We found a wave of websites posing as Calendly booking pages for job interviews at Meta. Visitors pick a slot for a 30-minute phone call with a recruiter, fill in their details, and pass what looks like a CAPTCHA. Then the page asks them to log in to Facebook. The interview is fake. The pages are designed to steal the visitor’s Facebook login details, including the two-factor authentication (2FA) codes meant to protect the account. Visitors are then asked to sign in to their Google account too,…
