WhatsApp has introduced Strict Account Settings, a lockdown-style security feature designed to protect users from highly sophisticated cyber-attacks.
The new privacy feature is specifically tailored for individuals who may be targets of advanced threats, including journalists, activists, and public figures who face elevated cybersecurity risks.
The instant messaging platform, which already provides default end-to-end encryption for all personal messages and calls, continues to build additional layers of security.
Strict Account Settings represents an extreme protection measure that locks user accounts to the most restrictive privacy configurations with just a few taps, significantly reducing the attack surface available to threat actors.
Enhanced Security Through Restrictive Settings
When enabled, Strict Account Settings automatically implements several defensive measures to shield users from sophisticated attacks.
The feature automatically blocks all attachments and media from unknown senders, preventing the distribution of malware or phishing attempts via multimedia content.
This addresses a common attack vector where threat actors send malicious files disguised as legitimate documents or images.
The lockdown feature also silences incoming calls from people not saved in the user’s contact list.
Eliminating the risk of voice-based social engineering attacks and preventing harassers or attackers from establishing direct voice communication.
Additionally, the feature restricts other settings that may limit certain app functionalities in exchange for maximum security.
Protecting High-Risk Users
WhatsApp believes that private conversations should remain as secure on digital devices as they would be in person.
For most users, the platform’s standard end-to-end encryption provides adequate protection.
However, for the small percentage of people who face rare yet sophisticated cyber threats, Strict Account Settings provides an additional security layer beyond conventional protection measures.
Journalists reporting on sensitive topics, political figures, human rights activists, and other high-profile individuals often face targeted attacks from advanced persistent threat (APT) groups or nation-state actors.
These sophisticated attackers employ techniques like zero-click exploits, spyware deployment, and social engineering to compromise accounts and access confidential communications.
Users can enable Strict Account Settings through a simple navigation path within the application. The feature is accessible by opening WhatsApp Settings, selecting privacy, and then navigating to Advanced options.
The rollout will begin in the coming weeks, gradually becoming available to all WhatsApp users globally on Android and iOS.
While the feature provides maximum security, users should understand that it may limit some app functionality and user experience aspects.
WhatsApp continues to demonstrate its commitment to user privacy and security through continuous innovation in protective features, ensuring that even those facing the most advanced cyber threats can communicate safely and confidentially.
