2. Extract the downloaded zip file
3. Open a PowerShell prompt to the location of the extracted file and run Import-Module .\Locksmith.psd1

Script

Download the standalone script (classic) without module:

1. Download the latest script version: https://github.com/TrimarcJake/Locksmith/releases/latest/download/Invoke-Locksmith.zip
2. Open a PowerShell prompt to the location of the downloaded file and run .\Invoke-Locksmith.ps1

Run Locksmith

Mode 0: Identify Issues, Output to Console (Default)

Scans:  Select Which Scans to Run

Use the -Scans parameter to choose which vulnerabilities to scan for. Acceptable values include All, Auditing, ESC1, ESC2, ESC3, ESC4, ESC5, ESC6, ESC8, or PromptMe. The PromptMe option presents an interactive list allowing you to select scans.

# Run all scans
Invoke-Locksmith -Scan All

# Prompt the user for a list of scans to select
Invoke-Locksmith.ps1 -Scans PromptMe

# Scan for ESC1 vulnerable paths
Invoke-Locksmith.ps1 -Scans ESC1

# Scan for ESC1, ESC2, and ESC8 vulnerable paths
Invoke-Locksmith.ps1 -Scans ESC1,ESC2,ESC8
