# Kerberoasting & AS-REP roasting

## When it applies
You have valid domain credentials (kerberoasting) or just a username list (AS-REP). Both recover
plaintext passwords offline by cracking Kerberos-issued material — no lockout risk.

## Why it works
- **Kerberoasting**: any authenticated user can request a service ticket (TGS) for any account
  with an SPN; part of it is encrypted with the service account's password hash. Crack it offline.
- **AS-REP roasting**: accounts with "do not require Kerberos preauth" hand out an AS-REP
  encrypted with the user's key to *anyone* — no creds needed, just the username.

## Method
1. **Kerberoast** (need creds): `impacket-GetUserSPNs corp.local/user:pass -dc-ip DC -request`
