Cross-bank fraud intelligence: industry consortium pilot

Контекст

4 коммерческих банка УЗ. Each имеет fraud detection capability, но cross-bank fraud (атакующий перемещается между банков) invisible. Известные patterns: SIM swap → account takeover → cash-out через secondary банк.

CRO банков joint discussion — shared intelligence framework через industry consortium.

Диагностика (4 недели)

Sample analysis:

• ~30% suspected fraud cases involve crossborder между банками.
• 12% recovered fraud could have been prevented с early cross-bank signals.
• Regulatory framework для shared fraud intelligence — emerging, не fully formed.

Подход (9 месяцев)

Месяцы 1-3. Clean room architecture + legal framework. Privacy-preserving signal sharing — hashed identifiers, no raw PII.

Месяцы 3-5. Regulator engagement. Cbu.uz dialogue для legal framework approval.

Месяцы 5-7. Platform pilot. Each bank publishes fraud signals (hashed customer ID + risk score), consumes others’. Real-time matching.

Месяцы 7-9. Operating routine. Daily signal exchange, monthly cross-bank fraud committee, quarterly metrics review.

Результаты

После 9 месяцев:

• Cross-bank fraud detection rate +60%.
• Estimated fraud prevention $2.4M annualized across 4 banks.
• False positive rate maintained — strict matching protocols.
• Regulator approval for framework — позитивный precedent.
• Industry consortium expanded to 7 banks в follow-up phase.

Что критически важно

CRO leadership across banks — coalitiуn essential.

Privacy-preserving architecture — без compromise on customer data.

Regulator engagement — key для legal framework.

Clear value sharing — все participants benefit equally.

Что не сработало бы

Bilateral data sharing — too complex, no scale.

Raw data sharing — regulator violation.

Industry-wide без regulator buy-in — legal risk.
