WhatsApp to Block Spam and Scam Calls
WhatsApp has started testing a new Scam Alert feature in its Android beta version that detects fraud attempts on the device.
WhatsApp has launched its new Scam Alert feature, developed to detect scam attempts from unknown numbers, in beta for a limited number of users. This new feature, introduced with WhatsApp beta for Android version 2.26.34.1, uses a machine learning model on the device to analyze message content locally.
This technology ensures that messages are protected without breaking the end-to-end encryption protocol, preventing any information from being sent to WhatsApp servers. Currently available only to Android beta users, this feature aims to raise the platform’s security standards to a higher level.
- WhatsApp uses a local machine learning model running on the device to detect fraudulent content.
- The new feature maintains user privacy as messages remain end-to-end encrypted.
- The Scam Alert system is disabled by default and needs to be manually activated by users.
- The system analyzes messages from unknown. numbers and instantly flags potentially risky situations.
How the Scam Alert Feature Works
The Scam Alert feature operates thanks to an algorithm that runs locally on the user’s device. When a message is received, the system compares this content to known fraudulent patterns.
If a message is flagged as suspicious, WhatsApp displays a warning message to the user. During this process, no message text, audio files, or media content is transmitted to Meta servers.
Therefore, even WhatsApp itself cannot view the content of the messages.
User Control is Fully Protected
WhatsApp ensures users have full control over this new security tool. The feature is disabled by default; Users can enable this protection through their account settings if they wish.
If the system accidentally marks a message as suspicious, users can remove the warning by marking the chat as ‘trusted’. Additionally, users can contribute to the model’s more accurate operation by sharing their last five messages with WhatsApp.
Privacy Policy is Prioritized
Meta prioritizes transparency in the development of this model. All users use the same model version, and the model’s integrity is verified with publicly available records before distribution.
IP addresses are hidden using a relay system when devices request model updates, making it impossible to track who is updating. Additionally, the Bug Bounty program is being expanded for security researchers, further supporting the system’s reliability through external controls.
Android Beta Users Can Test the Feature
Currently available to a limited number of beta users, this feature is being gradually rolled out through updates released on the Google Play Store. While it’s not yet clear when it will be available for iOS users, WhatsApp is expected to bring this feature to all platforms.
Users can check which messages the Scam Alert feature has flagged and their system history at any time via their device’s activity log.
