2. Introduction

Unified Payments Interface (UPI) is the heart of India’s fintech revolution. Its open API-based model enables innovation — but also attracts fraudsters. With billions of dollars transacted daily, UPI is a prime global fraud target.

3. NPCI’s Mandate

NPCI regulates UPI with RBI oversight. Its fraud guidelines are mandatory for:

Banks (Issuer & Acquirer).
Payment Service Providers (PSPs).
Third-party app providers (TPAPs).

4. Evolution of UPI Fraud

MFA mandatory (device binding + OTP + UPI PIN).
Transaction velocity controls.
AI/ML-based anomaly detection.
QR code scanning safeguards.
Mandatory dispute redressal within 7 days.

6. Authentication & MFA

Device fingerprinting.
OTP + PIN combination.
Account reactivation cooling periods.

7. Device Binding & SIM Swap Defense

SIM swap detection mandatory for banks.
Rebinding → requires re-verification.
New device lockouts for 24–48 hours.

8. Transaction Monitoring

Fraud scoring engines.
Blacklisting mule accounts.
AI-based velocity alerts.

9. QR Code Security

Push for dynamic QR codes.

10. Consumer Awareness

PSPs must display: “Do not share UPI PIN/OTP.”
NPCI runs TV & digital campaigns.

11. Dispute Resolution

17. Threat Hunting Playbooks

Splunk query (detect velocity fraud):

index=upi_txn sourcetype=transactions
| stats count by user_id, device_id
| where count > 10 within 60s

Elastic query (detect mule accounts):

event.dataset:"upi" AND transaction.amount < 500
AND transaction.count > 100

18. Fraud Analytics
