WhatsApp is rolling out Strict Account Settings, a new security feature designed to protect users vulnerable to sophisticated cyberattacks. This is similar to Apple's Lockdown Mode, targeting journalists, activists, and public figures. The feature locks down account options to their most restrictive settings, minimizing potential threats from spyware and malicious files.

For example, the new settings automatically block attachments and media from unknown senders. Other impacted areas include two-step verification, messaging, and profile visibility. Users can find the settings under Privacy and Advanced. The rollout will be gradual, depending on location. WhatsApp Web users won't have access, it's only available on your primary device.

Simultaneously, WhatsApp has transitioned parts of its codebase to Rust, a memory-safe programming language. This change improves the protection of photos, videos, and messages against spyware. This move reflects a broader trend in the tech industry. Companies are employing Rust to enhance security and improve software performance.

This update is especially timely, given the increasing sophistication of digital threats. By offering more robust security features, WhatsApp aims to provide better protection for at-risk individuals. The integration of Rust also underscores the platform's commitment to proactive security measures. It is worth watching if other messaging apps follow suit.
