This is a writeup about a vulnhub machine InfoSec Prep This box is an really easy box in order to make a small selection for entering a give away for a 30d voucher to the OSCP Lab, Lab materials, and an exam attempt. The box was created by FalconSpy and publish on July 11 2020. It involves a robots.txt file, some base64 an SSH key, lxd and a SUID binary.

After the bulldog machine I worked on the born2root one. A simple boot2root machine by Hadi Mene.

At the moment I have some times to work again on Vulnhub virtual machine. So here I picked the first one at the moment: Bulldog: 1 A simple boot2root machine by Nick Frichette.

As droopy was not really hard and doesn't contain as much web vulnerability as I would hope for, I tried an other VM SecTalks: BNE0x03 - Simple There were also hints on the description of the machine but with my resolution they do not appear when just browsing the main page of vulnhub so I have not spoiled myself with the hints this time.

A few days ago, I installed a new pentesting box based on Arch Linux with Kali

in a virtual machine. In order to test it I select a light vulnbox on vulnhub : Droopy. There were two hints on the description of the machine on the vulnhub download page:

1. Grab a copy of the rockyou wordlist.
2. It's fun to read other people's email.

We will see how to use them in a moment :)

Still playing with the vulnhub machines this time it is the turn of FlickII. This one is different from the others as it has an android application associated. It would be a great exercice to play with mobile application, decompile it and see what is in the inside.

After the Acid challenge I was really motivated. Therefore I give a look at another vulnhub machine I had already download since a while: NullByte.

Since Fart knocker in June I have worked on an other vulnhub machine: darknet. But this one is really hard and get me stuck. I was a bit demotivated to continue vulnhub's machines but I got some time this week, therefore I tried the Acid one.

I continued to play with the vulnhub virtual machine an started the TopHatSec - Fart Knocker. This VM is an Ubuntu 14.04 32 bits.

The goal of this challenge is to break into the machine and root it.

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 :)

I continued to play with the vulnhub virtual machine and started the TopHatSec - Freshly.

"The goal of this challenge is to break into the machine via the web and find the secret hidden in a sensitive file. If you can find the secret, send me an email for verification. :)"
