Your challenge, should you choose to accept, is to gain root access on the server! The employees over at Flick Inc. have been hard at work prepping the release of their server checker app. Amidst all the chaos, they finally have a version ready for testing before it goes live.

You have been given a pre-production build of the Android .apk that will soon appear on the Play Store, together with a VM sample of the server that they want to deploy to their cloud hosting provider.

The .apk may be installed on a phone (though I wont be offended if you don't trust me ;]) or run in an android emulator such as the Android Studio (https://developer.android.com/sdk/index.html).

Good Luck!

Note: Vmware will complain about the OVF specification. Just click retry on the import and everything should be ok!


@barrebas for testing and patience
@s4gi_ for testing and the inspiration

Welcome to the world of Acid.

Fairy tails uses secret keys to open the magical doors.


The named of the Virtual machine is "Acid Server". This Virtual Machine is completely web based. I have added little new concept here and hope people will enjoy solving this.You need to extract the rar and run the vmx using VMplayer . The machine has DHCP active list so once automatically assign an IP network, the next step will be to identify the target and discover the / the service / s to start the game.


Escalate the privileges to root and capture the flag. Once anyone able to beat the machine then please let me know.

The Broken Web Applications (BWA) Project produces a Virtual Machine running a variety of applications with known vulnerabilities for those interested in:

  • learning about web application security
  • testing manual assessment techniques
  • testing automated tools
  • testing source code analysis tools
  • observing web attacks
  • testing WAFs and similar code technologies

all the while saving people interested in doing either learning or testing the pain of having to compile, configure, and catalog all of the things normally involved in doing this process from scratch.

Release notes for the Open Web Application Security Project (OWASP) Broken Web Applications Project, a collection of vulnerable web applications that is distributed on a Virtual Machine in VMware format compatible with their no-cost and commercial VMware products.

More information about the project can be found at http://www.owaspbwa.org/.

The VM can be downloaded as a .zip file or as a much smaller .7z 7-zip Archive. BOTH FILES CONTAIN THE EXACT SAME VM! We recommend that you download the .7z archive if possible to save bandwidth (and time). 7-zip is available for Windows, Mac, Linux, and other Operating Systems.

!!! This VM has many serious security issues. We strongly recommend that you run it only on the "host only" or "NAT" network in the virtual machine settings !!!

By using this virtual machine, you agree that in no event will I be liable for any loss or damage including without limitation, indirect or consequential loss or damage, or any loss or damage whatsoever arising from loss of data or profits arising out of or in connection with the use of this software.

TL;DR: If something bad happens, it's not my fault.


Brainpan 3 has been tested and found to work with VMware Player, VMware Fusion, and Virtual Box.

Check to make sure Brainpan_III.ova has following checksums so you know your download is intact:

MD5 : 170e0d8b26ab721587537fcde69087a0

SHA1: ed9ae53c556a1ce6988b3a54621dd6469c8b8aa5

Import Brainpan_III.ova into your preferred hypervisor and configure the network settings to your needs. It will get an IP address via DHCP, but it's recommended you run it within a NAT or visible to the host OS only since it is vulnerable to attacks.


Get root and get the flag.

Our resident ROP ninja barrebas recently gave the team a bootcamp on Return Oriented Programming. The presentation was followed by a demo walkthrough on writing a ROP exploit on a vulnerable application. Since the presentation was well received, he’s decided to make the slides available to everyone. You can view them at https://speakerdeck.com/barrebas/rop-primer.

We hope you enjoy it!

ROP Primer

This VM is meant as a small introduction to 32-bit return-oriented-programming on Linux. It contains three vulnerable binaries, that must be exploited using ROP.

The machine is built and tested in VirtualBox 4.3.20. It's an Ubuntu 32 bit VM, with ASLR disabled. Useful tools like gdb-peda are installed. A description of the levels, including instructions, can be found on the webserver.

A big shout-out to my team mates of the Vulnhub CTF Team!

Darknet has a bit of everything, a sauce with a touch of makeup and frustration that I hope will lead hours of fun for migraines and who dares to conquer his chambers.

As the target gets used will read the file contents /root/flag.txt obviously once climbed the privileges necessary to accomplish the task.

The image can be mounted with VirtualBox . The machine has DHCP active list so once automatically assign an IP network, the next step will be to identify the target and discover the / the service / s to start the game. Good luck !. If you want to send in pdf format solucionarios can do so at the following address: s3csignal [at] gmail [dot] com

This exercise covers the exploitation of a session injection in the Play framework. This issue can be used to tamper with the content of the session while bypassing the signing mechanism

New VM challenge that should be fun for people trying to get into packet analysis!

There are several steps to this box. I created it with virtualbox. The VM is built on:

Ubuntu 14.04 32 bit

If you beat the box then please shoot me an email! Have fun guys!

P.S. I got the word "Fart Knocker" from watching beavis and butthead back in the day. Otherwise you kids might not understand :)

ZORZ is another VM that will challenge your webapp skills. There are 3 separate challenges (web pages) on this machine. It should be pretty straight forward. I have explained as much as I can in the readme file:

Welcome to the ZorZ VM Challenge

This machine will probably test your web app skills once again. There are 3 different pages that should be focused on (you will see!) If you solve one or all three pages, please send me an email and quick write up on how you solved each challenge. Your goal is to successfully upload a webshell or malicious file to the server. If you can execute system commands on this box, thats good enough!!! I hope you have fun!
