Visa Warns Fraud Is Rising Alongside “AI Agent” Shopping

Visa says the spread of AI-driven shopping agents is creating fast-moving fraud that no single organization can fight alone. Because these crimes cross borders, Visa urges payment networks, banks, regulators, law enforcement and technology firms to share intelligence and adopt common verification checks.

The company says criminals now use autonomous shopping agents and generative AI to run scams at scale. These agents compare prices, find sellers and complete purchases automatically. By removing human review, attackers can automate scams from start to finish, using fake websites, cloned brands and bogus customer-service agents that are hard for people and systems to detect.

Visa’s Payment Fraud Disruption team reported a more than 450% increase in dark-web posts about “AI Agent” tools over the past six months. The firm also recorded a 25% rise in bot-driven malicious transactions worldwide, with a 40% jump in the U.S.

One tactic is to manipulate an agent’s logic so a counterfeit merchant appears as the “best” deal. Fraudsters make fake sellers pass automated checks, causing AI agents to complete purchases with stored payment details. Attackers then capture that payment data and use it for immediate unauthorized transactions.

Another threat uses embedded conversational AI on scam sites to pose as customer support. These AI helpers keep victims engaged for days or weeks, discourage contact with banks and delay fraud reports long enough for criminals to act undetected.

Visa advises coordinated action now: share threat data, set shared verification standards, and build tools that can detect automated and AI-enabled scams before they succeed.
