VulnHub Machines Walkthrough Series: Brainpan – Part 1

Continuing with our series on testing vulnerable virtual machines, in this article we will see a walkthrough of an interesting VulnHub machine called Brainpan. This is Part 1 of this article, where we will look into the getting the user-level reverse shell.

Note: For all these machines, I have used VMware Workstation to provision VMs. Kali Linux VM will be my attacking box. Also, the techniques used are solely for educational purposes. I am not responsible if the listed techniques are used against any other targets.

VM Details – From the Author

  • 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.
