Installing the Linux host

First prepare the networking for your machinery platform on the host side. If you use VirtualBox with e.g. host-only interfaces and you have a vboxnet0 interface, you do not need to install additional dependencies.

If you use QEMU, you may need to install additional dependencies on the host:

$ sudo apt install uml-utilities bridge-utils

Next, get the list of virtual machines for which to configure the interface from conf/qemu.conf. For example, ubuntu_x32, ubuntu_x64, ubuntu_arm, ubuntu_mips, ubuntu_mipsel, et cetera. For each VM, preconfigure a network tap interfaces on the host, required to avoid have to start as root, e.g.:

$ sudo tunctl -b -u cuckoo -t tap_ubuntu_x32
$ sudo ip link set tap_ubuntu_x32 master br0
$ sudo ip link set dev tap_ubuntu_x32 up
$ sudo ip link set dev br0 up

$ sudo tunctl -b -u cuckoo -t tap_ubuntu_x64
$ sudo ip link set tap_ubuntu_x64 master br0
$ sudo ip link set dev tap_ubuntu_x64 up
$ sudo ip link set dev br0 up

Note that if you run Cuckoo as a different user, replace ``cuckoo`` after -u with your user.

Preparing x32/x64 Ubuntu 18.04 Linux guests

Ensure the agent automatically starts. The easiest way is to add it to crontab:

$ sudo crontab -e
@reboot python /path/to/

Install dependencies inside of the virtual machine:

$ sudo apt-get install systemtap gcc patch linux-headers-$(uname -r)

Install kernel debugging symbols:

$ sudo apt-key adv --keyserver --recv-keys C8CAB6595FDFF622

$ codename=$(lsb_release -cs)
$ sudo tee /etc/apt/sources.list.d/ddebs.list << EOF
  deb ${codename}          main restricted universe multiverse
  #deb ${codename}-security main restricted universe multiverse
  deb ${codename}-updates  main restricted universe multiverse
  deb ${codename}-proposed main restricted universe multiverse

$ sudo apt-get update
$ sudo apt-get install linux-image-$(uname -r)-dbgsym

(For Debian 9 amd64) Install kernel debugging symbols:

$ sudo apt-get install linux-image-$(uname -r)-dbg

Patch the SystemTap tapset, so that the Cuckoo analyzer can properly parse the output:

$ wget
$ wget
$ sudo patch /usr/share/systemtap/tapset/linux/sysc_execve.stp < expand_execve_envp.patch
$ sudo patch /usr/share/systemtap/tapset/uconversions.stp < escape_delimiters.patch

Compile the kernel extension:

$ wget
$ sudo stap -p4 -r $(uname -r) strace.stp -m stap_ -v

Once the compilation finishes you should see the file stap_.ko in the same folder. You will now be able to test the STAP kernel extension as follows:

$ sudo staprun -v ./stap_.ko

Output should be something like as follows:

staprun:insert_module:x Module stap_ inserted from file path_to_stap_.ko

The stap_.ko file should be placed in /root/.cuckoo:

$ sudo mkdir /root/.cuckoo
$ sudo mv stap_.ko /root/.cuckoo/

Disable the firewall inside of the VM, if it exists:

$ sudo ufw disable

Disable NTP inside of the VM:

$ sudo timedatectl set-ntp off

Optional - preinstalled remove software and configurations:

$ sudo apt-get purge update-notifier update-manager update-manager-core ubuntu-release-upgrader-core
$ sudo apt-get purge whoopsie ntpdate cups-daemon avahi-autoipd avahi-daemon avahi-utils
$ sudo apt-get purge account-plugin-salut libnss-mdns telepathy-salut

It is recommended to configure the Linux guest with a static IP addresses. Make sure the machine entry in the configuration has the correct IP address and has the platform variable set to linux. Create a snapshot once the VM has been configured. It is now ready for analysis!
