BIOC - Powershell Script Based Alert Detection

[KanwarSingh01]

We know that Cortex has the ability to use AMSI but is any one able to achieve a BIOC rule which can trigger an alert for the content inside the script.

Lets say if a Powershell script which is being run has certain parameters in the body such as "replace","Download","Invoke-WebRequest" etc...

Is it possible to create a BIOC rule for the content inside in the script?

Thanks in Advance.

Hi KanwarSingh01,

The Cortex XDR Agent features Behavioral Threat Protection modules leveraging the Anti-Malware Scan Interface (AMSI) to block PowerShell scripts.

To create a BIOC rule, please check out Live Community How-to video Script Block Query and BIOC | Palo Alto Networks
