s, that is the interception of the processing at the retail checkout point of sale system. The simplest, or most evasive, approach is RAM-scraping, accessing the system's memory and exporting the copied information via a remote access trojan (RAT) as this minimizes any software or hardware tampering, potentially leaving no footprints. POS attacks may also include the use of various bits of hardware: dongles, trojan card readers, (wireless) data transmitters and receivers. Being at the gateway of transactions, POS malware enables hackers to process and steal thousands, even millions, of transaction payment data, depending upon the target, the number of devices affected, and how long the attack goes undetected. This is done before or outside of the card information being (usually) encrypted and sent to the payment processor for authorization.
