Refile Fraud

In telecom networks, Refile Fraud is the manipulation of the calling party number or routing information so that traffic from a high-rate origin appears to come from a low-rate origin, allowing the carrier to pay lower termination charges while still delivering the call. It distorts settlement between operators.

Refile Fraud in context

Roaming and interconnect are where two operators exchange signaling and user-plane traffic. Trust boundaries here are the primary attack surface for location tracking, SMS interception and fraud, which is why GSMA now mandates SEPP with PRINS on 5G interconnect.

Telecom threats range from opportunistic SMS phishing and SIM swap to nation-state grade location tracking. The common thread is that most attacks exploit the inherited trust model of legacy signaling protocols.

To place Refile Fraud in the wider telecom-security picture, review Call Spoofing, Artificial Traffic Inflation, CLI Spoofing, FASG, Flash Call Fraud and ISUP — each entry cross-references back to this page so you can walk the topic in either direction.
