EDR Reverse Engineering Workspace

Universal workflow for complete reverse engineering of endpoint detection and response (EDR) products. Every EDR dropped into this workspace gets the same systematic treatment: full decompilation, rule extraction, ML model extraction, vulnerability analysis, detection gap analysis, and tradecraft development.

Standardized Folder Structure

When given a new EDR product, create this structure under <product>/:

<product>/

name

edr-reverse-engineering

description

Standardized workflow for reverse engineering endpoint security products, including extraction, decompilation, rule and model recovery, vulnerability analysis, detection gap analysis, proof-of-concept planning, live probes, and stakeholder reports. Use when Claude is asked to analyze an endpoint detection and response product, endpoint protection agent, security sensor, antivirus engine, or similar endpoint security package from installer artifacts, extracted binaries, live systems, or prior workspace outputs.

EDR Reverse Engineering

Use this skill to run a complete, repeatable reverse-engineering workflow for endpoint security products. Apply the same structure to every product so outputs can be compared across analyses and future work can resume without rediscovery.

Basic install of Bluetrait RMM software.

SDDL Security Testing and Demonstration Guide

1. Decode an SDDL String (Basic Permissions Breakdown)

Objective: Retrieve and interpret SDDL for a file.

Command:

(Get-Acl C:\Windows\System32\cmd.exe).Sddl

Expected Outcome:

Enable PowerShell Web Access like an APT

Ref: https://www.cisa.gov/news-events/cybersecurity-advisories/aa24-241a

PowerShell:

# PrivCheck
if (-NOT ([Security.Principal.WindowsPrincipal][Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole] "Administrator")) {
    Write-Warning "Please run this script as an Administrator!"
    Exit

Ivanti Virtual Traffic Manager (VTM) Docker Setup

This guide outlines the steps to set up the Ivanti Virtual Traffic Manager (VTM) using Docker.

Prerequisites

Before you begin, ensure you have the following:

A system with Docker installed.
Docker Hub credentials (if required).

	# Handala Threat Group - Atomic Red Team Chain Reaction
	# Run in order to simulate endpoint behaviors (initial access -> execution -> evasion -> discovery -> exfil -> impact).
	# Use with Invoke-AtomicRedTeam or Attack Range in a LAB only.
	#
	# Get Atomic Red Team:
	# git clone https://github.com/redcanaryco/atomic-red-team.git
	# Install-Module -Name Invoke-AtomicRedTeam -Scope CurrentUser
	#
	# Run full chain (PowerShell on Windows lab host):
	# Invoke-AtomicTest All -TestGuids (see test_guids below) -ShowDetailsBrief

	.SYNOPSIS

	A tool to perform rapid triage of decompressed application packages (.msix and .appx files).

	.DESCRIPTION

	Get-AppPackageTriageInfo parses key information from an uncompressed application package (.msix and .appx) without needing to first install it.
