Santander UK has sounded the alarm over a growing wave of fake AI-generated social media adverts that threaten to deceive shoppers during the peak Christmas buying season.
To expose the scale of the risk, the bank has created 10 fabricated AI adverts mirroring common wishlist items, demonstrating how convincing these scams can be. The initiative aims to teach consumers how to detect the subtle signals behind fraudulent digital offers.
Research commissioned by Santander UK revealed that over half of adults fear falling victim to AI-driven purchase scams, with 56% believing they or a family member could be duped. Half of respondents admitted they no longer know what to trust when shopping online. The warning comes after £16.7m was stolen in purchase scams last year, with 67% of cases originating via social media channels.
Despite being considered digitally savvy, younger demographics appear particularly at risk. Among Gen Z users, 51% claimed they had spotted fake AI adverts circulating online. However, almost one in six — 14% — disclosed that they had already lost money to fraudulent ads. With Christmas buying accelerating, 52% of people reported increased caution due to rising AI-generated fraud attempts, and 63% said they were so concerned they would avoid buying products directly via social platforms.
Santander’s head of fraud risk management, Chris Ainsley, said the evolving threat landscape demands greater awareness. Santander UK head of fraud risk management Chris Ainsley said, “Generative AI has opened the floodgates to a new wave of highly convincing scams that can be almost impossible to spot at first glance. As fraudsters become more sophisticated, it’s vital that people stay alert and think twice before engaging with adverts or offers that appear to- good to be true. We want to make sure everyone knows what to look for so they can shop online with confidence, particularly as we head into one of the busiest shopping periods.”
Santander’s analysis also highlighted how easily people are fooled by fabricated promotions. Nearly three-quarters — 74% — were unable to detect that a padel bat advert was false, while 71% failed to recognise that an AI-generated dog feeder listing was fraudulent.
The bank emphasised several tell-tale warning signs, including unrealistic pricing, manipulated imagery, unusual website addresses, and insecure payment portals that lack https:// in the domain. Poor grammar, inconsistent branding and generic urgency-driven messaging were also cited as indicators of bogus advertising. By showcasing artificial examples and outlining clear red flags, Santander hopes to educate customers and encourage vigilance as digital shopping surges.
