The quantity and maximum size of files
that a firewall can forward to WildFire is increased to provide
greater visibility and detection of uncommonly large malicious samples.
WildFire Appliance Archive Support
The WildFire appliance can now analyze and classify RAR and
7-Zip archives, which can be used by an adversary to covertly
deliver malicious payloads to users. When the WildFire appliance determines
that the file contents of an archive are malicious, it generates
a signature for the entire archive. The appliance then provides
the signature to all connected firewalls to prevent future attacks.
