WhatsApp Launches Enhanced Security Mode to Protect Users from Targeted Attacks

Amid increasing scrutiny over privacy and account security, WhatsApp, owned by Meta, has introduced a new "Strict Account Settings" feature, a high-security mode designed to offer users enhanced protection against account theft and targeted attacks. This function is particularly aimed at high-risk users, such as journalists, activists, and public figures, who are more likely to face sophisticated hacking attempts. While WhatsApp already employs end-to-end encryption to safeguard messages, this latest mode restricts interactions with unknown contacts, blocks unsolicited files and links, and notifies users when encryption keys are altered.

The high-security mode is optional but intended to provide robust protection for those who need it most. When activated, it limits several default behaviors within WhatsApp that could be exploited maliciously. Files from contacts not in the recipient's list, such as photos, videos, and documents, are automatically blocked.

Even unknown contacts cannot send link previews, minimizing the risk of accidentally opening harmful URLs. Calls from strangers are muted to prevent phone-based phishing. Additionally, this setting enforces two-step verification and alerts users when a contact's encryption key is updated. Users can enable Strict Account Settings by navigating to Settings, then selecting Privacy, and finally choosing Advanced.

"We are also rolling out a programming language called Rust behind the scenes to help protect your photos, videos, and messages from threats like spyware, so you can share and chat with confidence," the company noted.

This move aligns with the latest trend among tech companies offering "extreme security" modes for high-risk individuals. For instance, Apple introduced Lockdown Mode in 2022 for iPhone and Mac users, which significantly restricts device functionality to prevent highly targeted spyware attacks. Similarly, Google has launched Advanced Protection for Android, limiting app installations and strengthening system permissions. WhatsApp's high-security mode builds on these approaches but focuses on protecting messages and calls.

This timing is particularly crucial for the platform, as a recent class-action lawsuit in the U.S. alleges that Meta can access WhatsApp messages despite the company's promises of end-to-end encryption. Even Elon Musk recently publicly questioned WhatsApp's security claims, stating, 'WhatsApp is not secure.'
