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.
Feature rollout from a major platform (Meta) improves fraud detection and ad/content quality, which affects advertiser trust, platform safety, and enforcement metrics across large social channels.

Meta Takes Down 150,000 Scam Accounts in Southeast Asia
Meta, together with the Thai police and an international coalition, disabled more than 150,000 user accounts tied to professional scam farms in Southeast Asia during a Joint Disruption Week operation that resulted in 21 arrests. The takedown targeted organized networks operating in Myanmar, Cambodia and Laos that run crypto fraud, romance scams and identity theft; similar enforcement removed about 59,000 accounts in December 2024. Meta warned that scammers increasingly use generative AI to build credible digital identities and multilingual scripts to tailor attacks toward high‑value victims. The action relied on expanded cross‑border information sharing between Meta and law enforcement in multiple countries. Meta also rolled out new safety features across Facebook, WhatsApp and Messenger — including friend‑request warnings, link/device‑link alerts and an AI tool to scan conversations for known scam patterns.
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.
Meta Launches 24/7 AI Support for Instagram and Facebook
Meta has rolled out the Meta AI Support Assistant globally for Instagram and Facebook, embedding it in iOS and Android apps and in desktop help centers to provide 24/7 assistance for account, password and content issues. The assistant can answer queries and—when requested—perform actions such as password resets, reports and settings changes; chats must be initiated by the user. The rollout includes general support in all languages supported by the platforms, while some login-help features are initially limited to certain cases in the US and Canada. Meta also announced expanded AI-driven content enforcement systems that, in tests, detected thousands of previously missed fraud attempts daily, reduced impersonation reports by over 80%, doubled detection of adult sexual harassment violations while lowering error rates by over 60%, and cut views of fraudulent ads by 7%.
