Apple’s ‘Hide My Email’ Reportedly Exposes Your Real Email Address

Apple’s ‘Hide My Email’ feature, designed to protect user privacy by generating anonymous email aliases, has a security flaw that can expose users’ real email addresses to malicious actors. This vulnerability, reported by 404 Media, has been known to Apple since June 2025 and is still unpatched as of July 2026, raising concerns about the effectiveness of the privacy tool.

According to reports, bad actors can exploit the ‘Hide My Email’ feature by using free, publicly accessible people-search sites to discover the real email addresses behind aliases. The flaw was tested by Lifehacker and other researchers, who found that within minutes of receiving an alias, they could retrieve the actual email address associated with it. This vulnerability affects users who rely on ‘Hide My Email’ for privacy, especially when signing up for third-party services or online accounts.

Apple responded to the reports by confirming it was aware of the issue since June 2025 and had been investigating it. The company announced a patch in March 2026 but, according to recent reports, the flaw persists as of July 2026. Apple is reportedly continuing its investigation, with some sources indicating that a fix may still be in development.

Potential Privacy Risks for ‘Hide My Email’ Users

This flaw undermines the primary purpose of ‘Hide My Email,’ which is to protect user identities and prevent exposure of personal contact information. If malicious actors can uncover real addresses, it could lead to targeted phishing, spam, or identity theft. The issue also questions the reliability of Apple’s privacy claims, especially as the company prepares to change the alias domain, which could further reduce the feature’s effectiveness.

Background and Previous Concerns About ‘Hide My Email’

‘Hide My Email’ was introduced as part of Apple’s broader privacy initiatives, allowing users to generate random email addresses that forward to their real inboxes. The feature is widely used by privacy-conscious users to avoid sharing personal email addresses with untrusted services. In recent weeks, reports emerged that Apple plans to change the domain of these aliases from @icloud.com to @private.icloud.com, which could make it easier for automated systems to identify aliases and reduce their anonymity. The vulnerability’s discovery adds to growing concerns about the feature’s robustness and Apple’s handling of privacy protections.
