Mobile Money Fraud Trends in West Africa: 2024–2025
How SIM-swap attacks, social engineering and agent network exploitation are evolving — and how to fight back.
By Central Intel Fraud Analytics
Key takeaways
- Agent networks remain the weakest link in many MoMo ecosystems.
- Fraud rings are automating social-engineering at scale via messaging apps.
- Cross-border corridor monitoring catches syndicates early.
West Africa's mobile money ecosystems processed record transaction volumes in 2024 — and criminal actors adapted just as quickly. Fraud is no longer isolated to individual account takeovers; it is industrialised, cross-border and increasingly assisted by compromised insiders.
SIM-swap remains the gateway
Despite operator improvements, SIM-swap fraud persists where identity verification at retail outlets is weak. Attackers target numbers linked to wallets with high float, often timing swaps during weekends when fraud desks are understaffed.
- Integrate telco SIM-change feeds into your fraud engine in near real time.
- Alert customers on alternate channels when MSISDN-linked credentials change.
- Require in-person re-verification for wallet recovery above defined thresholds.
Agent network exploitation
Super-agent hierarchies create concentration risk. We observed syndicates recruiting low-level agents to process cash-out chains, using mule accounts that rotate every 48–72 hours to evade velocity rules tuned for retail behaviour.
“When float moves faster than KYC refresh cycles, you are funding fraud with your own liquidity.”
Social engineering at scale
WhatsApp and Telegram campaigns impersonating regulators, lottery operators and even internal IT support drive credential harvesting. Deepfake voice calls are emerging in Nigeria and Ghana targeting helpdesk reset workflows.
Detection patterns that work
- Graph analytics linking devices, agents and beneficiaries across corridors.
- Behavioural baselines per agent tier — not one-size-fits-all velocity caps.
- Shared intelligence with peer FIs via sector ISACs where available.
