Three of the biggest fraud trends from MRC Vegas 2026
Fraud is becoming more automated, adaptive, and difficult to detect with traditional rules-based systems. At MRC Vegas 2026, leading fraud teams emphasized dynamic authentication, fraud controls embedded directly into agentic payments, and layered identity verification to address deepfakes and synthetic identities. The common goal is to reduce friction for trusted customers while applying stronger defenses where risk is highest. ## Dynamic Authentication Based on User Intent - Universal authentication creates unnecessary friction, increases false positives, and can cause businesses to lose legitimate customers and their long-term value. - Airbnb advocates building behavioral profiles over time to measure “high-trust velocity”—the likelihood that a user’s activity reflects legitimate intent. - Trusted users can proceed without additional challenges, while authentication is reserved for the small percentage of traffic proven to be risky. - Stripe Radar’s adaptive 3DS uses AI to trigger authentication only when transaction behavior appears unusual. - Stripe reports that eligible businesses have seen fraud reductions of more than 30% with this approach. ## Fraud Detection for Agentic Commerce - Ashley Furniture’s existing rules-based system handled different authorization needs for quick-ship products and custom orders. - That model became insufficient when AI agents began making purchases across channels. - Fraud detection must be part of the payment infrastructure and evaluate transactions in real time, rather than analyzing them only after purchase. - Stripe Shared Payment Tokens let agents use a customer’s saved payment method without exposing payment credentials. - Combined with Stripe Radar, these tokens transmit risk signals such as potential disputes, card testing, stolen-card usage, and issuer declines. - These signals help distinguish legitimate, high-intent agents from low-trust automated bots. ## Deepfakes and Synthetic Identity Fraud - Fake identities are easier to create because criminals can access document templates and generative AI impersonation tools. - Fraudsters may produce convincing fake IDs, images, voices, and videos with limited resources. - Effective verification depends on identifying inconsistencies that forgeries fail to reproduce, such as incorrect signatures, mirrored photos, or mismatched expiration dates. - No single verification check is reliable enough; multiple independent checks are necessary. - Stripe Identity uses AI to detect fake documents and spoofed photos, compare ID images with selfies, and validate Social Security numbers and addresses against databases. Businesses should replace blanket controls with risk-sensitive interventions: minimize friction for trusted users, integrate fraud detection into agent-driven payment flows, and use layered identity verification to catch increasingly convincing forgeries.
