Basic File Report

This sample invokes and displays the results of a VirusTotal "file report" via DXL.

See File Report Documentation for more details.

The majority of the sample code is shown below:

Sample Code

# Create the client
with DxlClient(config) as client:

    # Connect to the fabric
    client.connect()

    logger.info("Connected to DXL fabric.")

    # Invoke 'file report' method on service
    request_topic = "/opendxl-virustotal/service/vtapi/file/report"
    req = Request(request_topic)
    MessageUtils.dict_to_json_payload(req, {"resource": "7657fcb7d772448a6d8504e4b20168b8"})
    res = client.sync_request(req, timeout=30)

    if res.message_type != Message.MESSAGE_TYPE_ERROR:
        # Display results
        res_dict = MessageUtils.json_payload_to_dict(res)
        print(MessageUtils.dict_to_json(res_dict, pretty_print=True))
    else:
        print("Error invoking service with topic '{0}': {1} ({2})".format(
            request_topic, res.error_message, res.error_code))

After connecting to the DXL fabric, a request message is created with a topic that targets the "file report" method of the VirusTotal API DXL service.

The next step is to set the payload of the request message. The contents of the payload include the resource to report on (in this case, an MD5 hash).

From the VirusTotal file reports documentation:

"A md5/sha1/sha256 hash will retrieve the most recent report on a given sample. You may also specify a scan_id (sha256-timestamp as returned by the file upload API) to access a specific report. You can also specify a CSV list made up of a combination of hashes and scan_ids (up to 4 items with the standard request rate), this allows you to perform a batch request with one single call."

The final step is to perform a synchronous request via the DXL fabric. If the response message is not an error its contents are displayed.

Output

The output should appear similar to the following:
