MITRE and NIST have been putting some efforts into the "Malware Attribute
Enumeration and Characterization (MAEC)" standard. I haven't done much work
with it, but it's worth looking into. They have a list of datasets at

Sending the hashes out to services like VirusTotal or Team CYMRU is another
widely used option. This is all covered under the Bro File Extraction
Exercise on the website (https://www.bro.org/current/exercises/faf/)

If you are trying to do this without sending any information over the
internet, there are in-house implementations that are available for
commercial use. Opswat Meta-defender is an example of a commercially
available multi-AV platform with an API that Bro can interface with.

Hope this helps.
