WhatsApp's New Browser Extension is Aimed at Making Web Chats More Secure

Code Verify is a new browser extension from WhatsApp parent company Meta that aims to improve the security of WhatsApp's web version, the company has announced. From a report: The extension works by verifying that the contents of WhatsApp's web version haven't been tampered with. The aim is to make it a lot more difficult for a would-be attacker to compromise data or the privacy of WhatsApp's end-to-end encrypted messages when using the browser-based version of the service. The extension follows the launch of WhatsApp's multi-device beta last year. This aims to make using the messaging service from devices other than your primary phone easier and more seamless. Since the feature's launch, WhatsApp says it's seen an increase in people accessing its service through web browsers, which present new security challenges compared to an app. There's nothing particularly new about the security methods underpinning Code Verify. Ultimately it's just comparing a hash of the code running in your browser, with a hash held by trusted third-party Cloudflare.
