How To Defend Point-Of-Sale Systems

US-CERT gives advice on defending POS systems against attacks like those against Target, Neiman Marcus.

Major hacks at retailers that include Target and Neiman Marcus have put a new spotlight on the security of point of sale (POS) systems. What may come as a surprise to some is that the recent memory-scraping malware attacks were nothing new. Last year, Visa published two "Visa Data Security Alerts" warning merchants of an increase in attacks targeting credit card data with specific references to memory-scraping malware.

The alerts were published in April and August. The first stated that Visa has seen an increase in network intrusions involving grocery merchants since January 2013. August's update used nearly the same verbiage but mentioned retail instead of grocery. The part that's of particular interest is how the attackers were carrying out the attacks.

"Once inside the merchant's network, the hacker will install memory parser malware on the Windows based cash register system in each lane or on Back-of-the-House (BOH) servers to extract full magnetic stripe data in random access memory (RAM)."

It is amazing how hackers have been able to get into some of the largest databases in the world. A lot of people are on edge right now with their compromised security. Hopefully the Government can set up better defenses in the future.

I didn't realize that memory-scraping malware was so common. I tend to take more precautions than most people when it comes to my personal information. I had my identity stolen once and that is where I drew the line and decided tha tI wouldn't let it happen again.
