Memory-scraping malware

Memory-scraping malware or RAM Scrapping malware is a 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. Some RAM scrapers use the Luhn algorithm to check the validity of card data before exfiltration.[3]

gollark: We need to combine both computer science *and* actual practical stuff, to avoid Electron and also avoid ridiculous weird type insanity.
gollark: Just use a different library for some incredibly obscure archive format nobody can use.
gollark: Ghosts?
gollark: It might be a not-actually-backward-compatible update.
gollark: Perhaps you are forgetting to close the stream or something.
