Python3 implementation of an improved [ADRecon](https://github.com/sense-of-security/ADRecon) for Pentesters and Blue Teams. 

> ADRecon is a tool which gathers information about MS Active Directory and generates an XSLX report to provide a holistic picture of the current state of the target AD environment.

> [!TIP]
> If you are a Red Team, may check out [ADRecon-ADWS](https://github.com/l4rm4nd/PyADRecon-ADWS) instead.

## Installation

````bash
# stable release from pypi
pipx install pyadrecon

# latest commit from github
pipx install git+https://github.com/l4rm4nd/PyADRecon
````

Then verify installation:

````bash
pyadrecon --version
````

> [!TIP]
> For Windows, may read [this](https://github.com/l4rm4nd/PyADRecon/tree/main/windows). NTLM + Kerberos supported.

Examples:
  # Basic usage with NTLM authentication
  pyadrecon.py -dc 192.168.1.1 -u admin -p password123 -d DOMAIN.LOCAL

  # With Kerberos authentication (bypasses channel binding)
  pyadrecon.py -dc dc01.domain.local -u admin -p password123 -d DOMAIN.LOCAL --auth kerberos

  # With Kerberos using TGT from file (bypasses channel binding)
  pyadrecon.py -dc dc01.domain.local -u admin -d DOMAIN.LOCAL --auth kerberos --tgt-file /tmp/admin.ccache

  # With Kerberos using TGT from base64 string (bypasses channel binding)
  pyadrecon.py -dc dc01.domain.local -u admin -d DOMAIN.LOCAL --auth kerberos --tgt-base64 BQQAAAw...

  # Only collect specific modules
  pyadrecon.py -dc 192.168.1.1 -u admin -p pass -d DOMAIN.LOCAL --collect users,groups,computers

  # Output to specific directory
  pyadrecon.py -dc 192.168.1.1 -u admin -p pass -d DOMAIN.LOCAL -o /tmp/adrecon_output

  # Generate Excel report from existing CSV files (standalone mode)
  pyadrecon.py --generate-excel-from /path/to/CSV-Files -o report.xlsx

>[!TIP]
>PyADRecon always tries LDAPS on TCP/636 first.
>
>If flag `--ssl` is not used, LDAP on TCP/389 may be tried as fallback.

>[!WARNING]
>If LDAP channel binding is enabled, this script will fail with `automatic bind not successful - strongerAuthRequired`, as ldap3 does not support it (see [here](https://github.com/cannatag/ldap3/issues/1049#issuecomment-1222826803)). You must use Kerberos authentication instead.
>
>If you use Kerberos auth under Linux, please create a valid `/etc/krb5.conf` and DC hostname entry in `/etc/hosts`. May read [this](https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=32628#KerberosClientConfiguration-*NIX/etc/krb5.confConfiguration). If you are on Windows, please make sure you have valid Kerberos tickets. May read [this](https://github.com/l4rm4nd/PyADRecon/tree/main/windows#kerberos-authentication). Note that you can provide an already existing TGT ticket to the script via `--tgt-file` or `--tgt-base64`. For example, obtained by Netexec via `netexec smb <TARGET> <ARGS> --generate-tgt <FILEMAME>`.

## Docker

There is also a Docker image available on GHCR.IO.

````
docker run --rm -v /etc/krb5.conf:/etc/krb5.conf:ro -v /etc/hosts:/etc/hosts:ro -v ./:/tmp/pyadrecon_output ghcr.io/l4rm4nd/pyadrecon:latest -dc dc01.domain.local -u admin -p password123 -d DOMAIN.LOCAL -o /tmp/pyadrecon_output
````
