A Major Cyber Threat Emerges with 131 Malicious Chrome Extensions Targeting WhatsApp Web
A large spamware operation released 131 modified WhatsApp Web automation extensions on the Chrome Web Store. These copies use the same code and backend setup. They insert scripts into web.whatsapp.com to send bulk messages and avoid spam controls. Most were aimed at users in Brazil and uploaded by a few developers through a white-label setup.

The 131 Chrome extensions reuse one codebase and a reseller model to keep clones online and to evade simple takedowns. Defenders should restrict extensions, audit browser profiles, and monitor for new extension artifacts and unusual browser flags.
