virustotal2 1.0

Complete, Pythonic VirusTotal Public API 2.0 client

Latest Version: 1.1

A portable, Pythonic and complete implementation of the Virustotal Public API. It would also implement the Private API if VT would like to give me access… :)

This module is heavily inspired by, and borrows some code from, the virustotal module. In particular, it uses the same rate limiting logic and deals with report updating in the same way. I ended up re-writing the module from scratch, however, and in the process made some new choices that broke backwards compatibility. Thus, we have virustotal2.

Prerequisites

Example

import virustotal2
import urllib2
import csv

vt = virustotal2.VirusTotal2("b2510b80fec019d8b6896a8e575022690efecdfa858d1077c75b37dae5f4621e")

mdl_content = urllib2.urlopen("http://www.malwaredomainlist.com/updatescsv.php")
mdl_csv = csv.reader(mdl_content)

for line in mdl_csv:
    ip=line[2].split("/")[0]
    try:
        ip_report = vt.retrieve(ip)   #get the VT IP report for this IP
    except:
        print "API error: on ip " + ip

    total_pos = sum([u["positives"] for u in ip_report.detected_urls])
    total_scan = sum([u["total"] for u in ip_report.detected_urls])
    count = len(ip_report.detected_urls)

    print str(count)+" URLs hosted on "+ip+" are called malicious by (on average) " + \
          str(int(total_pos/count)) + " / " + str(int(total_scan/count)) + " scanners"

How To Use

Install

pip install virustotal2

Import

import virustotal2

Instantiate

vt2=virustotal2.VirusTotal2(API_KEY)

Optionally, you can pass limit_per_min, which is the number of queries you can perform per minute. 4 is the default.

Retrieve a report

Use the method retrieve() to get an existing report from VirusTotal. This method’s first argument can be:

  • an MD5, SHA1 or SHA256 of a file or a list of up to 4 hashes
  • a path to a file or list of paths to files
  • a base64-encoded version of a file or list of paths to files (filename must end in .base64!)
  • a URL or a list of up to 4 URLs
  • an IP address
  • a domain name

retrieve() will attempt to auto-detect what you’re giving it. If you want to be explicit, you can use the thing_type parameter with the values:

  • ip
  • domain
  • hash
  • file
  • base64
  • url

Finally, if you want raw JSON back, as opposed to a VirusTotal2Report object, you can pass in raw=True.

If you pass retrieve() a list of items, you will get a list of reports back in the same order.

Scan a new file

Use the scan() method to scan a new URL or file. This method’s first argument can be:

  • a path to a file
  • a url or list of up to 4 URLs
  • a hash or a list of up to 25 hashes (for re-scanning only!)

scan() will attempt to auto-detect what you’re giving it. If you want to be explicit, you can use the type parameter with the values:

  • file
  • base64
  • url

If you want raw JSON back, as opposed to a VirusTotal2Report object, you can pass in raw = True.

Finally, if you want force a reanalysis of the resource you are passing in, set rescan = True. Note that the VirusTotal API currently does not allow URLs to be reanalyzed.

If you pass scan() a list of items, you will get a list of reports back in the same order. In order to preserve that semantic, if you pass in a list of files, some of which are invalid, you will get a list of reports and None back.

Using a Report

The retrieve() and scan() methods return VirusTotal2Report objects. These objects have some useful methods and also act as pass-thrus to the underlying JSON.

wait()

This method blocks until the file or URL you’ve submitted for scanning is finished scanning. THIS CAN TAKE A VERY LONG TIME.

rescan()

requests virustotal to rescan the sample that created the current report. This is only valid for file or hash reports. This method modifies the current report rather than returning a new report object, so the following is normal:

>>> import virustotal2
>>> vt = virustotal2.VirusTotal2(API_KEY)
>>> report = vt.get("www.evilsite.com/evil.exe")
>>> report.status()
analyzing
>>> report.wait()
>>> report.status()
ok
>>> report.rescan()
>>> report.status()
analyzing
>>> report.wait()
>>> report.status()
ok

update()

checks to see if virustotal has completed it’s analysis yet and if so it pull down the new JSON.
