Cybersecurity researchers have discovered a malicious Google Chrome extension that’s designed to steal data associated with Meta Business Suite and Facebook Business Manager.
The extension, named CL Suite by @CLMasters (ID: jkphinfhmfkckkcnifhjiplhfoiefffl), is marketed as a way to scrape Meta Business Suite data, remove verification pop-ups, and generate two-factor authentication (2FA) codes. The extension has 33 users as of writing. It was first uploaded to the Chrome Web Store on March 1, 2025.
However, the browser add-on also exfiltrates TOTP codes for Facebook and Meta Business accounts, Business Manager contact lists, and analytics data to infrastructure controlled by the threat actor, Socket said.
