How to Build a Cuckoo Sandbox Malware Analysis System

I had a heck of a time getting a Cuckoo sandbox running, and below I hope to help you get one up and running relatively quickly by detailing out the steps and gotchas I stumbled across along the way. I mention this in the references at the end of this gist, but what you see here is heavily influenced by this article from Nviso

Build your Linux Cuckoo VM

Setup a Ubuntu 16.04 64-bit desktop VM (download here) in VMWare with the following properties:

100GB hard drive
2 procs
8 gigs of RAM

	# Conversion of http://docs.splunk.com/Documentation/Splunk/latest/RESTAPI/RESTsearch#search.2Fjobs.2Fexport
	# example using curl, to PowerShell with Invoke-RestMethod cmdlet
	#
	# $ curl -k -u admin:changeme https://localhost:8089/services/search/jobs/export
	# --data-urlencode search="search index=_internal \| stats count by sourcetype"
	# -d output_mode=json -d earliest="rt-5m" -d latest="rt"

	$cred = Get-Credential

	# This will allow for self-signed SSL certs to work

	:: 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.
