A privacy flaw in Apple’s Hide My Email feature means that your real email address can be discovered. A security researcher said that tests found 100% of generated addresses allowed an attacker to reveal the real email associated with the Apple account.

Tyler Murphy said that he discovered and reported the issue to Apple more than a year ago, but it still hasn’t been fixed, and he has now made the decision to go public …

404 Media said it has verified the issue.

“Apple Hide My Email is leaking email addresses that are supposed to be hidden. We reported the issue and replication instructions to Apple over a year ago. We don’t know why it hasn’t been fixed, but we don’t feel comfortable waiting any longer. Hide My Email users deserve to know that it may be possible for attackers to discover their hidden email addresses,” Tyler Murphy, the co-founder of EasyOptOuts, which discovered and reported the issue to Apple, told 404 Media.

404 Media is not revealing the exact details of the vulnerability because it can still be exploited as of Monday, when 404 Media verified the issue with one of our own hidden email addresses.
