In response to the growing threat of cyberattacks and spyware, Meta's messaging app WhatsApp...AnnounceA new feature called "Strict Account Settings" has been introduced.
This function is similar toApple's "Lock Mode"Designed specifically for high-risk groups such as journalists, activists, and public figures, it activates a series of defense mechanisms with a single click to block potential malicious attacks.
This feature is expected to be rolled out to users worldwide in the coming weeks.
Sacrificing convenience for security: Three major protection mechanisms
Enabling "Strict Account Settings" will restrict the WhatsApp user experience to a higher level of security. This primarily includes the following three protective measures:
• Blocking unfamiliar attachments:Automatically blocks images, videos, or files sent from "unknown contacts." This effectively prevents hackers from implanting viruses through malicious files.
• Disabled link preview:When sending or receiving links, webpage thumbnails and titles are not automatically generated. This prevents hackers from obtaining user IP addresses or triggering vulnerabilities through malicious links.
• Silent incoming calls from unknown numbers:Automatically mute calls from unknown numbers. This is not only to prevent harassment, but also to guard against "zero-click" attacks that exploit call protocols.
Targeting high-risk groups may not be necessary for the average person.
WhatsApp emphasizes that for the vast majority of ordinary users, the existing end-to-end encryption is secure enough and there is no need to enable this mode.
This new feature is primarily designed to protect against "highly sophisticated cyberattacks" (such as NSO Group's Pegasus spyware), which typically target specific individuals for surveillance. This follows Apple's Lockout Mode in 2022 and Android's Advanced Protection Mode last year, marking another instance of a tech company strengthening its cybersecurity defenses for high-risk users.
