Dexter Malware Targets POS systems

Many of you may have heard about the recent Dexter Malware that has infiltrated POS systems worldwide.  In case you haven't, here is a link for more information about it.

The good news is it cannot infect your Mac as it is only on other platforms.  Nor can it intervene in MacPOS credit card processing as it employs Triple DES encryption of sensitive card information that prevents thieves from skimming that from your POS system.

An excerpt from securitywatch.pcmag.com :


Encryption As Defense If the data collected by the PoS software had been encrypted, Dexter would not have been able to do anything with the stolen data. If the business had encrypted the data from the moment it was captured, either by swiping the card's magnetic data or paid in cash. Even encrypted, the format and integrity is retained, so the software can still access the data without any problems.  As far as the attacker is concerned, there's nothing of value to steal.
"Dexter would get nothing but useless encrypted data," Bower wrote on the Voltage Security blog.

Be assured that when using MacPOS and Mercury Payments for your credit card processing that you will not have to deal with these kind of security problems.
