WhatsApp runs on-device AI to detect scams
WhatsApp is testing a new feature called Scam Alert that uses a small machine-learning model running directly on users' phones to identify potential scam messages without sending private message content to Meta. The on-device model analyzes incoming messages from unknown contacts for structural and linguistic scam indicators; warnings are shown only to the recipient and the feature is voluntary and can be disabled. Meta is rolling out Scam Alert in a limited beta, will work with security researchers to audit the system, and plans to publish model versions, checksums, and model weights so independent researchers can verify behavior. Google has previously introduced similar on-device scam detection features.
Major platform (Meta) releasing a privacy-preserving, on-device AI feature for scam detection that affects messaging security, data-handling practices, and researcher auditability for a large user base.

WhatsApp 'Scam Alert' Adds On-Device Scam Detection
WhatsApp is developing a feature called “Scam Alert” to warn users when messages from unknown contacts resemble potential scams. Discovered by WABetaInfo in the latest Android beta (version 2.26.22.2), the functionality is designed to run fully on users’ devices and remain compatible with end-to-end encryption, meaning message content would not be sent to external servers for analysis. The warning appears directly in the chat and lets users choose to block, report, or continue the conversation. Scam Alert is optional, disabled by default, not yet available to beta testers, and WhatsApp has not announced a public release date.

Meta Unveils Advanced Scam Detection for Facebook and WhatsApp
Meta announced new scam-detection features for Facebook, WhatsApp and Messenger designed to warn users before engaging with suspicious activity. Facebook is testing alerts for potentially fraudulent friend requests (signals include few mutual friends or differing country locations). WhatsApp will show device-linking warnings when behavioral signals suggest a linking request may be suspicious, including protections against QR-scan and linking-code schemes. Messenger’s advanced scam detection is being expanded to more countries and can ask users to share recent chat messages for an AI-assisted scam review when conversations show patterns associated with scams. Meta reported removing more than 159 million scam ads last year (92% removed before reports) and 10.9 million accounts across Facebook and Instagram linked to criminal scam centers.
