Wangiri telecom fraud activity reported in Canada

The Canadian Anti-Fraud Centre has reported a recent wave of Wangiri telecom fraud calls to Canadian telephone subscribers in the Montreal area. Here’s what’s happening.

In the Wangiri fraud attack profile, the fraudster programs their auto dialer to ring each telephone call once, then hang up before the called party can answer. The caller ID is a high-cost overseas number. The fraudster hopes that victims will be tempted to return the missed call.

When a victim does return the call, their telephone account will be charged at a very expensive rate.

The countries associated with the calling numbers used in this wave of Wangiri attacks have included the Congo, Argentina, El Salvador, and the Central African Republic.

Several Fido telephone service customers have reported receiving these Wangiri calls.

Consumers are encouraged not to call back one-ring calls from overseas numbers that they don’t recognize.
