I created this machine to help others learn some basic CTF hacking strategies and some tools. I aimed this machine to be very similar in difficulty to those I was breaking on the OSCP.

This is a boot-to-root machine will not require any guest interaction.

There are two designed methods for privilege escalation.

  • 23/09/2015 == v1.0.1
  • 22/09/2015 == v1.0

If you are having issues with VirtualBox, try the following:

  • Downloaded LordOfTheRoot_1.0.1.ova (confirmed file hash)
  • Downloaded and installed VMWare ovftool.
  • Converted the OVA to OVF using ovftool.
  • Modified the OVF using text editor, and did the following:

    replaced all references to "ElementName" with "Caption" replaced the single reference to "vmware.sata.ahci" with "AHCI"

  • Saved the OVF. +Deleted the .mf (Manifest) file. If you don't you get an error when importing, saying the SHA doesn't match for the OVF (I also tried modifying the hash, but no luck).

  • Try import the OVF file, and it should work fine.

The Challenge:

You are looking for two flags. Using discovered pointers in various elements of the running web application you can deduce the first flag (a downloadable file) which is required to find the second flag (a text file). Look, read and maybe even listen. You will need to use basic web application recon skills as well as some forensics to find both flags.

Level: Intermediate


The virtual machine comes in an OVA format, and is a generic 32 bit CentOS Linux build with a single available service (HTTP) where the challenge resides. Feel free to enable bridged networking to have the VM automatically be assigned a DHCP address. This VM has been tested in VMware Workstation 12 Player (choose "Retry" if needed), and VirtualBox 4.3.

The named of the Virtual machine is "Acid-Reloaded". This Virtual Machine contains both network logics and web logics. I have added new concept here and let's see how many of you think more logically. :-)

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 user and capture the flag. Once any one able to beat the box then shoot me a mail

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.

Source: http://owasp.com/index.php/OWASP_Broken_Web_Applications_Project

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.
