This is a boot2root VM and is a continuation of the Basic Pentesting series. This series is designed to help newcomers to penetration testing develop pentesting skills and have fun exploring part of the offensive side of security.

VirtualBox is the recommended platform for this challenge (though it should also work with VMware -- however, I haven’t tested that).

This VM is a moderate step up in difficulty from the first entry in this series. If you’ve solved the first entry and have tried a few other beginner-oriented challenges, this VM should be a good next step. Once again, this challenge contains multiple initial exploitation vectors and privilege escalation vulnerabilities.

Your goal is to remotely attack the VM, gain root privileges, and read the flag located at /root/flag.txt. Once you’ve finished, try to find other vectors you might have missed! If you’d like to send me a link to your writeup, enjoyed the VM or have questions or feedback, feel free to contact me at: [email protected]

If you finished the VM, please also consider posting a writeup! Writeups help you internalize what you worked on and help anyone else who might be struggling or wants to see someone else’s process. There were lots of wonderful writeups for Basic Pentesting: 1, and I look forward to reading the writeups for this challenge.

I recently got done creating an OSCP type vulnerable machine that's themed after the great James Bond film (and even better n64 game) GoldenEye. The goal is to get root and capture the secret GoldenEye codes - flag.txt.

I'd rate it as Intermediate, it has a good variety of techniques needed to get root - no exploit development/buffer overflows. After completing the OSCP I think this would be a great one to practice on, plus there's a hint of CTF flavor.

I've created and validated on VMware and VirtualBox. You won't need any extra tools other than what's on Kali by default. Will need to be setup as Host-Only, and on VMware you may need to click "retry" if prompted, upon initially starting it up because of formatting.

A new OSCP style lab involving 2 vulnerable machines, themed after the cyberpunk classic Neuromancer - a must read for any cyber-security enthusiast. This lab makes use of pivoting and post exploitation, which I've found other OSCP prep labs seem to lack. The goal is the get root on both machines. All you need is default Kali Linux.

I'd rate this as Intermediate. No buffer overflows or exploit development - any necessary password cracking can be done with small wordlists. It's much more related to an OSCP box vs a CTF. I've tested it quite a bit, but if you see any issues or need a nudge PM me here.

Virtual Box Lab setup instructions are included in the zip download, but here's a quick brief:

Straylight - simulates a public facing server with 2 NICS. Cap this first, then pivot to the final machine. Neuromancer - is within a non-public network with 1 NIC. Your Kali box should ONLY be on the same virtual network as Straylight.

=========

This Virtual machine is using ubuntu (32 bit)

Other packages used: -

PHP Apache MySQL Apache tomcat

This virtual machine is having intermediate to medium difficulty level. One need to break into VM using web application and from there escalate privileges to gain root access. Gaining low or root privilege shell can be done in two ways (for both)

Series: Gemini Inc

Description: I have decided to create vulnerable machines that replicate the vulnerabilities and difficulties I’ve personally encountered during my last year (2017) of penetration testing.

Some of the vulnerabilities require the “Think out of the box (fun)” mentality and some are just plain annoyance difficulties that require some form of automation to ease the testing.

GeminiInc v2 has been created that replicate a few issues that I’ve encountered which was really interesting and fun to tackle, I hope it will be fun for you guys as well.

Adding a little made-up background story to make it more interesting…

Introduction: Gemini Inc has contacted you to perform a penetration testing on one of their internal system. This system has a web application that is meant for employees to export their profile to a PDF. Identify any vulnerabilities possible with the goal of complete system compromise with root privilege. To demonstrate the level of access obtained, please provide the content of flag.txt located in the root directory as proof.

  • File size: 2239959453
  • SHA 1: 5f210dd9a52a701bab262a9def88009b1ca46300

Virtual Machine:

  • Format: Virtual Machine (VMWare)
  • Operating System: Debian

Networking:

  • DHCP Service : Enabled
  • IP Address: Automatically Assigned

More information can be obtained from my blog post on this vulnerable machine: https://scriptkidd1e.wordpress.com/

Intended solution will be provided some time after this has been published: https://scriptkidd1e.wordpress.com/geminiinc-v2-virtual-machine-walkthrough/

The VM has been tested on the following platform and is working:

  • Mac OSX VMWare Fusion
  • Windows 10 VMWare Player
  • Windows 10 VMWare Workstation

It should work with any virtual machine player as well. It will be able to obtain an I.P Address with DHCP so no additional configuration is required. Simply import the downloaded VM and you are good to go.
