@Joshan_Lakhani,

 

Unfortunately, right now there no option to block file hashes in Palo Alto. You can try by creating Custom Signature for your use case.

Is any document for Customer  signature to block this hash

@Joshan_Lakhani,

 

Actually it is not possible to create custom Signature in PA based on file hash value. But yes there are options custom signatures based on file types patterns. Please refer below articles.

Hello,

Take a look at a program that blocks on these features. Maybe block it with your AV or some other app whitelisting application such as bit9.
