Mobile security firm Appthority published an interesting report that reveals which mobile apps, both Android and iOS, are most frequently blacklisted by enterprises. According to the company, iOS apps are mainly blacklisted because many of them leak data. Whatsapp is the most commonly blacklisted iOS app because it sends information from the devices address book to a remote server. Android apps have been mostly blacklisted for data leakage or because they exhibit malicious behavior. For 86.7% of Android apps the connections are to a server located in the United States.”]
