4. There Are More Than 500 Third-Party Application Stores
Juniper said its researchers identified more than 500 third-party application stores hosting mobile malware. Many stores are based in China and Russia, locations that are infamous for malware and financially motivated cybercrime. Android device owners can easily use them to download apps, but the stores also serve jailbroken iOS devices. Juniper estimates about several million iPhone and iPads are manipulated to side-load apps.
