Due to this we can longer decrypt this application, and it will be added to the SSL exclude list. Policies enforcing "whatsapp-base" will continue to function normally, but policies using "whatsapp-file-transfer" can no longer be enforced.</EM></P> <P>&nbsp;</P> <P><span class="lia-inline-image-display-wrapper lia-image-align-inline" image-alt="kiwi_0-1647257419717.png" style="width: 400px;"><img src="https://live.paloaltonetworks.com/t5/image/serverpage/image-id/39633i8D355AD8BBCB6DC2/image-size/medium?v=v2&amp;px=400" role="button" title="kiwi_0-1647257419717.png" alt="kiwi_0-1647257419717.png" /></span></P> <P>&nbsp;</P> <P>Cheers,</P> <P>-Kiwi.</P> <DIV id="ConnectiveDocSignExtentionInstalled" data-extension-version="1.0.4">&nbsp;</DIV> Mon, 14 Mar 2022 11:30:48 GMT https://live.paloaltonetworks.com/t5/general-topics/decrypting-whatsapp-traffic-and-blocking-file-uploads-possible/m-p/472829#M103247 kiwi 2022-03-14T11:30:48Z
