Behavioral threat detected (rule: bioc.syscall.remote banker behavior)

Hi Guys, 

 

In the Cortex XDR, we are getting an alert indicating Behavioral threat detected (rule: bioc.syscall.remote banker behavior). Although the file is blocked which is benign, the is no information related to the rule. Does anyone have a clear idea about the rule?

 

Regards

Hi There,

 

We would recommend you to open up a support case with palo alto where you will have to submit the alert data for them to investigate.

 

The rule which you have mentioned alone does not signify much as this is a friendly name to one of the rule set in EDR.

I have already opened the case with them and they confirmed my case as a FP but the issue is that there is no explanation about it. As long as there is no explanation, it cannot be decide whether the alert is a FP or a real threat. 

Did you have an alert around the same time on the same endpoint? If yes, can you post the details on that alert?

@KanwarSingh01 my apologies if I missed it, but is there a central location or notification of what the list of BTP rules looks like?  What is their contents?  When were they applied, etc?  Perhaps I am totally missing it, but I don't know where to find that.  Weather its for this particular one or ANY BTP rule (Behavioral threat detected (rule: bioc.syscall.entrypoint_patching) OR Behavioral threat detected (rule: heuristic.agb.5637) OR Behavioral threat detected (rule: accessibility_feature_escalation), etc

I mean the name has some clue to what its doing but is there insight as a Cortex XDR admin, you have of them and the BTP list looks like?  What they do, when they were last changed or had updates to them?


thank you

Hi KRisselada, 

 

You cannot find any list of BIOC rules per my knowledge and a follow up with Palo Engineers. These are preconfigured rules from Palo Alto Networks with no intention to share (if they share, protection would go undermine). 

 

Regards
