WildFire Appliance Script Support

The WildFire appliance (private cloud) can now analyze and classify script files with verdicts using static and dynamic analysis. Previously this feature was only present in the WildFire cloud. This analysis capability has now been expanded to include WildFire appliances running PAN-OS 9.0.4 and later.
When a malicious script is discovered during analysis, the WildFire appliance 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.
  • Only firewalls operating PAN-OS 9.0.4 and later can analyze scripts.
The WildFire appliance is capable of analyzing the following script types:
  • JScript (.js)
  • VBScript (.vbs)
  • PowerShell Script (.ps1)
To forward script files for analysis, the
WildFire Analysis Profile
on the firewall must be configured to forward the
file type or
unknown files to the WildFire private cloud.
  1. Enable file type forwarding.
    1. Select
      Objects > Security Profiles > WildFire Analysis
      or modify a profile to define traffic to forward for WildFire analysis.
    2. Add or modify a profile rule, select

      , and set the rule to forward the new
      file type. You can also specify the
      file type if you want to forward only scripts.
      Profile rules with the file type set to
      forward all file types for WildFire analysis.
    3. Select Destination and set the profile rule to forward the files to the
    4. Click
      to save the new or modified WildFire Analysis profile.
  2. Attach the WildFire Analysis profile to a security policy rule—traffic matched to the policy rule is forwarded for WildFire Analysis.
    1. Select
      Policies > Security
      or modify a security policy rule.
    2. Select
      and set the
