cortex xdr - submit false positive - shuttools 1.81

[thejackal]

Palo Alto I am having a problem with your program mis classifing my tool suite

Shut.Tools.1.81.docm

as a false positive.  Its a vba macro that has previously been clearing my Microsoft and utilises some MVP code.  I depend on this to undertake my tasks and is currently being flagged as a false positive by cortex xdr.  Previously traps did cause many if at all issues.  As mentioned Microsoft have cleared a previous version of the macro.

it is critical that you take a look at this program as it performs no malicous activity, its main role is to generate documents for our shutdown planning process at work.  It also uploads source to github and a few other things however does not contain any malicous code.

I have been able to dig this out of the cortex xdr log

Hello @thejackal were you not able to get a reply when submitting it as a WildFire Verdict review?  
I normally find this process works pretty well, if the item in question created a Incident in Cortex.  The process I normally am able to use is mentioned in this thread:    https://live.paloaltonetworks.com/t5/cortex-xdr-discussions/submit-a-revision-about-false-positive-m...

Apologies if done this already or this is not relevant to the issue your posting on.

if I can add my other 2cents to this, what I have found is that when app has not been signed by the vendor (which this one is not), its very much likely that WildFire is going to default to considering it Malware, unless a Verdict review is submitted. I have been told by PA TAC/Support folks that the best way to ensure WF has better results, is to ensure and we all request our software vendors to ensure they sign their files.

Hi @thejackal,

@KRisselada is correct.  You have two options here.  You can whitelist the file within your own environment or you can report the verdict as incorrect to WildFire.  If you report it as incorrect, members of our Unit42 team will examine the file in more depth to possibly update the verdict.  

You mentioned that you did not have issues with Traps and they the problem occurred with the current iteration of the product.  I think this is because Cortex XDR has more methods to detect threats such as the Behavioral Indicator of Compromise (BIOC).  When a certain behavior matches these rulesets, you may have additional alerts that were not there in Traps.

In any case, it is worth submitting the app for additional review since it is a needed application.

Palo Alto,

it seems after some recent updates/changes the file is again being flagged as a false positive.  I suspect as the hash has changed somewhat since last update of your system.

Would you please assist me in having this rectified as it is indeed being flagged as a false positive and is a required application to undertake my job function.  I have included the 2 most up to date versions inclusive of beta of the Shut.tools app.  Hopefully this should clear both versions of this from being flagged as a false positive.  Your assistance is greatly appreciated.
