• Reverse engineering hashed data

Getting Started

VM Setup - VirtualBox Network Configuration

We recommend setting up a VirtualBox Host-Only network.

• Select "Host-Only Network" in VirtualBox network settings.
• This configuration provides a private network between the host and the VM.

If there is no Host-Only Network configured:

• Go to "Tools" in VirtualBox and click on "Network".
• Select "Host-Only Network" and create a new one if none exists.
• Open the Networking section for your virtual machine and select "Host-only Network".
• Choose the host-only network from the drop-down list, preferably the one you just created.

SSH Access

To access the VM via SSH

ssh -p 4242 levelXX@<ip>
