How Device Verification protects your WhatsApp account

What this post added

Introduced Device Verification for WhatsApp, a new security feature to prevent account takeover attacks facilitated by malware. This feature leverages a security-token, nonce, and authentication-challenge to verify client connections to WhatsApp servers, blocking connections originating from outside the user's device that attempt to impersonate the user by stealing authentication keys. This protects against threats from unofficial WhatsApp clients containing malware.
