Manufacturer's Backdoor Found On Popular Chinese Android Smartphone

Trailrunner7 writes that researchers at Palo Alto Networks have found a backdoor in Android devices sold by Coolpad. "A popular Android smartphone sold primarily in China and Taiwan but also available worldwide, contains a backdoor from the manufacturer that is being used to push pop-up advertisements and install apps without users' consent. The Coolpad devices, however, are ripe for much more malicious abuse, researchers at Palo Alto Networks said today, especially after the discovery of a vulnerability in the backend management interface that exposed the backdoor's control system. Ryan Olson, intelligence director at Palo Alto, said the CoolReaper backdoor not only connects to a number of command and control servers, but is also capable of downloading, installing and activating any Android application without the user's permission. It also sends phony over-the-air updates to devices that instead install applications without notifying the user. The backdoor can also be used to dial phone numbers, send SMS and MMS messages, and upload device and usage information to Coolpad."

Some things would be detectable, some wouldn't, some would be illegal, most would be pointless to do for Apple and would be damaging to business if found out, which is a very good reason not to do it.

Well, technically you asked for it, but nothing needs to appear on your iOS device at that moment to ask you. Quite obviously, Apple _can_ install software on your iPhone, because that's what they have to do when you purchase software. Being asked by you to do it is just a small detail. In reality, Apple doesn't install software without asking you.

      Apple _can_ remove software without asking you, and would probably do that to remove malware, if it decides that removing the malware without your explicit permission is better for the customer than not removing it.
