# SAML SSO Attack Skill
SAML Single Sign-On attack methodology — IdP metadata analysis, XML Signature Wrapping (XSW), signature stripping, comment injection in NameID, and SSO timing-based user enumeration. Confirmed on TARGET_ORG_A (SimpleSAMLphp IdP, 79 XMLRPC methods on WordPress SP), TARGET_ORG_B (Ory Kratos + OIDC), and TARGET_ORG_C (ADFS WS-Trust exposed).
## When to Use
- Target uses SSO (redirects to `idp.`, `sso.`, `login.`, `auth.` subdomains).
- URL contains `SAMLRequest=` or `SAMLResponse=` parameter.
- Metadata endpoint accessible at `/saml2/idp/metadata.php` or `/FederationMetadata/2007-06/FederationMetadata.xml`.
- After `exchange-owa-attack` discovers ADFS.
## Prerequisites
- curl, python3.
