The ToTok app (Breej Holding Ltd) has been reversed engineered and it has been discovered it is a deception. The app is nothing but spyware.
The app is widely used in the United Arab Emirates (UAE). In fact recently it was the #1 “trending” app in Dubai.
The app has been discovered to be uploading the entire address book to a third party server. The result of sharing the address book is very concerning and the prospect for black op agents is obvious.
So far the open source Signal has been safe as it offers end to end safe communications.
