NEW YORK (AP) – Much has been made of both the benefits and dangers that come with strong encryption, especially the methods used by Apple to secure its devices. But new research shows that Apple’s security isn’t as impenetrable as both the company and its critics claim.

A team from Johns Hopkins University says it found a security bug in iMessage, the encrypted messaging platform used on Apple’s phones and other devices. The bug would allow hackers under certain circumstances to decrypt some messages.

The Johns Hopkins team is posting its paper on the Internet on Monday after Apple’s release of a patch fully fixing the bug. The team reported its findings to Apple in November.
