Logstash and VirusTotal


(sampasei) #1

Hi All,
i've tried to use Lostash 2.0 with VirusTotal plugin


without any result.
Here my config file snippet:

    virustotal {
            apikey => "myapikey"
            field => [src_ip]
            lookup_type => "url"
            target => "virustotal"
    }

Below the error code

`Exception in filterworker, the pipeline stopped processing new events, please check your filter configuration and restart Logstash. {"exception"=>#<JSON::ParserError: A JSON text must at least contain two octets!>'

JSON::ParserError: A JSON text must at least contain two octets!

  start_filters at /opt/logstash/vendor/bundle/jruby/1.9/gems/logstash-core-2.0.0-java/lib/logstash/pipeline.rb:154

How can i avoid this error?
Thanks

Since this error originates in the virustotal plugin perhaps you should contact its author? Reading the plugin's source code it looks like it blindly assumes that it gets a non-empty response from the server but that doesn't seem to hold true in your case.
