What Are the Most Common UPI Fraud Risks in 2026?
Understanding the regulatory and technology landscape matters. So does understanding the actual fraud methods that most commonly affect real users in 2026.
Fake customer care impersonation is still the most common UPI fraud type, where fraudsters manipulate search engine results to generate fake bank or payment app helpline numbers, and encourage victims to call and provide their OTPs, install remote-access app, or approve collect.
A QR code is used to target sellers and merchants - QR codes are sent to sellers with instructions to "scan for payment," capturing on the general misconception that someone will be credited for scanning a QR code. Scanning always debits.
The request appears as a collect, but is actually a payment request disguised as a refund, cash-back, or official credit - when the victim “approves the request to receive money,” they are actually approving a debit.
Screen-sharing and remote-access attacks - Fraudsters try to convince their clients to install AnyDesk, Teamviewer or other applications, after which they get the full picture of what is going on on the device, even UPI apps and incoming OTPs.
Impersonation and voice cloning (voice synthesis technology becoming more readily available): Voice cloning is a new method of impersonation that is spreading quickly, allowing real-time voice cloning of family members or officials.
Synthetic identity fraud – fraudsters use a combination of real identity elements and false ones to establish an account that clears initial identity checks and subsequently transfer fraudulent money to other accounts and disperse it quickly.
Fund tracing and recovery is made difficult after a fraud, as I4C identified, in 2025, more than 4.5 lakh mule account networks that were used to layer and disperse UPI fraud proceeds.
All of these methods have a common theme: the UPI infrastructure itself is not compromised. User or account is manipulated. That's why improving authentication isn't enough - it's crucial to invest in user education and AI-driven behavioural monitoring at the same time.
How RBI and NPCI Are Building a More Secure UPI Ecosystem
RBI's Role in Digital Payment Security
The RBI's Authentication Mechanisms for Digital Payment Transactions Directions, 2025 (valid from April 1, 2026) are the biggest change in the digital payment security framework since the launch of mandatory 2FA for card transactions in 2009. The directions lay out the rule that two separate methods of payment authentication are to be employed for all digital payment transactions, clarify which types of authentication are acceptable, and mandate that the two types of authentication be rendered independent as much as possible, to create more protection against breaches.
RBI's framework also sets a benchmark for risk-based authentication, which is a permission given to payment systems to properly adjust the level of authentication based on the risk level of the transaction, as opposed to the same amount of friction for all payments, across all contexts.
NPCI's Role in UPI Risk Management
NPCI manages the UPI rails and implements the detailed technical security requirements that make RBI's framework payment level security requirements. In 2026 alone, NPCI has issued several circulars covering various aspects of payment security, such as on-device biometric authentication (OC-201, October 2025); biometric transaction limit increase to Rs 10,000 (OC-226A, July 2026); UPI Circle delegated payment security (OC-201B); and API security guidelines including rate limiting, TPS control, and status-check frequency restrictions (OC-215).
NPCI also oversees fraud chargeback framework that lays down the responsibility of payment service providers and issuing banks in the event of fraud complaints, thereby incentivizing the payment service providers and all stakeholders in the UPI eco-chain to invest in preventing fraud, instead of just the regulatory compliance.
Banks and PSPs as the First Line of Fraud Defence
While RBI sets the framework and NPCI operates the rails, banks and Payment Service Providers are the entities that directly interact with customers and therefore bear primary responsibility for real-time fraud intervention. Banks are required to implement velocity controls (limiting transaction frequency within defined periods), maintain suspicious transaction monitoring systems, enable customer-level alerts for all UPI transactions, and provide rapid account-freeze mechanisms when fraud is reported.
Under the I4C framework, participating banks can receive near-real-time alerts about fraud complaints filed on 1930, enabling them to freeze beneficiary accounts before funds are withdrawn - a capability that has already resulted in Rs 8,031 crore in blocked fraudulent transfers since I4C's launch.
