Fraud Types
A one-ring scam in which fraudsters place brief calls from premium international numbers so that curious victims call back at high cost.
Wangiri — Japanese for 'one ring and cut' — relies on missed-call curiosity. The fraudster blasts millions of one-second calls, then profits from the fraction of recipients who return the call to a revenue-share number.
A newer variant, Wangiri 2.0, targets businesses by submitting premium international numbers into web contact forms so that sales teams call them back.
You may be hit on both sides: as the terminating provider whose subscribers get hammered, and as the originating provider whose network carries the expensive callbacks.
Fraud in which criminals drive traffic to expensive international premium numbers they control and take a share of the termination revenue.
The unauthorized use of a phone system or account to place calls that someone else has to pay for, usually to expensive international destinations.
Artificially inflating call volumes to a rural or high-cost destination so the terminating provider can collect inflated access charges.
