The Associated Press reports yet another data security breach — this time involving customers of retailer Target:
MINNEAPOLIS — Target says that about 40 million credit and debit card accounts may have been affected by a data breach that occurred just as the holiday shopping season shifted into high gear.
The chain said that customers who made purchases using their cards at its U.S. stores between Nov. 27 and Dec. 15 may have been exposed. […]
Target Corp. advised customers who suspect there has been unauthorized activity on their cards should call them at 866-852-8680.
Target is just the latest retailer to be hit with a data breach problem. TJX Cos., which runs stores such as T.J. Maxx and Marshall’s, had a breach that began in July 2005 that exposed at least 45.7 million credit and debit cards to possible fraud. The breach wasn’t detected until December 2006.
