A spyware called FinSpy, designed to help Law Enforcement and Intelligence Agencies to remotely monitor mobile phones and tablet devices, was used to determine whether various mobile platforms could withstand snooping attempts on phone calls, contacts, and other data.
The result showed that the spyware was able to break into all versions of Android (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.
But the spyware was unable to bully Apple iOS. However, the iOS was also found vulnerable but only in 'jailbroken' mode, CNET reported.
According to the researchers, iOS versions 4.3.x, 5.x, 6.x, and 7.0.x are vulnerable to FinSpy but an untethered jailbreak is required.
