Telecom Fraud Detection Software | SIM Swap, IRSF & Subscription Fraud AI
Real-time Fraud Management System (FMS) analyzing signaling telemetry, CDR patterns, and account anomalies to stop International Revenue Share Fraud (IRSF), SIM box bypass, and account takeovers.
What is Telecom Fraud Detection Software in Telecom & Communications?
Telecom fraud detection software applies machine learning and behavioral analytics to real-time signaling (SS7, Diameter) and Call Detail Records. It detects International Revenue Share Fraud (IRSF), fraudulent SIM swapping, SIM box bypass interconnect bypass, and PBX hacking, neutralizing fraudulent calls before charges accumulate.
Core Engineering Capabilities for Modern Telecom Networks
Production-grade features designed for CSPs, MNOs, MVNOs, and telecommunications infrastructure providers.
International Revenue Share Fraud (IRSF) Defense
Identify automated dialing bursts to high-cost premium rate destination ranges and unallocated international numbering plans in real time.
Unauthorized SIM Swap Anomaly Detection
Flag high-risk SIM swap requests based on device location divergence, recent password changes, and suspicious retail employee behavior.
SIM Box & Interconnect Bypass Detection
Detect illegal GSM gateways and SIM farms terminating international traffic locally using cellular mobility metrics and IMEI analysis.
Subscription & Identity Fraud Prevention
Stop organized fraud rings opening subsidized high-end smartphone contracts using stolen identities, synthetic credentials, and mule addresses.
PBX Hacking & Wangiri Call Back Detection
Detect corporate PBX compromised trunks and short-duration robocall spikes designed to trick consumers into calling expensive numbers.
Real-Time Automated Session Teardown
Send immediate SIP BYE or Diameter credit-exhausted messages to Session Border Controllers (SBC) to terminate active fraudulent calls.
Overcoming Mission-Critical Telecom Bottlenecks
How our technical implementations resolve legacy BSS lock-in, subscriber churn, 5G slicing complexity, and revenue leakage.
Massive Financial Losses from Overnight IRSF Attacks
Compromised subscriber accounts and PBXs make hundreds of calls to premium international numbers over weekends, generating $100k+ in uncollectable debts.
Sophisticated SIM Swap Account Takeovers
Criminals bribe rogue retail store workers to swap customer SIMs, intercepting two-factor banking codes and draining customer bank accounts.
Illegal SIM Box Bypass Eroding Interconnect Margins
Grey-market SIM boxes route international incoming calls through domestic SIM cards, depriving carriers of legitimate termination fees.
Disruptive False Positives Blocking Legitimate Subscribers
Crude rule-based firewalls block legitimate business executives traveling abroad, causing customer anger and churn.
End-to-End Carrier Delivery & Rollout Workflow
A disciplined four-stage engineering lifecycle ensuring zero subscriber downtime and seamless core network integration.
Signaling & CDR Tap Setup
Mirror SS7, Diameter, SIP signaling streams, and live CDR mediation feeds into the streaming event ingestion engine.
Behavioral Baseline Training
Train unsupervised machine learning models on historical calling velocities, international destination profiles, and IMEI movements.
Real-Time Detection & Scoring
Evaluate every active call and account transaction against risk matrices, generating sub-500ms fraud probability scores.
Automated Action & SBC Teardown
Trigger automatic call terminations on Session Border Controllers and place temporary locks on compromised subscriber credentials.

Frequently Asked Questions
Direct technical answers regarding TM Forum Open APIs, 5G standalone cores, diameter/HTTP2 mediation, and billing scalability.
What is International Revenue Share Fraud (IRSF) and how does the software stop it?
IRSF occurs when fraudsters use stolen SIM cards or compromised PBXs to generate high-volume calls to expensive foreign numbers shared with corrupt operators. The software detects calling bursts and automatically tears down fraudulent sessions in under 500 milliseconds.
How does the system detect illegal SIM boxes used for interconnect bypass?
The platform analyzes device mobility telemetry. Legitimate mobile phones move across cell towers, whereas SIM box cards remain stationary in one location, make exclusively outbound calls, and cycle through sequential IMEI numbers.
Can the software terminate active fraudulent calls in real time?
Yes. The platform integrates with carrier Session Border Controllers (SBC) and packet gateways. When a fraud threshold is breached, it transmits an automated SIP BYE command that disconnects the call immediately.
How does the system protect subscribers from fraudulent SIM swaps?
The software correlates SIM change requests with device geographic locations, recent password changes, and historical retail agent patterns. High-risk requests trigger mandatory multi-factor validation and temporarily restrict banking verification SMS codes.
Is the platform compliant with STIR/SHAKEN caller ID authentication standards?
Yes. The platform integrates with STIR/SHAKEN certificate authorities and verification engines, inspecting cryptographic SIP identity headers to block spoofed robocalls and illegal call origination.
