jivoi / windows_hardening.cmd
Created November 21, 2022 09:03 — forked from mackwage/windows_hardening.cmd
Script to perform some hardening of Windows OS
:: Windows 10 Hardening Script
:: This is based mostly on my own personal research and testing. My objective is to secure/harden Windows 10 as much as possible while not impacting usability at all. (Think being able to run on this computer's of family members so secure them but not increase the chances of them having to call you to troubleshoot something related to it later on). References for virtually all settings can be found at the bottom. Just before the references section, you will always find several security settings commented out as they could lead to compatibility issues in common consumer setups but they're worth considering.
:: Obligatory 'views are my own'. :)
:: Thank you @jaredhaight for the Win Firewall config recommendations!
:: Thank you @ricardojba for the DLL Safe Order Search reg key!
:: Thank you @jessicaknotts for the help on testing Exploit Guard configs and checking privacy settings!
:: Best script I've found for Debloating Windows 10: https://github.com/Sycnex/Windows10Debloater

WMIC Service Modification for Lateral Movement
As always, only for use on networks you own or have permission to test against.
Similar functionality to SpiderLabs SCShell (https://github.com/SpiderLabs/SCShell) but from the command line using WMIC to run commands on other systems remotely.
If attempting to run multiple commands, SCShell will probably be move convenient as it automates the below steps. However, for one-offs this works fine as well.
The process involves a total of four commands, three of which can be combined on the command line to form one large block.
Step 1: Get the current pathName of your target service so we can restore it once we've ran our command (in our case XblAuthManager)
wmic /user:DOMAIN\USERNAME /password:PASSWORD /node:TARGET_IP service where name='XblAuthManager' get pathName
Assuming you have a mimikatz dump named "mimikatz_dump.txt", I made these bash one-liners that will reformat the mimikatz output to "domain\user:password"
First, before using these parsers, run: "dos2unix mimikatz_dump.txt"
Mimikatz 1.0:
cat mimikatz_dump.txt | grep -P '((Utilisateur principal)|(msv1_0)|(kerberos)|(ssp)|(wdigest)|(tspkg))\s+:\s+.+' | grep -v 'n\.' | sed -e 's/^\s\+[^:]*:\s\+//' | sed -e 's/Utilisateur principal\s\+:\s\+\(.*\)$/\n\1/' | sort -u
Mimikatz 2.0 (unfortunately, you must "apt-get install pcregrep" because reasons):

Pwning internal networks automagically

Intro

This document pools several awesome tools and blog entries together (see "Resources" at the end of this doc) in an attempt to automate the process of getting an initial foothold on a network in a situation where you have no valid credentials.

Download and install ntlmrelay

Ok, so one weird thing I'm trying to figure out is if I install ntlmrelay as the first tool we'll use, these steps seem to work ok:

git clone https://github.com/CoreSecurity/impacket.git /opt/impacket
cd /opt/impacket
pip install .
