When it comes to Mac hacking, there are few security experts more dangerous than Charlie Miller, who can hack a Mac in mere seconds. Luckily, Miller only uses his hacking powers for the forces of good, so his hacks often lead to more secure systems for you and me.
Let’s hope that’s the case for the latest vulnerability Miller identified for the iOS platform. He has discovered a huge bug in iOS that allows malicious devs to write innocuous looking apps that slip by the App Store review process, only to phone home to a remote computer and repurpose all of iOS’s normal functions for malicious ends.
Miller proved the concept of his hack with an app called Instastock. Although Instastock appeared to be just a stock ticker, it actually phoned home to Miller’s house in St. Louis, where it downloaded new commands that allowed him to do things like read a user’s photos, contacts or emails, make the phone vibrate or even ring. Apple actually approved the app for distribution without raising an eyebrow?
Why didn’t Apple catch this stuff in the App Store review process? It’s simple: the commands to do all this malicious stuff didn’t actually exist in the software before it dialed into Miller’s home computer from the iPhone on which it was installed. Once it phoned home, it downloaded all the commands that would have normally triggered Apple’s clampdown procedures.
Miller intends on showing off his Instastock app and bug at next week’s SysCan conference in Taiwan. Presumably, Apple will fix this bug extremely quickly, but in the mean time, they have made no comment. You can read more about Miller’s hack here..
