WhatsApp has launched a new high-security mode called "Strict Account Settings," providing users with enhanced defenses against sophisticated cyber threats. This feature, introduced on January 27, 2026, allows one-click activation and builds on the platform's existing end-to-end encryption. It targets high-risk individuals like journalists and public figures facing advanced attacks, marking WhatsApp as the third major tech firm to offer such protections after Apple's Lockdown Mode and Google's Advanced Protection.
The mode activates multiple safeguards simultaneously through a simple toggle in WhatsApp settings under Privacy > Advanced. It blocks media files and attachments from unknown senders, preventing potential malware delivery via images or documents. Link previews—thumbnails that appear for shared URLs—are disabled to eliminate risks from embedded tracking or exploits, while calls from unknown numbers are automatically silenced, appearing only in missed calls.
These measures address common attack vectors identified in cyber surveillance campaigns. For instance, malicious attachments and link previews have been exploited in spyware incidents targeting activists and reporters. By muting unknown calls, the feature reduces social engineering attempts like vishing scams, where attackers impersonate contacts to extract information. WhatsApp's blog emphasizes that while everyday users benefit from standard encryption, this mode offers "extreme safeguards" for rare, high-sophistication threats.
Similar to competitors' offerings, robust account settings trades convenience for security, limiting app functionality for greater protection. Apple's Lockdown Mode, available since 2022, restricts attachments and browser features, while Google's Android version blocks risky app downloads. Cybersecurity experts have welcomed WhatsApp's step, calling it a "very welcome development" for civil society defenders. The rollout is global on iOS and Android, with full availability expected in coming weeks.
As cyber threats evolve with AI-driven attacks and state-sponsored hacking, features like this empower users to customize defenses. High-risk professionals can now layer protections without switching apps, fostering safer digital communication. However, Meta advises reviewing settings post-activation, as it may block legitimate interactions from new contacts. This move aligns with rising demands for privacy amid global data scandals.
