A new machine works in VirtualBox. Two flags: user and root. Some easy overflow stuff.

This is the evil twin of JOY. Unlike JOY, this machine is designed to drive you crazy. Stephen Hawking once mentioned, "God plays dice and throws them into places where they cannot be seen."

The dice for the machine can all be found on the Internet. Like all other machines built by me, you should not torment yourself by brute force. But perhaps, JOY and TORMENT are two sides of the same coin of satisfaction? Can we really spark joy if we can't first be tormented to endure sufferance?

This machine guarantees to teach you some new ways of looking at enumeration and exploitation. Unlike all the other OSCP-like machines written by me, this machine will be mind-twisting and maybe mind-blowing. You may lose your mind while at it, but we will still nudge you to... try harder!

This is NOT an easy machine and you should not feel discouraged if you spend a few days headbanging on this machine. At least three competent pentesters I have asked to test this machine report days (thankfully not weeks) of head banging and nerve wrecking. Do this machine if you enjoy being humbled.

If you MUST have hints for this machine (even though they will probably not help you very much until you root the box!): Torment is (#1): what happens when you can't find your answer on Google, even though it's there, (#2): what happens when you plead for mercy, but do not succeed, (#3): https://www.youtube.com/watch?v=7ge1yWot4cE

Does penetration testing spark joy? If it does, this machine is for you.

This machine is full of services, full of fun, but how many ways are there to align the stars? Perhaps, just like the child in all of us, we may find joy in a playground such as this.

This is somewhat OSCP-like for learning value, but is nowhere as easy to complete with an OSCP exam timeframe. But if you found this box because of preparation for the OSCP, you might as well try harder. :-)

If you MUST have hints for this machine (even though they will probably not help you very much until you root the box!): Joy is (#1): https://www.youtube.com/watch?v=9AvWs2X-bEA, (#2): something that should be replicated, (#3): what happens when you clean out seemingly "hidden" closets.

Note: There are at least two reliable ways of obtaining user privileges and rooting this machine. Have fun. :-)

Description: unknowndevice64 v2.0 is a beginner level boot2root challenge. The OVA has been tested on both VMware (with some fix provided in this video https://www.youtube.com/watch?v=scRpxo8fra4) and Virtual Box.

Difficulty: Beginner

Flags: Your Goal is to get root and read flag.txt with at least two different ways.

Networking: - DHCP: Enabled - IP Address: Automatically assigned

Hint: Follow your intuitions ... and enumerate! and for any questions, feel free to contact me on Twitter: @unknowndevice64

Happy Hacking..!!!

HackinOS is a beginner level CTF style vulnerable machine. I created this VM for my university’s cyber security community and all cyber security enthusiasts. I thank to Mehmet Oguz Tozkoparan, Ömer Faruk Senyayla and Tufan Gungor for their help during creating this lab.

NOTE: localhost is meant to be there!

DC: 1

DCAU 28 Feb 2019

Description

DC-1 is a purposely built vulnerable lab for the purpose of gaining experience in the world of penetration testing.

It was designed to be a challenge for beginners, but just how easy it is will depend on your skills and knowledge, and your ability to learn.

To successfully complete this challenge, you will require Linux skills, familiarity with the Linux command line and experience with basic penetration testing tools, such as the tools that can be found on Kali Linux, or Parrot Security OS.

There are multiple ways of gaining root, however, I have included some flags which contain clues for beginners.

There are five flags in total, but the ultimate goal is to find and read the flag in root's home directory. You don't even need to be root to do this, however, you will require root privileges.

Depending on your skill level, you may be able to skip finding most of these flags and go straight for root.

Beginners may encounter challenges that they have never come across previously, but a Google search should be all that is required to obtain the information required to complete this challenge.


Technical Information

DC-1 is a VirtualBox VM built on Debian 32 bit, so there should be no issues running it on most PCs.

While I haven't tested it within a VMware environment, it should also work.

It is currently configured for Bridged Networking, however, this can be changed to suit your requirements. Networking is configured for DHCP.

Installation is simple - download it, unzip it, and then import it into VirtualBox and away you go.


Important

While there should be no problems using this VM, by downloading it, you accept full responsibility for any unintentional damage that this VM may cause.

In saying that, there shouldn't be any problems, but I feel the need to throw this out there just in case.


Contact

This is the first vulnerable lab challenge that I've created, so feel free to let me know what you think of it.

I can be contacted via Twitter - @DCAU7

N/A

A series of challenges to test basic stack overflow skills, originally developed for the Sheffield University Ethical Hacking Society.

Starting as level0 exploit a binary owned by the next user to get the flag.

There are 5 flags to collect:

  • /home/level1/level1.txt
  • /home/level2/level2.txt
  • /home/level3/level3.txt
  • /home/level4/level4.txt
  • /root/root.txt

Each flag is the corresponding users password, so once you exploit the binary owned by level1 and get the level1 flag, you can su to level1 and take on the next challenge

To start boot the machine and login as:

  • username: level0
  • password: level0

You'll find the first binary to exploit is: /home/level0/level1

You may want to increase the resources allocated to the machine
