Memory-scraping malware

Memory-scraping malware is malware that scans the memory of digital devices, notably point-of-sale (POS) systems, to collect sensitive personal information, such as credit card numbers and personal identification numbers (PIN) for the purpose of exploitation.[1]

Operation

The magnetic stripe of payment cards hold three different data tracks – Track 1, Track 2 and Track 3.[2] The POS RAM scrapers were created to implement the use of expression matches to gain access and collect the Track 1 and Track 2 card data from the RAM process memory. RAM scrapers also use Luhn algorithm to reach access and ex-filtrate victim's card data.[3]
