FCM Message Notifications
A couple of our users received random notifications on the Teams mobile app this morning. The notification states "FCM Message". Anyone have an idea what's going on?
I received 5 notifications this morning "FCM Messages Test Notifications!!!!"
seems it is related to an exploit lets hope that Microsoft or Google plug it soon, otherwise I'll be uninstalling the Teams app on my phone.
I have also received these messages a little under an hour ago and this problem seems be on a global level.
Seems to me like they should change their token (API key) so that it isn't as easily exploited.
This article was published 17th August 2020 and as far as I can tell is the base idea for these exploits:

Let us hope that this will be fixed with an update to the apps.
