Researchers found a significant security flaw in WhatsApp that allowed hackers to easily access phone numbers and some profile information for all 3.5 billion users. Despite being warned about the issue since 2017, Meta only implemented a fix in October 2023. Users are urged to review their privacy settings to protect their information.

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.

Meta has enhanced scam protection features on its messaging platforms, WhatsApp and Messenger, to combat increasing fraudulent activities. These updates aim to bolster user security and provide better tools for identifying and reporting scams. The initiative reflects Meta's commitment to creating a safer online environment for its users.
