BOSTON—Kroger says personal data, including Social Security numbers of some of its pharmacy and clinic customers, may have been stolen in the hack of a third-party vendor’s file-transfer service.
The Cincinnati-based grocery and pharmacy chain said in a statement Friday that it believes less than 1 percent of its customers were affected—specifically some using its Health and Money Services—as well as some current and former employees because a number of personnel records were apparently viewed.
