PowerTools - Collection Of PowerShell Projects With A Focus On Offensive Operations

Veil's PowerTools are a collection of PowerShell projects with a focus on offensive operations.

This collection contains five projects:
  • PowerUp
  • PowerBreach
  • PowerPick
  • PewPewPew
  • PowerView


PowerUp is a powershell tool to assist with local privilege escalation on Windows systems. It contains several methods to identify and abuse vulnerable services, as well as DLL hijacking opportunities, vulnerable registry settings, vulnerable schtasks, and more.

Service Enumeration:

Get-ServiceUnquoted             -   returns services with unquoted paths that also have a space in the name
Get-ServiceFilePermission       -   returns services where the current user can write to the service binary path or its config
Get-ServicePermission           -   returns services the current user can modify

Service Abuse:

Invoke-ServiceUserAdd           -   modifies a modifiable service to create a user and add it to the local administrators
Invoke-ServiceCMD               -   execute an arbitrary command through service abuse
Write-UserAddServiceBinary      -   writes out a patched C# service binary that adds a local administrative user
Write-CMDServiceBinary          -   writes out a patched C# binary that executes a custom command
Write-ServiceEXE                -   replaces a service binary with one that adds a local administrator user
Write-ServiceEXECMD             -   replaces a service binary with one that executes a custom command
Restore-ServiceEXE              -   restores a replaced service binary with the original executable
Invoke-ServiceStart             -   starts a given service
Invoke-ServiceStop              -   stops a given service
Invoke-ServiceEnable            -   enables a given service
Invoke-ServiceDisable           -   disables a given service
Get-ServiceDetail               -   returns detailed information about a service

Get-RegAutoLogon                -   checks for Autologon credentials in the registry
Get-VulnAutoRun                 -   checks for any modifiable binaries/scripts (or their configs) in HKLM autoruns


Get-VulnSchTask                 -   find schtasks with modifiable target files
Get-UnattendedInstallFile       -   finds remaining unattended installation files
Get-Webconfig                   -   checks for any encrypted web.config strings

Write-UserAddMSI                -   write out a MSI installer that prompts for a user to be added
Invoke-AllChecks                -   runs all current escalation checks and returns a report


PowerBreach is a backdoor toolkit that aims to provide the user a wide variety of methods to backdoor a system. It focuses on diversifying the "trigger" methods which allows the user flexibility on how to signal to the backdoor that it needs to phone home. PowerBreach focuses on memory only methods that do not persist across a reboot without further assistance and is not a silver bullet when it comes to cover communications.

Helper Functions:

Add-PSFirewallRules - Adds powershell to the firewall on 65K ports. Required Admin
Invoke-CallbackIEX - The location for the various callback mechanisms. Calls back and executes encoded payload.

Backdoors Available:

Invoke-EventLogBackdoor: Monitors for failed RDP login attempts. Admin-Yes, Firewall-No, Auditing Reqd
Invoke-PortBindBackdoor: Binds to TCP Port. Admin-No, Firewall-Yes
Invoke-ResolverBackdoor: Resolves name to decide when to callback. Admin-No, Firewall-No
Invoke-PortKnockBackdoor: Starts sniffer looking for trigger. Admin-Yes, Firewall-Yes
Invoke-LoopBackdoor: Callsback on set interval. Admin-No, Firewall-No
Invoke-DeadUserBackdoor: Looks for "dead" user and calls back when does not exist. Admin-No, Firewall-No

Callback URIs Available:

http://<host:port/resource> - Perform standard http callback
https://<host:port/resource> - Perform standard https callback
dnstxt://<host> - Resolve DNS text record for host which is the payload


This project focuses on allowing the execution of Powershell functionality without the use of Powershell.exe. Primarily this project uses.NET assemblies/libraries to start execution of the Powershell scripts.

Many thanks to those in the offensive powershell community. This work is not ground breaking but hopefully will motivate offense and defense to understand the implications and lack of protections available.


This project provides a powershell scipt (psinject.ps1) which implements the Invoke-PSInject function. This script is based off Powersploit's Invoke-ReflectivePEInjection and reflectively injects the ReflectivePick DLL. It allows for the replacement of the callback URL that is hard coded into the DLL. See this script for more details.

The script that it calls back for must be base64 encoded. To do this, you can simply use the built in linux utility 'base64'.

import-module psinject.ps1
Invoke-PSInject -Verbose -ProcID 0000 -CBURL


This project is a reflective DLL based on Stephen Fewer's method. It imports/runs a .NET assembly into its memory space that supports the running of Powershell code using System.Management.Automation. Due to its' reflective property, it can be injected into any process using a reflective injector and allows the execution of Powershell code by any process, not just Powershell.exe. It extends inject/migrate capabilities into powershell.

This DLL is meant to be used with PSInject.ps1 which provide the ability to modify the hardcoded callback URL or with Metasploit after compiling or patching the URL manually.


This project is a .NET executable which allows execution of Powershell code through a number of methods. The script can be embedded as a resource, read from a url, appeneded to the binary, or read from a file. It was originally used as a proof of concept to demonstrate/test the blocking of powershell and bypass of applocker.

Man Page
sharppick.exe [<flag> <argument>]
-f <file> : Read script from specified file
-r <resource name> : Read script from specified resource
-d <url> : Read script from URL
-a <delimeter> : Read script appended to current binary after specified delimeter. Delimeter should be very very unique string

This repo contains scripts that utilize a common pattern to host a script on a PowerShell webserver, invoke the IEX download cradle to download/execute the target code and post the results back to the server, and then post-process any results.

PowerView is a PowerShell tool to gain network situational awareness on Windows domains. It contains a set of pure-PowerShell replacements for various windows "net *" commands, which utilize PowerShell AD hooks and underlying Win32 API functions to perform useful Windows domain functionality.

It also impements various useful metafunctions, including some custom-written user-hunting functions which will identify where on the network specific users are logged into. It can also check which machines on the domain the current user has local administrator access on. Several functions for the enumeration and abuse of domain trusts also exist. See function descriptions for appropriate usage and available options.

To run on a machine, start PowerShell with "powershell -exec bypass" and then load the PowerView module with: PS> Import-Module .\powerview.psm1 or load the PowerView script by itself: PS> Import-Module .\powerview.ps1

For detailed output of underlying functionality, pass the -Debug flag to most functions.

For functions that enumerate multiple machines, pass the -Verbose flag to get a progress status as each host is enumerated. Most of the "meta" functions accept an array of hosts from the pipeline.
