WildFire Appliance Archive Support

The WildFire appliance running PAN-OS 9.0 or later can now analyze and classify RAR and 7-Zip archives, which can be used by an adversary to covertly deliver malicious payloads to users.
The WildFire appliance can now analyze and classify archive (RAR and 7-Zip) files with malicious, benign, or grayware verdicts. 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 and later.
  • When any file contained within an archive is determined to be malicious, the archive file is considered malicious by WildFire.
  • Archive files that are multi-part or password protected cannot be analyzed.
The WildFire appliance is capable of analyzing the following archive file types:
  • RAR—Supports Roshal Archive (.rar) files.
  • 7-Zip—Supports (.7z) files.
To forward archive files for analysis, the WildFire Analysis Profile on the firewall must be configured to forward the archive file type or Any unknown files to the WildFire private cloud.
  1. Enable file type forwarding.
    1. Select Objects > Security Profiles > WildFire Analysis and Add or modify a profile to define traffic to forward for WildFire analysis.
    2. Add or modify a profile rule, select file type, and set the rule to forward the new Any file type. You can also specify the archive file type if you want to forward only archives.
      Profile rules with the file type set to Any forward all file types for WildFire analysis.
    3. Select Destination and set the profile rule to forward the files to the private-cloud.
    4. Click OK 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 and Add or modify a security policy rule.
    2. Select Actions and set the Profile Type to Profiles.
    3. Select the newly-created WildFire Analysis profile.
    4. Click OK to save the security policy rule.
      For detailed steps to configure a WildFire Analysis profile and to attach the profile to a security policy rule, see Forward Files for WildFire Analysis.
  3. Select Monitor > WildFire Submissions to find WildFire verdicts and analysis reports for archive files that have been submitted by the firewall.
