Switched your phone off? Hackers can still spy on you

摘要

Security experts have detected new Android malware that tricks people into thinking they have turned off their phone. When you press the 'Power off' button on your phone (see image), the malware shows a fake box designed to look like the real Android 'Power off menu. The phone then displays a black screen, and looks like it's switched off. You won't hear any sound alerts or see any notification lights. However, the phone is actually still switched on. The malware has inserted a line of code into Android's shutting-down process that lets hackers access the device remotely, theoretically allowing them to do anything they like.
