Exhibit A

Case File: The Wangiri Method

The 'one-ring' scam, also known as 'Wangiri,' a Japanese term meaning 'one and cut,' operates by initiating a call 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 lines that incur substantial per-minute connection fees immediately upon connection.

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

Mechanism of Financial Harm

This particular scam does not require any personal information to be shared by the recipient to cause financial harm. The act of calling the number back is the sole action necessary to generate the charge. This makes it a distinct method of illicit revenue generation.

Exhibit C

Protocol for Unrecognized Calls

The Federal Communications Commission (FCC) and Federal Trade Commission (FTC) both advise a specific course of action. If an unrecognized number rings once and disconnects, the safest response is simply not to call it back. RoboCallMeNot assists in documenting and reporting such incidents to the appropriate authorities.
