Meta announced a robust security update for WhatsApp in Brazil, aimed at tackling the growing sophistication of cyberattacks. The new feature introduces a set of measures specifically designed to protect users who are more vulnerable to digital espionage, such as activists, journalists, and public figures.
The information was disclosed by Meta itself, which detailed that the new security package changes how the app processes received files, creating a more restrictive and preventive environment against digital threats. The initiative is part of a global strategy to reduce risks associated with sending malicious content via messaging apps.
The main highlight of the update is the implementation of the feature called Strict Account Settings. When manually activated by the user, this function prevents photos, videos, and documents sent by unknown numbers from being automatically downloaded to the device.
The measure aims to neutralize the spread of malware that disguises itself as harmless files, a common practice in targeted attacks. With the new system, no suspicious content is saved to the device without a conscious action from the user, significantly reducing the chances of infection by malicious software. Another important advancement is in the technological base of the tool. WhatsApp now uses the Rust programming language for media processing. Recognized in the tech sector for its ability to prevent memory errors—flaws often exploited by hackers—the adoption of Rust makes the app’s infrastructure more resistant to invasions and critical exploits.
Additionally, the messenger now features a background verification system capable of identifying files known as “chameleons”, which simulate being videos or images but hide malicious code. This analysis occurs even before the attachment is executed and works independently of the device’s operating system, whether Android or iOS, even if it’s not fully updated.
According to Meta, the combination of these protection layers enhances WhatsApp’s ability to detect threats before they cause damage, reinforcing the security of users’ personal data and communications.
The update is being rolled out gradually to users in Brazil. Those who already have access to the feature can enable it by going to the Settings menu, entering the Privacy tab, and then selecting Advanced Settings, where they can enable the additional protections.
The company’s expectation is that the new security mode will help make WhatsApp a safer environment amid the rise in digital scams, cyber espionage, and targeted attacks, which are becoming increasingly frequent and sophisticated.
