Security researcher Charlie Miller revealed earlier today that he had found an exploit in Apple's iOS software that allows an App to run arbitrary code. Apple generally approves all code that is submitted to the AppStore and forbids the execution of un-approved code, but Miller discovered a way to bypass this restriction. Forbes writes:
Miller became suspicious of a possible flaw in the code signing of Apple’s mobile devices with the release of iOS 4.3 early last year. ... The researcher soon dug up a bug that allowed him to expand that code-running exception to any application he’d like.
Beyond discovering the bug, Miller went a step further and actually had an App submitted to the App Store which took advantage of this bug. The App was approved and was able to perform as expected:
Using his method–and Miller has already planted a sleeper app in Apple’s App Store to demonstrate the trick–an app can phone home to a remote computer that downloads new unapproved commands onto the device and executes them at will, including stealing the user’s photos, reading contacts, making the phone vibrate or play sounds, or otherwise repurposing normal iOS app functions for malicious ends.
Shortly after the news broke, Apple revoked Miller's developer account, citing a breach of the developer agreement.
“This letter serves as notice of termination of the iOS Developer Program License Agreement…between you and Apple,” the email read. “Effective immediately.”
Miller plans to present his findings at the SysCan conference in Taiwan next week.
Bloomberg's Mark Gurman has high expectations for Apple's first foldable iPhone.
In his Power On newsletter today, he said the foldable iPhone will be "the most significant overhaul in the iPhone's history."
"iPhone 4, iPhone 6 and iPhone X were clearly a big deal, but this is a whole new design," he said.
Like Samsung's Galaxy Z Fold 7, the foldable iPhone will reportedly open up like ...
iOS 26.5 is now available for developers, and while it doesn't include any new Siri capabilities, there are some major changes for the European Union, and smaller tweaks for features available worldwide.
Suggested Places
In the Maps app, there's a new "Suggested Places" feature that recommends locations to visit based on trending places nearby and recent searches. When Apple launches ads in ...
New images of an alleged iPhone 18 Pro prototype and screen protectors have emerged from multiple sources, adding weight to earlier reports that Apple plans to significantly shrink the Dynamic Island later this year.
An X user called @earlyappleleaks recently shared an image purportedly showing a prototype iPhone 18 Pro with a noticeably smaller Dynamic Island. In the picture, the flashlight ...

Meanwhile Google is handing out bounties for stuff like this. Because why would you want to get (almost) free help from industry-leading professionals? Submitting it to the App Store probably wasn't the way to go, though.
It's one thing to find a security hole and professionally inform Apple, quite another to write an app to exploit it and announce you will tell the works how to do it in a conference in a week...
Charlie is a smart guy who makes some really stupid decisions.
Professional developers disclose issues in iOS to Apple through secure channels all the time without this media madness.
