## What it is
A Python toolkit for abusing Kerberos in Active Directory environments, including Kerberos relaying and unconstrained delegation attacks. It bundles tools like addspn.py for SPN manipulation and dnstool.py for modifying AD-integrated DNS records over LDAP.

## Use cases
- abuse unconstrained delegation in active directory
- relay kerberos authentication attacks
- add or remove SPNs on AD accounts via LDAP
- modify active directory integrated DNS records
- capture and relay TGT tickets for privilege escalation
- red team active directory attack toolkit

## When to choose
- you are performing authorized penetration tests or red team engagements against Active Directory
- you need to demonstrate Kerberos relaying or delegation abuse risks
- you want to manipulate SPNs or AD DNS records programmatically over LDAP

## When to avoid
- you need defensive monitoring rather than offensive tooling
- you are not working with Windows Active Directory environments
- unauthorized use - this is an attack toolkit, not an administration utility
