Fraudulent traffic types

Wangiri calls where end users enticed into calling fraudulent premium-rate numbers.
Machine generated calling identifying vaulnerable phone systems.
Hacked PBX systems re-routing of phone calls or mass-calling premium-rate numbers.

Non-roaming traffic where the calling number belongs to the same country as the called number.

Fraudulent calls can be identified by identifying high volume calls from number series with specific characteristics including:

  • Known fraudulent number series
  • Terminating in known fraudulent number series
  • From number series marked as unassigned,
  • Premium-rate numbers
  • Roaming number

STINGA Probes collect voice call signalling directly from their international voice network, generating Call Detail Records (CDRS) providing a complete overview of the voice traffic across the network and quickly identifying traffic matching these patterns.

The STINGA Fraud Solution quickly identifies calls that match fraudulent traffic profiles quickly, and generate alerts to escalate these to your anti-fraud team for urgent investigation.
