discovery via docs, JavaScript analysis, fuzzing -- Identify all parameters including hidden and rarely-used ones -- Map all user roles with different account types -- Document rate limiting, WAF rules, security controls -- Document complete application architecture as understood from outside +**UI-first, always**: Modern applications are built around user interfaces. API testing without UI exploration misses entire feature surfaces. The UI is the ground truth. -## Phase 2: Business Logic Deep Dive +**Recursive deepening**: One pass is never enough. The first pass finds low-hanging fruit. The second pass finds what survived basic defenses. The third and fourth passes find what only expert techniques can reach. -Create a complete storyboard of the application: +--- -- **User flows** - document every step of every workflow -- **State machines** - map all transitions (Created → Paid → Shipped → Delivered) -- **Trust boundaries** - identify where privilege changes hands -- **Invariants** - what rules should the application always enforce -- **Implicit assumptions** - what does the code assume that might be violated -- **Multi-step attack surfaces** - where can normal functionality be abused -- **Third-party integrations** - map all external service dependencies +## Phase 0: Exhaustive Intelligence & Recon -Use the application extensively as every user type to understand the full data lifecycle. +This phase builds the complete attack surface map.

At scale, an attacker could automate this for every order, paying nothing while receiving real goods or services. The company loses the full product value for every order placed this way.
