CDR-Based Fraud Detection

Analyzes Call Detail Records (CDR) in real-time to detect telecom fraud patterns including SIM box operations, IMEI cloning, Wangiri (missed-call) scams, and suspicious night-time activity.

Globe Telecom has blocked over 9 billion spam/scam messages and shut down 145,000+ SIM box operations since 2022.

How CDR Fraud Detection Works
1CDR Ingestion — Real-time call detail records from all network elements streamed into the analytics engine
2Pattern Analysis — Behavioral profiling: call ratios, IMEI tracking, duration analysis, time-of-day patterns
3Anomaly Detection — Statistical outliers flagged: SIM box (high out/in ratio), IMEI clones, Wangiri (short bursts)
4Risk Scoring — Multi-factor risk score combining all detection modules, weighted by severity and confidence
5Auto-Action — Critical alerts trigger automatic SIM blocking, IMEI blacklisting, or manual review queue
