Is that a Spy in Your Pocket?
A leaked Gamma Group study indicates which smartphones are the easiest to hack with FinSpy spyware:
Among the major mobile platforms cited in a chart in the document, all of them were susceptible to FinSpy. The spyware was able to bully its way into Android (all versions from 2.x.x to 4.4.x), BlackBerry (versions 5.x, 6.x., and 7.x), Symbian, and Windows Mobile 6.1 and 6.5 (Windows Phone 8 is not yet supported by the software).
And what of iOS? Apple's mobile OS did make the list but only in jailbroken mode.
And what can FinSpy do? Read:
FinSpy is "designed to help Law Enforcement and Intelligence Agencies to remotely monitor mobile phones and tablet devices."
FinSpy can gain full access to phone calls, text messages, the address book, and even the microphone via silent phone calls. It can also trace a device to determine its location. Used by law enforcement and government agencies, FinSpy has earned a reputation for itself as a powerful but controversial tool for sneaking into mobile devices.
If you need Android's openness, there's probably no better alternative. But the vast majority of Android buyers don't need open -- they aren't even really smartphone users. They buy Android because it's inexpensive and it's good enough and it works on their carrier. But what those buyers really are is feature phone users. They'd probably be better off, and they'd certainly be more secure, sticking with simpler Symbian devices.
