It's possible to block custom file hash-256 in Palo alto.

Please let me know how I can check the respective file hashes disposition at a wildfire, either it is in block or not.


Here is below the file hashes need to know for disposition.

Unfortunately you can not create a custom threat signature based on a file hash.


At least some of the hashes you reference already have Anti-Virus signatures.  You can investigate signature availability at


If you have the actual sample you can submit it using the wildfire portal so a signature can be generated.


If you are a Cortex XDR customer, you can black list the file hashes on your endpoints.

Thanks for your comments. Much Appreciated|||

I have studied and found no way to block custom files based on hash-256 only.

As per document file can block but based on patterns of specific file types.


In my case, these Hash-256 only of near firms which recently attacked by these files and damaged therefore it needs to be blocked at my end as well to avoid any risk.


I found few of them are blocked in wildfire but not all, so how I can add all in block state while having no file sample or pattern.

Please advise the way to block all these hashes-256 without a sample or pattern.


Your prompt response will be highly appreciated.

The only way to block a file by hash is if you have Cortex XDR on the endpoint.


One feature that might possibly help is the new MLAV feature in PAN-OS 10.0.  Here is the information:




I think it can be helpful, if converting the hash into HEX and create a custom vulnerability to drop anything that matches the file hashes.


And I have noticed, few of the hashes are already listed in Cisco Talos File Repute but not in PA Threat Vault.
