WhatsApp Unveils Lockdown Feature to Shield High-Risk Users from Hackers
Meta has launched a new feature for WhatsApp, aimed at enhancing security for high-risk users. This update, called “Strict Account Settings,” specifically targets individuals such as journalists and public figures who face sophisticated cyber threats, including spyware attacks.
What is the WhatsApp Lockdown Feature?
The “Strict Account Settings” feature extends the existing end-to-end encryption by implementing stricter protective measures. This functionality can only be enabled on the user’s primary device. To activate this feature, users should navigate to Settings, then Privacy, and select Advanced.
Key Security Enhancements
Upon activation, users will experience several protective changes:
- Automatic two-step verification
- Blocking media and attachments from unknown senders
- Silencing calls from unknown contacts
- Turning off link previews to reduce phishing risks
- Locking access to last seen and online status
- Restricting visibility of profile photo, About details, and profile links
WhatsApp emphasizes that this feature is intended for users who believe they may be targeted by sophisticated cyber attacks. It is not recommended for everyone, as most people are unlikely to experience such threats.
Background of Security Concerns
This announcement follows documented cases where journalists, activists, and politicians became victims of spyware attacks by groups like the NSO Group. Hackers have utilized zero-click exploits to access iOS and Android devices without user interaction, leading to widespread vulnerabilities.
Recent Vulnerabilities and Legal Actions
In August, WhatsApp addressed a zero-day vulnerability in its iOS and macOS platforms. This flaw was linked to previous targeted attacks. Additionally, legal proceedings revealed that the NSO Group continued to deploy zero-day exploits even amidst ongoing lawsuits by WhatsApp.
In 2025, the company faced a significant penalty of $167 million for attacks that affected 1,400 WhatsApp users in 2019.
Comparison to Apple’s Lockdown Mode
Apple introduced its own Lockdown Mode in July 2022, designed to protect high-risk individuals from targeted spyware attacks on iOS, iPadOS, and macOS systems. This mode restricts various functionalities to minimize vulnerability to highly targeted mercenary spyware.
As Meta rolls out the “Strict Account Settings” feature, it highlights its commitment to safeguarding user privacy and reinforces the importance of security in today’s digital landscape.
