A GoLang tool to enumerate and abuse LDAP. Made simple.

Ldapper was created with for use in offensive security engagements for user enumeration, group enumeration, and more. Ldapper uses familiar “net” commands such as “net user” and “net group” to perform all its queries and its output follows the same conventions. Ldapper’s user interface operates as a interactive shell, where the user can input commands until exited. All traffic goes over the LDAP(S) protocol with a singular bind to help you better blend into the network. Ldapper is proxy aware and supports NTLM authentication with a user’s hash. Additionally, this tool can perform modification actions within LDAP.

Ldapper is proxy aware and supports NTLM authentication with a user’s hash. Additionally, this tool can perform modification actions within LDAP. More functionality is planned for later releases, but for now additional supported command functions are:

This tool should be considered in its beta stages. Please report any bugs, issues, or functionality ideas for future releases.

Setting up connection

NOTE: -s enables LDAPS instead of LDAP. LDAP by default is TCP based but Microsoft tend to use UDP for LDAP. LDAPS is TCP.

Optional flags:

  • -t - Enable timestamps for each command performed
  • -s - Enable the use of LDAPS

With Password: connect -u <username@domain> -p <password> -d <ip/FQDN>

With Hash: connect -u <username@domain> -H <hash> -d <ip/FQDN>

With Kerberos: connect -u <username@domain> -k -d <ip/FQDN>
