Steps of where to go first in this repo:

1️⃣ Read the PDF guide: Responding To Responder - PDF Guide

2️⃣ Access the exported JSON Intune Configuration Policies:

- 📄 Disable LLMNR Intune - Intune JSON File
- Brief Explanation: This will disable Local-Link Multicast Name Resolution (LLMNR) in the en, by enabling: Turn off multicast name resolution and Turn off smart multi homed name resolution.
See more details in PDF guide (Step 1).

- 📄 LLMNR, NetBIOS, mDNS, WPAD, LM, NTLM Security - Intune JSON File
- 📄 Network Auth Security - Intune JSON File
- 📄 Password and Credential Hash Security - Intune JSON File
- Brief Explanation: These three are respecting additional measures to lock down further what each protocol can do, as well as NTLM and LM credential network travel and hash storage security. See more details in PDF guide from page 13 (Step 1).

3️⃣ Access the exported PowerShell Platform scripts:
- 🪄 Disable mDNS - Platform Script
- Brief Explanation: This script will look to see if existing DWORD "EnableMDNS" is present and set to "0", if not create and/or update.

- 🪄 Disable NetBIOS - Platform Script
- Brief Explanation: This script will iterate over the listed NIC (Ensuring it applies change to all) checking if DWORD "NetbiosOptions" is present and set to "2", if not create and/or update. This will ensure each NIC has the NetBIOS setting: "Disable NetBIOS over TCP/IP" set.

- 🪄 Disable WPAD - Platform Script
- Brief Explanation: This script will look to see if existing DWORD "DisableWPAD" is present and set to "1", if not create and/or update.
