In March 2007, the company was at the centre of major credit card fraud. Details of customers’ credit cards and debit cards were accessed by computer hackers, exposing 45 million customers to theft. According to the store this affected customers who used their card between January 2003 and June 2004 at any branch of T.K. Maxx. Outside security provider Protegrity has estimated that T.K. Maxx's losses as a result of the data breach may reach 800 million Pounds Sterling in the years to come. The losses would come as a result of paying for credit checks and admistrative costs poor in managing the fallout from the breach.
