Cortex XSOAR Context Issue

[Rawabdeh]

Hi Everyone, 

I have Cortex XSOAR with SplunkPY running and fetching incidents. I am using Splunk classifier and Splunk incoming mapper by default. 

Drill down is being enriched successfully and i can see it parsed at both classifier & mapper stages - see below screenshot

drilldown parsed in classifier&mapper

However, context is not splitting drill down details , It's all coming in one chunk of data and cannot be used in any playbook. - Below screenshot

drilldown nor parsed in context

Any ideas what might be causing this? Is there anywhere else to check that might affect Drilldown parsing in context?

I think you have a transform issue.  

Look at the following link on YouTube to MOD44's PCSAE - Palo Alto Networks - Certification- Training- Domain 1 

Skip ahead to 34:15, I think this will help you.

@Strunce thank you for your reply. 

This video discusses splitting data at classifier level, but I have that already applied in my classifier & mapper as per the above screenshots. No transformations are present within my classifier or mapper. 

I just created a complete new account with fresh installation and integration with a totally different Splunk instance and the same issue persists. 

Do you happen to know how data is filled into context and what controls this process? should I dig into automations for pre-processing rules?

Hi @Rawabdeh , the fields you are showing (incident -> labels -> drilldown) are not being mapped. By default, each mapper has a couple of fields mapped. The rest of the fields are copied verbatim into the context data under "labels". This setting can be disable (if you wanted to) under the settings of the mapper under Advanced:

All data under the labels will be as presented by the source technology. If you would like the data parsed, you would need to alter the Splunk incoming mapper to map that field.

Do you know how you would like the data presented? As a table perhaps?

Thank you for your contribution @ABurt 

Actually drill down is supposed to look like the first screenshot (I'm using it in my playbooks as Drilldown.[0].Country.[0] >> maps to: Saudi Arabia in the first screenshot)

I have tried checking that box you mentioned and indeed, it stopped throwing all JSON details under incident.labels and I was able to use the custom field (mapped with drilldown values) I created. But that means I have to create a field for each value in each alert coming from Splunk and i don't think that's a feasible solution.

What's confusing me is that context had drill down parsed just the way it's seen in mapper and I built my playbooks based on this format. Out of nowhere it noticed empty data in sub-playbooks and found out about this issue. No changes were applied on any account
