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.
