Apple quietly built a scam detector into iOS 27, and most people have no idea it exists.
According to Engadget, the feature - known as impersonator risk detection - shipped with iOS 27 without a keynote mention or a dedicated support page. It's built to catch calls and messages that claim to come from a trusted contact or organization but don't actually match who they say they are. The tool works in the background on iPhone and iPad, flagging suspicious contact attempts before a user acts on them. Engadget's report calls it one of the update's most useful additions, despite Apple giving it almost no promotion.
Impersonation scams - fake bank reps, spoofed family emergencies, bogus customer support calls - are exactly the attacks that slip past filters built for robocalls and phishing links. Baking detection into the OS instead of a third-party app means it reaches every user by default, not just the ones who bother to install protection. That default-on reach, more than the obscure feature name, is the actual news.
Apple has a long history of shipping quiet security wins in release notes nobody reads. This looks like another one, and for once, that's a compliment.
