Skype: block file transfer !

L2 Linker

Dear DevCenter,

I need you to define App-ID for transfer file in skype. In yahoo-im App, I see the yahoo-file-transfer App-ID, but not in Skype.

Please help.

I submitted 1 new app (by that URL)  3 or 4 months ago but no one care about it. I did not receive any feedback from palo alto.

get in contact with your SE. They can ask PAN for more information...

Hi Hithead,

I think is gonna be difficult, skype uses a proprietary implementation and doesn't follow any RFC so first of all the PAN firewall needs to decrypt the sesion [if the skype client uses certificate pinning you're  almost screwed] and after that  need to reverse engineering the protocol.

useful links,

allow Skype and Block Skype VoIP and file sharing


Found a bit old topic but if anyone should still need to block Skype file transfers then do google search "skype admin guide".

You can't decrypt Skype traffic so you have to use Group Policy to limit what Skype is permitted to do.
