Meta rolls out new scam detection tools for Facebook, WhatsApp and Messenger

As online scams become increasingly sophisticated, Meta is introducing a new set of tools aimed at helping users detect fraud before they fall victim to it. The company has announced fresh scam detection features for Facebook, WhatsApp and Messenger that will alert users to suspicious activity and potentially risky interactions.

According to Meta, the tools are designed to flag unusual behaviour early, giving users a chance to pause and reconsider before responding to suspicious friend requests, device-linking attempts or scam messages.

The company said these measures are necessary because online fraudsters constantly evolve their tactics and often attempt to operate undetected.

New warnings aim to stop scams early

One of the key updates focuses on WhatsApp’s device-linking feature. Users will now receive alerts if the system detects unusual behavioural signals when someone attempts to link their account to another device.

The warning message will show where the request is coming from, allowing users to assess whether it appears legitimate before approving it.

Meta explained that scammers frequently attempt to trick victims into sharing device-linking codes through elaborate social engineering tactics.

“For example, they may pose as a talent competition asking you to cast your vote by going to a website and entering your phone number, followed by a device linking code on your WhatsApp,” the company said. “They may also try to trick you into scanning a QR code under false pretenses, which would then link the scammer’s device to your account.”

The goal of the alert system is to interrupt these schemes before they succeed, particularly when scammers attempt to gain control of a victim’s account.

Meta is also testing new alerts on Facebook to flag suspicious friend requests. These notifications may appear when a user receives or sends a request to an account that shows unusual signals, such as having very few mutual connections or being located in a different country.

The company hopes the warnings will encourage users to think carefully before accepting requests from unfamiliar profiles.

Meanwhile, the company is expanding advanced scam detection tools on Messenger to more countries. These systems analyse conversations for patterns that resemble common scams, including fraudulent job offers or requests for sensitive information.

If suspicious behaviour is detected in chats with a new contact, users may be prompted to share recent messages for an AI-based review. Should the system identify potential fraud, it will encourage the user to report or block the account involved.

The rollout comes shortly after Meta participated in a large international crackdown on organised scam networks operating in Southeast Asia.

The company said it removed more than 1,50,000 accounts linked to scam centres across Facebook and Instagram following a coordinated law enforcement operation.

Nearly 4,900 of those accounts were identified with intelligence provided by the Singapore Police Force. The operation, known as Joint Disruption Week, was led by the Royal Thai Police Anti-Cyber Scam Center in collaboration with the Federal Bureau of Investigation and the US Department of Justice’s Scam Center Strike Force.

Authorities in Thailand arrested 21 individuals suspected of involvement in online scam activities during the operation.

By combining new technology tools with international enforcement efforts, Meta says it aims to make its platforms more resilient against the growing threat of digital fraud.
