Security Researcher Reveals iOS Security Flaw, Gets Developer License Revoked
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.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:
The researcher soon dug up a bug that allowed him to expand that code-running exception to any application he’d like.
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.
