# SKILL: JWT and OAuth 2.0 Token Attacks — Expert Attack Playbook

> **AI LOAD INSTRUCTION**: Expert authentication token attacks. Covers JWT cryptographic attacks (alg:none, RS256→HS256, secret crack, kid/jku injection), OAuth flow attacks (CSRF, open redirect, token theft, implicit flow abuse), PKCE bypass, and token leakage via Referer/logs. This is critical for modern web applications.

## 0. RELATED ROUTING

Use this file for token-centric attacks and flow abuse. Also load:

- [oauth oidc misconfiguration](../oauth-oidc-misconfiguration/SKILL.md) for redirect URI, state, nonce, PKCE, and account-binding validation
- [cors cross origin misconfiguration](../cors-cross-origin-misconfiguration/SKILL.md) when browser-readable APIs or token leakage may exist cross-origin
- [saml sso assertion attacks](../saml-sso-assertion-attacks/SKILL.md) when the target uses enterprise SSO outside OAuth/OIDC
