Thousands of Asda customers’ personal information and financial details could have been hacked over the past two years due to a bug in its website.
The supermarket chain, which is owned by US retailer Walmart, processes hundreds of thousands of online orders each week, including for its clothing brand George. But a flaw in its website meant some details were exposed to the risk of hacking, the BBC reports.
Asda said it has now fixed the problem and no customers had been affected.
The company said: “Asda and Walmart take the security of our websites very seriously. We are aware of the issue and have implemented changes to improve the security on our website.
“The points flagged pose a low risk to customers and our monitoring of these security issues indicate that no customer information has been compromised over that two-year period.
“The small risk to customer information has been removed and an update has been applied, we’re now adding further enhancements.”
