virustotal

virustotal is a Python module to use the Virustotal public API, a free service that analyzes files from malwares.

Prerequisites

You need to get an API key to use the VirusTotal Public API 2.0. To do so, just sign-up on the service, go to your profile and click on API Key.

How to use

Install

Install virustotal using setuptools' related softwares.

pip install virustotal
easy_install virustotal

or clone this repos

git clone git://github.com/Gawen/virustotal.git
cd virustotal
python setup.py install

Import

Import the virustotal module

import virustotal

Instantiate the handler's class.

v = virustotal.VirusTotal(YOUR_API_KEY)

Get a report

Use the method get(). Its first parameter can be :

A hash (MD5, SHA1, SHA256)
A scan-id (VirusTotal's scan UID)
A file object (file, socket, StringIO)
A file path or URL

For example,

# Filepath
report = v.get("/foo/bar")

# EICAR (see Links section)
report = v.get(StringIO.StringIO("X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*"))

# EICAR's MD5 (see Links section)
report = v.get("44D88612FEA8A8F36DE82E1278ABB02F")

Scan a file

Use the method scan(). Its first parameter can be :

A file object (file, socket, StringIO)
A file path or URL

For example,

# Filepath
report = v.scan("/foo/bar")

# EICAR (see Links section)
report = v.scan(StringIO.StringIO("X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*"))

You can set its parameter reanalyze to force VirusTotal to re-scan the file.

# Force to re-scan EICAR (see Links section)
report = v.scan(StringIO.StringIO("X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*"), reanalyze = True)

Report object

A report (instance of Report) is returned by the method get() and scan().

During a scan, the final report is not returned immediatly because VirusTotal needs time to send you the results. You can know if a report is done using the parameter done.

if report.done:
    # Read the report

You can wait for the report to be done using the join() method.

# Wait for the report to be ready
report.join()
assert report.done == True

Then, you can use the report to get the results:

print "Report"
print "- Resource's UID:", report.id
print "- Scan's UID:", report.scan_id
print "- Permalink:", report.permalink
print "- Resource's SHA1:", report.sha1
print "- Resource's SHA256:", report.sha256
print "- Resource's MD5:", report.md5
print "- Resource's status:", report.status
print "- Antivirus' total:", report.total
print "- Antivirus's positives:", report.positives
for antivirus, malware in report:
    if malware is not None:
        print
        print "Antivirus:", antivirus[0]
        print "Antivirus' version:", antivirus[1]
        print "Antivirus' update:", antivirus[2]
        print "Malware:", malware

Use as a client CLI

You can use virustotal.py as a CLI program to get report or scan files in VirusTotal.

usage: python virustotal.py (get|scan) [resource]

resource can be:

A hash (MD5, SHA1, SHA256)
A scan-id (VirusTotal's scan UID)
A file path or URL

To ask VirusTotal to get the EICAR file report (see Links section).

python virustotal.py get 44D88612FEA8A8F36DE82E1278ABB02F

Or test if this repository is virus-free ;-)

python virustotal.py scan *
