Spyware and Adware

Spyware secretly gathers confidential information about the mobile user and then relays this data to a third party. In some cases these may be advertisers or marketing data firms, which is why spyware is sometimes referred to as “adware”. It is typically installed without user consent by disguising itself as a legitimate app (say, a simple game) or by infecting its payload on a legitimate app. Spyware uses the victim’s mobile connection to relay personal information such as contacts, location, messaging habits, browser history and user preferences or downloads. Spyware that gathers device information such as OS version, product ID, International Mobile Equipment Identitiy (IMEI) number, and International Mobile Subscriber Identity (IMSI) number can be used for future attacks.

Trojans and Viruses

Mobile Trojans infect user devices by attaching themselves to seemingly harmless or legitimate programs, are installed with the app and then carry out malicious actions. Such programs have been known to hijack the browser, cause the device to automatically send unauthorized premium rate texts, or capture user login information from other apps such as mobile banking. Trojans are closely related to mobile viruses, which can become installed on the device any number of ways and cause effects that range from simply annoying to highly-destructive and irreparable. Malicious parties can potentially use mobile viruses to root the device and gain access to files and flash memory.
