m365-entra-attack
Microsoft 365 / Entra ID red-team attack chain — current 2026 reality. AADSTS code reference, user enumeration vectors (with hardening status), Smart Lockout math, Conditional Access bypass options, ROPC + SAML SSO browser flow, Burp/Playwright templates. Built from authorized red-team work where ROPC spray surfaced pre-existing lockouts and CA-blocked credentials, plus real-time external attacker activity correlation. Use for any M365/Entra credential attack, password spray, user enumeration, CA-bypass exploration, or active-attacker-detection scenario.

## When to use this skill
Trigger when:
- Target uses M365 / Entra ID (autodiscover.* records, login.microsoftonline.com redirects, "Microsoft Office 365" in tech-stack notes)
- You have a list of corporate emails or stealer-leaked creds
- Engagement involves "credential spray", "password spray", "Entra attack", "ATO via M365"
- You see `*.onmicrosoft.com`, `*-my.sharepoint.com`, `enterpriseregistration.*`, `enterpriseenrollment.*` in recon
- Client mentions "Conditional Access", "MFA bypass", "compliant device"
DO NOT use for:
- On-prem-only Active Directory (use a separate AD-attack skill)
- Service-to-service token attacks (different threat model)
- Phishing-required attack chains (covered by phishing skills) — but you can prep for the credential-validation step here
