Installing REMnux 6

Installing REMnux 6 is easy if you already have Oracle VirtualBox on your system.

Since I already had VirtualBox up and running, it took less than 10 minutes to download the REMnux 6 virtual appliance file and then import it into Virtualbox.

I opted for the default settings and had REMnux 6 running in no time.

If you have an issue with the window/screen size, install the VirtualBox Guest Additions software.

Getting Guest Additions to work with a new virtual machine can often be a tricky affair, so do not get frustrated and give up. If you want to link VBoxGuestAdditions.iso to a new virtual machine, first make sure the VM is closed.

With its rich suite of malware analysis and scanning tools, doubtless REMnux 6 will soon be part of every security analyst’s arsenal.
