Sinch is a global telecommunications API provider that supplies enterprise SMS messaging, virtual phone numbers, and voice trunks. While legitimate companies (e.g. Uber, delivery apps) use Sinch for two-factor authentication codes, cybercriminals purchase Sinch virtual numbers through reseller aggregators to send mass smishing messages claiming your bank account or package delivery is suspended.
