Mobile Money Security — study & article (in progress)
Why. Mobile Money (MTN MoMo, Airtel Money) carries a huge share of payments in Africa — concentrating as much value as risk: fraud, social engineering, merchant-side integration weaknesses, reconciliation.
What I study, from the integrator/merchant side:
- Transaction lifecycle and break points (USSD, API, callbacks/webhooks).
- Fraud & abuse: replay, idempotency, double-spend, SIM-swap, phishing.
- Reconciliation merchant ↔ operator and anomaly detection.
- Hardening integrations (signatures, secrets, logging, least privilege).
Prototyping stack
Node.js/NestJS · PostgreSQL · Webhooks · Observability
Study / R&D — research & prototyping (article in progress), deliberately generic (no specific vulnerability disclosed). Not deployed to production.
