Microsoft 365 users hit by phishing scheme posing as RingCentral emails
Security researchers at ZeroBEC say a phishing-as-a-service platform called Greatness has been used to spoof RingCentral emails and lure Microsoft 365 users to fake login pages that capture MFA-approved authentication tokens. Greatness is also reported to target iCloud, Yahoo, and Google Workspace accounts. The service is advertised on Telegram for $289 per month, per BleepingComputer.
