ADRecon: Active Directory Recon Follow ADRecon on Twitter

ADRecon is a tool which extracts and combines various artefacts (as highlighted below) out of an AD environment. The information can be presented in a specially formatted Microsoft Excel report that includes summary views with metrics to facilitate analysis and provide a holistic picture of the current state of the target AD environment.

The tool is useful to various classes of security professionals like auditors, DFIR, students, administrators, etc. It can also be an invaluable post-exploitation tool for a penetration tester.

It can be run from any workstation that is connected to the environment, even hosts that are not domain members. Furthermore, the tool can be executed in the context of a non-privileged (i.e. standard domain user) account. Fine Grained Password Policy, LAPS and BitLocker may require Privileged user accounts. The tool will use Microsoft Remote Server Administration Tools (RSAT) if available, otherwise it will communicate with the Domain Controller using LDAP.

The following information is gathered by the tool:

  • Forest;
  • Domain;
  • Trusts;
  • Sites;
  • Subnets;
  • Default and Fine Grained Password Policy (if implemented);
  • Domain Controllers, SMB versions, whether SMB Signing is supported and FSMO roles;
  • Users and their attributes;
  • Service Principal Names (SPNs);
  • Groups and memberships;
  • Organizational Units (OUs);
  • GroupPolicy objects and gPLink details;
  • DNS Zones and Records;
  • Printers;
  • Computers and their attributes;
  • PasswordAttributes (Experimental);
  • LAPS passwords (if implemented);
  • BitLocker Recovery Keys (if implemented);
  • ACLs (DACLs and SACLs) for the Domain, OUs, Root Containers, GPO, Users, Computers and Groups objects;
  • GPOReport (requires RSAT);
  • Kerberoast (not included in the default collection method); and
  • Domain accounts used for service accounts (requires privileged account and not included in the default collection method).

ADRecon was presented at: Black Hat Arsenal Asia 2018 - Slidedeck

Black Hat Arsenal USA 2018 | DEFCON 26 Demolabs - Slidedeck

Getting Started

These instructions will get you a copy of the tool up and running on your local machine.


  • .NET Framework 3.0 or later (Windows 7 includes 3.0)
  • PowerShell 2.0 or later (Windows 7 includes 2.0)



If you have git installed, you can start by cloning the repository:

git clone

Otherwise, you can download a zip archive of the latest release. The intent is to always keep the master branch in a working state.



To run ADRecon on a domain member host.

PS C:\> .\ADRecon.ps1

To run ADRecon on a domain member host as a different user.

PS C:\>.\ADRecon.ps1 -DomainController <IP or FQDN> -Credential <domain\username>

To run ADRecon on a non-member host using LDAP.

PS C:\>.\ADRecon.ps1 -Protocol LDAP -DomainController <IP or FQDN> -Credential <domain\username>

To run ADRecon with specific modules on a non-member host with RSAT. (Default OutputType is STDOUT with -Collect parameter)

PS C:\>.\ADRecon.ps1 -Protocol ADWS -DomainController <IP or FQDN> -Credential <domain\username> -Collect Domain, DomainControllers

To generate the ADRecon-Report.xlsx based on ADRecon output (CSV Files).

PS C:\>.\ADRecon.ps1 -GenExcel C:\ADRecon-Report-<timestamp>

When you run ADRecon, a ADRecon-Report-<timestamp> folder will be created which will contain ADRecon-Report.xlsx and CSV-Folder with the raw files.

Future Plans

  • Replace System.DirectoryServices.DirectorySearch with System.DirectoryServices.Protocols and add support for LDAP STARTTLS and LDAPS (TCP port 636).
  • Add Domain Trust Enumeration.
  • Add option to filter default ACLs.
  • Gather ACLs for other objects such as Users, Group, etc.
  • Additional export and storage option: export to STDOUT, SQLite, xml, json, html, pdf.
  • Use the EPPlus library for Excel Report generation and remove the dependency on MS Excel.
  • List issues identified and provide recommended remediation advice based on analysis of the data.
  • Add PowerShell Core support.
