Exhibit A

Case File: The Wangiri Method

The 'one-ring' scam, also known as 'Wangiri' (Japanese for 'one and cut'), operates by calling a number once and disconnecting before it can be answered. The objective is to prompt the recipient to call back out of curiosity. These callback numbers are frequently international premium-rate numbers that impose significant per-minute connection fees from the moment the call connects.

1 ring is all it takes to trigger a Wangiri callback scam — the call never even needs to connect
Exhibit B

Understanding the Financial Mechanism

This particular scam requires no personal information to be shared to cause financial harm. The financial impact is generated by the callback itself. The moment the connection is made, charges begin to accrue.

Exhibit C

Recommended Course of Action

The FCC and FTC both advise that if an unrecognized number rings once and disconnects, the safest response is simply not to call it back. Should you encounter such an incident, RoboCallMeNot allows for one-tap logging of the call. This action contributes to a broader understanding of these scam attempts.
