Symantec documents that high risk during the forthcoming holiday seasons still remains high.  While it is likely many companies have strengthened controls, it still is a cat-and-mouse game in staying ahead of latest malware developments

As Americans gear up for another holiday shopping season, the threat posed by point-of-sale malware remains high. More than a year after the discovery of the first major attacks against POS networks, many US retailers are still vulnerable to this type of attack and are likely to remain so until the complete transition to more secure payment card technologies in 2015.

While some retailers have enhanced security by implementing encryption on their POS terminals, others have not and retailers will continue to be a low-hanging fruit for some time. While the introduction of new technologies will help stem the flow of attacks, it will not eliminate fraud completely and attackers have a track record of adapting their methods.
