WhatsApp is testing a new warning for scam messages

Meta is rolling out Scam Alert, an optional beta feature for WhatsApp that uses an on-device machine-learning model to flag likely scam messages from users who are not in a contact's list. The alert examines incoming messages for patterns associated with fraud but only displays a warning banner rather than blocking communication. Users are also advised to enable two-step verification and regularly review their linked devices for account security.
