Re: [cti-cybox] A new Forum Object

[Paul Patrick <ppatrick@isightpartners.com>]

I’m very supportive of a new CybOX object that can be used to represent posts on Forums and blogs and see it to be very differently from a message like one would see in messaging system.  I’ve been talking to the MITRE folks for a couple of years now about adding support to capturing forum/blog posts and how they differ from things like Twitter, Facebook Messenger, and Email.

 

I think Terry’s proposed first cut is pretty good but would recommend adding the properties “created_at” to indicate when the post was created and possibly “modified_at” to indicate the last time the post was modified.

Hi All,

 

For the 3rd time someone recently asked me if there was a way of encoding web forum posts within CybOX. My reply...well not really. That answer bothered me greatly, so with the help of AJ from EclecticIQ I put together a Forum Object.

 

The Forum Object is designed to record web forum and newsgroup posts, and is aimed primarily at helping people record what is being discussed on underground forums. 

 

I really think it is needed for CybOX 3.0 MVP personally, and a couple of friends at very large organizations have also confirmed they would find this very useful. In fact one was surprised that it wasn't there already.

1.1 Forum Object

Type Name: forum-object

Status: Draft MVP: Yes

 

The Forum Object represents a single Forum post. It is used to capture posts on newsgroups and web forums, primarily to enable the sharing of conversations held between threat actors on underground forums.
