Hackers evaded security systems for a year-and-a-half at a hosting center that processed payment cards for Goodwill Industries. Hackers used the same type of malware that struck Target and other major retailers. C&K Systems of Murrells Inlet, S.C., said two other customers were also affected by the unauthorized access. Goodwill said in July that federal authorities were investigating a possible payment card breach at its U.S. outlets. Of the “many” payment cards that may have been compromised, it said, it knows of “less than 25″ so far.”]
