WhatsApp has integrated Rust to improve security in its media handling, protecting users from potential malware threats. This upgrade follows lessons learned from past vulnerabilities, enabling faster and safer media sharing across billions of devices.

WhatsApp has launched a new feature called Strict Account Settings, which allows users to enhance their privacy with a single toggle. This mode restricts various functionalities, making users less visible and enabling stronger security measures. Additionally, Meta has replaced an old media-handling library with a new one built in Rust for better security.
