Update: virustotal-search

Filed under: Malware,My Software,Update — Didier Stevens @ 9:04

I didn’t expect my virustotal-search program to be that popular, so here is a new version with new features and a few fixes (version 0.0.1 contained a buggy experimental feature I hadn’t planned to release then).

What I didn’t explain in my first post, is that virustotal-search builds a database (virustotal-search.pkl) of all your requests, so that recurring requests are served from that local database, and not from the VirusTotal servers. I’ve added a field (Requested) to indicate if the request was send to VirusTotal or served from the local database.

If you want all requests to be send to VirusTotal, regardless of the content of the local database, use option –force.

And if you don’t want to include your API key in the program source code, you have two alternatives:

  1. use option –key and provide the API key on the command line
  2. define environment variable VIRUSTOTAL_API2_KEY with the your API key

  2. Hi Didier,

    I’ve added my feature to your version 0.0.3. Instead of -f it is now called -g ‘genhash’. Also added a -s –short feature. This will cause the program to only print the hash, score and url. If you like it perhaps its worth adding to your blog. With this new functionality I will be able to use it at work tomorrow to determine if a binary was already uploaded to VT and see the score directly.

    Next couple of days I’ll spend reading some more of your blog. Curious what you write about.

    Here’s my version: http://pastebin.com/nw92G0QX

    Regards,

  4. @TecToDo Thanks, I’ll take a look & merge, maybe with some tweaks.

  6. As you know VT stores multiple scans per file. Do you know of any way to get only the results from the first scan of a list of hashes? Your script returns the latest scan result per file.

  7. @embrollo My script uses VirusTotal’s Public API version 2.0. When searching for a hash, that API returns the most recent scan:
    > a md5/sha1/sha256 hash will retrieve the most recent report on a given sample.

    To access a given report, you need to know the scan_id:
    > You may also specify a scan_id (sha256-timestamp as returned by the file upload API) to access a specific report.

  8. Thanks for the answer Didier. Unfortunately that’s not exactly what I’m looking for as I won’t know the scan_id beforehand. I’ll get in touch with Emiliano & Julio to see if they can add that feature to the API.
