131 Chrome Extensions Hijack WhatsApp Web for Spam
🔍 Cybersecurity researchers uncovered a coordinated operation that used 131 rebranded Chrome extensions—about 20,905 active users—to inject automation code into WhatsApp Web and conduct large-scale spam campaigns targeting Brazilian users. Socket found the add-ons share a common codebase, design patterns, and infrastructure and are primarily published under WL Extensão variants. The extensions pose a high spam risk by automating bulk outreach and scheduling to evade WhatsApp rate limits and violate Chrome Web Store policies.
