README

Excerpt

13. ATO — ACCOUNT TAKEOVER TAXONOMY

9 distinct paths. ATO is a destination class, not a single bug — each path below is a primitive that becomes Critical only when you demonstrate takeover of a SECOND account (test account B) you do not control, from attacker A's session/IP/device. A path that only locks you out of your own account, or only works when you already hold the victim's password AND session, is not a standalone ATO.

This is the opening of the README. Read the full README on GitHub.
