The WildFire public cloud can now analyze and classify script files with verdicts using static and dynamic analysis. When a malicious script is discovered, the WildFire cloud generates and distributes C2 and DNS signatures to firewalls to prevent successful script-based attacks. Because C2 and DNS signatures look at key network behaviors contained within samples, these signatures can detect activity in previously unknown malicious scripts. To ensure that you are protected from the latest threats, always keep your firewalls up-to-date with the latest content and software updates from Palo Alto Networks.
- The WildFire appliance does not support script file analysis at this time.
- Only firewalls operating PAN-OS 8.1 and later can forward scripts to the WildFire public cloud.
The WildFire cloud is capable of analyzing the following script types:
- JScript (.js)
- VBScript (.vbs)
- PowerShell Script (.ps1)
