Cortex XDR to block the download of particular executable files

[RahulPrajapati]

Hi everyone,

As we know that XDR agent can block the execution of any particular executable files but can anyone let me know whether XDR agent can block the download of any particular executables like winrar.exe, ccleaner.exe, etc. from any source like websites, email attachment, etc ?

Regards

Hi @RahulPrajapati ,

With Cortex XDR protection process on attaching its protection during write/create/read, I think this is not currently possible. 

What you can do is to add it the hash on block list and Cortex XDR will block during execution and upon scan.

Hi @MarvinC ,

Thanks for your response !

Just to add on what @MarvinC suggested. You can create a BIOC rule which can alert on file write operation of the desired applications. Please note file write/create operation via BIOC will be a "detection rule" which will trigger an alert in the alerts table if the severity is Low for a detection rule.
