About:
Pandora's box is a Boot2Root VM focused on binary exploitation and 
reverse engineering. You have to complete all levels to r00t the box. 
Some levels come with a readme file which you should read.

Usage:
Import, boot and wait 60 seconds for everything to start up before 
scanning it.

Shootout:
Major thanks to Barrebas and Jelle for testing the VM and challenges 
and the feedback.

  • Objective: gain shell access and root the box.
  • Hardness: intermediate-> advanced.
  • Note: The box doesn't respond to ping, so be sure to check the DHCP lease.

Welcome to my first boot2root VM! Inspired by various CTF events I took part in and by couple cool concepts I learnt in the last couple months.

Rules of engagement are simple - find a way in, escalate your privileges all the way up to the root and get the flag!

As with all VMs like this, think outside the box, don't jump to conclusions too early and "read between the lines" :)

The VM has been tested on VMWare and VirtualBox, just import it, ensure the network is set as "Host Only" and run it. It should pick up the IP address automatically.

Enjoy! :)

Underc0de Weekend is a weekly challenge we (underc0de) are doing. The goal is to be the first to resolve it, to earn points and prizes (http://underc0de.org/underweekend.php).

Enjoy

Tr0ll: 2

Maleus 24 Oct 2014

The next machine in the Tr0ll series of VMs. This one is a step up in difficulty from the original Tr0ll but the time required to solve is approximately the same, and make no mistake, trolls are still present! :)

Difficulty is beginner++ to intermediate.

The VM should pull a valid IP from DHCP. This VM has been verified to work on VMware workstation 5, VMware player 5, VMware Fusion, and Virtual box. Virtual box users may need to enable the additional network card for it to pull a valid IP address.

Special thanks to @Eagle11, @superkojiman and @leonjza for suffering through the testing and the members of #overflowsec on freenode for giving me ideas.

If you have issues with the machine, feel free to contact me at @Maleus21 or maleus overflowsecurity.com.

Notes to the Player


As part of the challenge, Kvasir utilises LXC to provide kernel isolation. When the host VM boots, it takes can take a little bit of time before the containers become available.

It is therefore advised to wait 30-60 seconds after the login prompt is presented, before attacking the VM.

A few other pointers:

  • Not every LXC is ‘rootable’
  • No SSH brute-forcing is required

Pretty much thought of a pretty neat idea I hadn't seen done before with a VM, and I wanted to turn it into reality!

Your job is to escalate to root, and find the flag.

Since I've gotten a few PM's, remember: There is a difference between "Port Unreachable" and "Host Unreachable". DHCP is not broken ;)

Gotta give a huge shoutout to c0ne for helping to creating the binary challenge, and rasta_mouse and recrudesce for testing :)

Also, gotta thank barrebas who was able to find a way to make things easier... but of course that is fixed with this update! ;)

TL;DR - You are about to load up a virtual machine with vulnerabilities created by hackers. If something bad happens, it's not our fault.

ABOUT

Persistence aims to provide you with challenging obstacles that block your path to victory. It is perhaps best described by quotes made by some famous people:

"A little more persistence, a little more effort, and what seemed hopeless failure may turn to glorious success." - Calvin Coolidge

"Energy and persistence conquer all things." - Benjamin Franklin

"Persistence and resilience only come from having been given the chance to work though difficult problems." - Gever Tulley

GOAL

Get a root shell and read the contents of /root/flag.txt to complete the challenge!

SETUP

The virtual machine will get an IP address via DHCP, and it has been tested on the following hypervisors:

VMware Fusion 6 VMware Player 6 VMware Workstation 10 VirtualBox 4.3

SHOUT OUTS
