Palo Alto Networks® WildFire® now supports a new office file type analysis classification engine for WildFire Inline ML: OOXML (Open Office XML). This enables you to configure your NGFW to detect and prevent malicious Office Open XML files from entering your network in real-time by applying machine learning (ML) analytics. WildFire Inline ML dynamically detects malicious files of specific types by evaluating various file details to formulate a high probability classification of a file. This protection extends to currently unknown as well as future variants of threats which match characteristics that Palo Alto Networks identifies as malicious. To take advantage of WildFire inline ML, you must have an active WildFire subscription. If you do not have WildFire Inline ML enabled on your firewall, refer to WildFire Inline ML for more information.
