[PEGA 7.1.6] Check File Signature (MIME Type) to Determine File Type Before Upload
Hello,
Is there an OOTB Activity or function that can validate the file signature (MIME Type) to determine that only valid files (not EXE, etc.) are being uploaded using the OOTB Attach Control? Or must this be done with custom code? If custom, can you lend any insight as to what that custom code would look like? We are already checking file extension, but in some cases that is not enough.
Thank you!

Hi Fran,
There is an extension point activity Data-WorkAttach-File.CallVirusCheck that you can override to add whatever you would like before processing the attachment. See the following link for more details:

Overriding the CallVirusCheck is an option, but how can refer to the mimetype of the attachment? There is a property pyAttachMimeType but when i look in the clipboard after attaching a file, i can't find it...

Hello Fran,
Did you already find a solution for your problem? I am trying to check wether the uploaded file is a PDF-type. But I can't find out how?

Hi Martin,
I can tell you a crude way of doing this. Write an Obj-Validate and check what comes after last the '.'. If it's not pdf then fire validation message. You have to use this validate rule in pyAttachContent flow action.
Hope this helps.
