WhatsApp Unveils New Scam Alert Feature
Medium
Summary
WhatsApp is rolling out a limited beta feature called Scam Alert, designed to identify potentially scam messages on users' devices *before* they are sent. The feature uses on-device machine learning, doesn't send message content to WhatsApp, and is backed by a complex, multi-layered verification system to ensure privacy and security. This comes alongside Signal’s new automatic key verification feature, aimed at bolstering end-to-end encryption and preventing unauthorized key swaps.
