WhatsApp Rolls Out Lockdown Security for High-Risk Users After Spyware Attacks
In early 2026, WhatsApp introduced a new 'Strict Account Settings' feature to defend high-risk users such as journalists and public figures against highly targeted spyware attacks. This rollout followed a series of incidents in recent years where advanced zero-click exploits—many attributed to government-linked actors—were used to deploy spyware like NSO Group’s Pegasus and Paragon Graphite onto users’ devices via messaging platforms. Exploits leveraged zero-day vulnerabilities in WhatsApp’s iOS and macOS clients, enabling attackers to compromise devices without user interaction, raising severe risks to privacy and personal safety for individuals facing nation-state targeting. This event is particularly relevant as threat actors increasingly adopt sophisticated, zero-click methods to compromise high-value targets. Security and privacy expectations for messaging apps are under heightened scrutiny, with regulators and civil society urging greater protections and rapid incident response to curtail such threats.
