Excerpt

Crown Jewel Targets

Business logic vulnerabilities pay highest in platforms where financial transactions, identity verification, and access controls intersect with real-world consequences. The richest targets are:

E-commerce & payment platforms (Valve/Steam, Shopify) — payment flow manipulation, free goods, price tampering
Marketplace & gig economy apps (Airbnb, Uber) — identity/verification bypass enabling fraud or unsafe interactions
SaaS with tiered access (Mozilla Monitor) — bypassing verification to unlock monitoring features without entitlement
High-traffic consumer apps (Snapchat, Yelp) — rate-limit bypass enabling spam, enumeration, or abuse at scale
