It is important to remember that with this rule, messages will work normally, but the download and upload of files will not, therefore, the images of the users/groups are not displayed.
To block file upload via whatsapp you need:ġ- Remove the SSL interception of the whatsapp application and domain Ģ- Create a policy in a web access layer ģ- Set the destination for the domains listed below(Recomended to create a List): So in order to update this KB a bit I created a rule that is very similar to the KB, but with updated domains.
Step 3: You have to choose who can change the group information including name, icon and description. Step 2: Tap on the option Edit group info. Here’s what you can do: Step 1: Go to WhatsApp Group Settings as demonstrated earlier. Initially, it is impossible to intercept whatsapp conversations and functions via proxy, it uses end-to-end encryption which the proxy cannot intercept, but it is possible, from the domains and requests that Whatsapp web makes, to block or allow a request pattern, in the Broadcom documentation it is instructed to create a CPL that blocks the domain "", but when searching a little, this domain is no longer used in sending files, now, when sending a Post or Get of files, is used the common domain of Whatsapp but with a "subfolder" mmg. Similarly, you can limit non-admins from changing the group information such as name and icon. I recently came across a request from a customer in which it was necessary to allow the use of Whatsapp, but block any attempt to send files, only the messages were released, I even saw that Broadcom created a documentation about it in 2019, but the documentation did not works as it should, so I created a more updated version of the domains and wanted to pass it on to you in case anyone is interested in replicating. Hi everyone, I hope everyone in the community is doing well.
