Apple's privacy tool, designed to mask users' actual email addresses, contains a flaw that undermines its core value proposition—attackers can reverse-engineer the real address from the masked one. This matters because Hide My Email is heavily marketed as a privacy feature across Apple's ecosystem, and the vulnerability forces users to choose between convenience (masked emails) and genuine anonymity, eroding trust in Apple's privacy claims at a moment when consumer data protection is becoming table-stakes for device makers. Masking services are only useful if they actually work; a broken privacy feature is functionally worthless and creates liability for anyone relying on it.
