Pretty simple need here....
Installing the latest version of WSUS Automated Maintenance from AJ Tek on our WSUS server and Cortex is blocking it with the description "Suspicious executable detected". How do I allow this to install? Is the best way to temporarily pause protection on the endpoint, install the software and then re-enable protection?
I think can depend how your environment is setup. you potentially could use the "report verdict as incorrect" in the incident... or could whitelist the hash... now if your setup to not allow unsigned app and that is unsigned that would be different. sorry for being slightly vague but some of this depends on your environment.
As suggested above, you can add files hashes to your allow list. Adding files to the block list or allow list takes precedence of any other policy rules that may have otherwise been applied to these files.
In order to add file hashes to your allow-lists:

Hi @cemcga ,
Let me jump in and clarify @PeteJacobCF reply:
- Report incorrect verdict is applicable only if the prevention is triggered by the WildFire. If Wildfire verdict is unknown at the time of the execution (or WF is unreachable) XDR agent will perform static analysis, called Local Analysis. Local Analysis is using machine learning models to search for suspicious behavior in the exe. It is very common for local analysis to trigger false positive for legitimate file.
- If the execution is blocked by Local Analysis, reporting verdict to WF is not applicable here. As @PeteJacobCF mentioned the solution in this case it to add the file hash to the allow list.
In my humble opinion - if you absolutely trust this file and want execute it on a machine, then it should be safe to allow this file hash globally. So the easiest way would be to add it to the allow list, wait for the xdr agent to check-in (to get the update from the cloud console).
