Apple s Hide My Email feature is a convenient privacy tool that uses disposable addresses to hide a user s true email for the sake of online anonymity. Unfortunately, new research appears to show that a bug in the feature allows users real email addresses to be unmasked.

The bug was reported by 404 Media, which says that it has tested and verified that the vulnerability exists. Tyler Murphy, the researcher who found the bug, said that he warned Apple about the problem over a year ago, and that it was unclear why the company had yet to remedy the problem. All of the attempts to exploit the bug have been successful, Murphy added.

“We don t know the full scope of the issue, but in our limited tests with volunteers, 100% of Hide My Email addresses were exploitable,” Murphy told the outlet. Details of the vulnerability haven t been publicly disclosed, for fear that it will be exploited.
