$ . ./venv/bin/activate
(venv) $ pip install -r requirements.txt

If an error occurs... try:

error: cffi.VerificationError: CompileError: command 'x86_64-linux-gnu-gcc' failed with exit status 1

$ sudo apt install libfuzzy-dev

Cuckoo sandbox execution

cuckoo.py has to be run on another window before running FUMVar.py.

(venv) $ python cuckoo.py

How to run

Before you run the code you have to insert the VirusTotal api key to the vt_api_key file. You can add multiple VirusTotal api key in vt_api_key.

$ vim vt_api_key

#### insert your api key ####

after insert VirusTotal api key. This is an example, these keys are not valid.

$ vim vt_api_key

...

You can see the information by running FUMVar with --help option.

(venv) $ python FUMVar.py --help

usage: FUMVar.py [-h] -i INPUT_PATH -o OUTPUT_PATH [-p POPULATION]
                 [-m PERTURBATION] [-g GENERATION] [-s SKIP]

optional arguments:
  -h, --help       show this help message and exit
  -i INPUT_PATH    Path for binary input
  -o OUTPUT_PATH   Path for result
  -p POPULATION    Number of population (default=4)
  -m PERTURBATION  Number of perturbation per generation (default=4)
  -g GENERATION    Number of generation (default=100)
  -s SKIP          Number of skip time for VirusTotal scan generation
                   (default=5)

Sample code for running and result
