Who likes dependencies anyway??? Not me…so here is a shell script to get Cuckoo Sandbox v1.1 installed

by on Jun.23, 2014, under General

I realized that I was spending an inordinate amount of time when rebuilding Cuckoo Sandbox ( in my home lab just because I was starting from a fresh Ubuntu install which does not ship with all of the dependencies and packages that are required by Cuckoo. I also break this system quite often and in such specular ways that the only recovery mechanism is to rebuild the system from the OS up. This, unfortunately, also leads back to spending way too much time post-OS install in rebuilding Cuckoo. There has to be a better way…and so there is using a shell script I wrote to get me up and running in no time after a rebuild.

So what do I need to run this script?

The script (located here: cuckoo_install – right-click and save as, rename to .sh) assumes you have a base install of Ubuntu 12.04LTS and that you have updated through an apt-get update and an apt-get dist-upgrade. It was also created to work specifically for Cuckoo Sandbox v1.1.  Beyond that you’re on your own to set networking and the user accounts as you see fit. In my case I use the account created during OS install for everything on this system and I have a physically and logically segmented network just for the sandbox and the virtual machines used to detonate the malware. These systems are directly connected to the internet and sit behind a Cisco ASA which is logging all accepts and denies to a Splunk instance and the connection is tapped using a VSS 12×4 distributed tap and the traffic is captured using the free version of NetWitness Investigator. I’m also running a VM instance of INetSim ( that supplies DNS, FTP, and other services that may be required by the malware (i.e. through faking a DNS response to point the malware to a system I control).

What happens when I run the script?

Assuming your base Ubuntu system has connectivity to the internet it will proceed to download and install all of the required dependencies and packages required to run Cuckoo Sandbox v1.1 (again, this assumes you’re on 12.04LTS as a base OS). There is a built-in check at the start that will verify your version that will error out if you’re on something other than 12.04LTS. If you think this will work even if you’re not on 12.04LTS you can, at your own risk, comment out this section and force the script to run. The script runs in sections and requires that you hit enter before proceeding to the next section. I put this in so you could review the status of a section (i.e. no errors) before continuing on to the next section of the script. If you find that annoying simply comment out all of the “read” commands in the script and it will run start to end, however it becomes difficult to identify any install errors given the length of the output. Other than that the script will install what is required for Cuckoo, and after running you can address and errors or issues with the installed components to ensure everything is installed correctly.

What do I need to do following the script to get Cuckoo up and running?

This is going to be highly dependent on your individual setup, however you need to get your virtual machines built and/or transferred into VirtualBox and set the snapshots that will be used (plenty of good info on the net on this step such as You also need to add your user account to the virtualbox group, download the file if you plan on using Volatility, and setup your network for your particular needs.

Can I modify the script and/or what if it doesn’t work?

I’m posting this script as-is. It works for my needs in my lab environment which may not be the same as yours. Feel free to mod it as required, however all I ask is if you make significant improvements to the script that you share it back to the community. I’m not going to actively maintain the script or make modifications in the future as this is a one shot deal (I have a $dayjob that actually pays the bills).

Note: If you’re new to Cuckoo or Ubuntu I’d actually recommend trying a manual install if you have time. I realized I learned quite a lot about the required packages and how the system functions when I struggled to get Cuckoo up and running a few years ago. It makes troubleshooting issues I encounter now much easier.
