Though credit card processing is as important as it has ever been to the operation of a point of sale store, a proliferation of malware-based attacks has increased the already high need for strong security measures and better authentication, in order to deter these kinds of breaches. The recent Schnucks hack can be seen as one example of the way a business can be caught off-guard by criminal activity of this nature, but others can learn to look for higher standards when establishing a workable POS system and perhaps insist on better encryption and protection of user data.

Earlier this month, another store chain found itself the victim of a card data breach. This time, it was MAPCO Express and its related stores, with more than 370 locations over multiple states primarily in the south and southeast, that saw vulnerable customer information exposed, even though no specific numbers of victims or losses appear to have been named. As with the Schnucks case, these attacks go back months, as far as mid-March.

While the official press release from the company regarding the issue doesn't offer much information on the specific means used to steal data, it does quote the company's Vice President of Operations, Troy Miller, as insisting on finding out more and learning from this experience.

"Through our internal investigation and collaboration with forensics security firms, we have disabled the malware that was used in this incident while establishing additional safeguards designed to prevent this from happening in the future," he says. 

Companies put in a similar position can demand better checks for the POS credit card processing software they use and perhaps have plans in place to prepare for this (unfortunately) common occurrence.
