App stores are sites where users browse, download, and buy computing programs or "apps", mostly for mobile devices. Though Apple claims copyright to the phrase "App Store," many still refer to it when discussing apps across operating systems and brands. Device manufacturers and OS developers have native app stores built into their devices. These include Google Play, Blackberry App World, Samsung Apps, and iOS App Store. Third party app stores also exist for users who seek specific apps not available on native app stores. GetJar, MobiHand, and Handango belong to this category. The mobile app market offer apps free, on trial, or for a fee. Cybercriminals leverage this by tricking users to download bogus apps that steal credential data off mobile devices.
