That in itself is nothing new. For years gas pumps and ATMs have been targeted, often by hiding tiny magnetic readers that read the data on your credit or debit card when you insert it into the machine. As technology progresses, those once easily-recognized additions have gotten smaller and smaller, to the point that they may be very difficult to recognize, or even be inside the machine where you cannot see them.
Today's report highlights a different approach, one that is far more difficult to detect.Russian-based security company Group-IB recently discovered malware called “Dump Memory Grabber,” which it believes has already been used to steal debit and credit card information from customers using major US banks. Unlike most malware (commonly called computer viruses) you may be familiar with, this malware is actually installed on the ATM or the point of sale registers/kiosks. It harvests everything the device obtains from the user - including everything from the mag stripe as well as potentially the PIN.
