A new report from BioCatch, which prevents financial crime by recognizing patterns in human behavior, highlights an 11% increase in fraud and scams originating from mobile channels in the UK, as fraudsters pivot away from social engineering voice scams, which declined by 34%. The research pulls data from a dozen different UK banks servicing more than 110 million retail banking customers in the country.

“We continue to see results from UK banks increasing their efforts to detect social engineering scams,” BioCatch Director of Global Fraud Intelligence Tom Peacock said. “Unfortunately, the decrease in social engineering voice scams observed in this report likely just means all that fraud migrated elsewhere. We know, for example, card fraud has increased, as has fraud conducted from mobile devices, correlating with a 6% spike in stolen-device fraud and a recent iOS update allowing remote control of iPhones for the first time in the product’s history.”

The report, 2025 Digital Banking Fraud Trends in the UK, also includes a case study showcasing how behavioral and device intelligence identifies suspicious payments in a sophisticated investment scam lasting months. In this instance, 90% of reported fraud payments occurred while the user was on a call and 80% took place on a device with multiple displays (suggesting the possibility of remote access).

“While the decline in voice scams represents progress,” BioCatch Global Advisory Director for EMEA Jonathan Frost said, “if, overall, fraud is not declining in the UK, we must consider the possibility that we’ve displaced rather than banished fraud losses. Anticipating this possibility both buys us more time to plan and gives us the opportunity to consider all potential scenarios.”
