Network defense solutions should also be employed as they can detect unusual network behavior, like the installation of malware across numerous devices or the amount of data being moved within the network. Allowing only specific apps to run in the system will make it harder for malware to run on PoS devices. For instance, PoS systems could benefit from whitelisting or locked down systems. Real time identity theft monitoring is highly recommended.īusinesses should check to see if their existing set-ups could be improved. Regularly monitoring statements is a good way to check for fraudulent purchases, data breach or not. However, users should still be vigilant about protecting their accounts. This malware was said to be found in PoS systems of popular establishments, hotels, and other businesses.Īdmittedly, PoS malware is more of a concern for retailers than customers. Reports of this family surfaced around the end of 2012. Security researchers believe these malware are part of the BlackPOS/Kaptoxa malware family.Īnother PoS malware family that gained notoriety is the DEXTER PoS family. Analysis indicated that the malware involved in this breach are detected as TSPY_POCARDL.AB and TSPY_POCARDL.U. PoS malware received a lot of attention from the public after it was revealed that US retailer Target suffered a massive data breach that affected an estimated 110 million customers- nearly a third of the US population. To use the stolen information, a person has to physically clone the credit card.

The magnetic strip and the chip do not contain the CVV2-the three-digit code on the card that’s required for online shopping. The stolen information cannot be used to make purchases online. It comes as no surprise then that most PoS malware come equipped with backdoor and command-and-control features. Once inside, the PoS malware can select which data to steal and upload to a remote server.
Such may include default login credentials or compromised partner systems. In order to perform RAM scraping, PoS malware often look for security lapses to enter the system. PoS malware specifically target the RAM to steal the unencrypted information-a process called "RAM scraping." Decryption only occurs in the PoS device’s random-access memory (RAM), where it is processed. The payment card industry uses a set of security standards that enforce end-to-end encryption of sensitive payment data-which comes from the card’s magnetic strip or chip-when it is transmitted, received or stored. However, because of the nature of PoS devices, routines of PoS malware differ from other data stealing malware. The goal of PoS malware is to steal information related to financial transactions, including credit card information. On the flip side, it also means that malware can run on these systems, given that these are like stripped-down computers.

The decision to run on Windows could be seen as an advantage: it’s easier to run, maintain, and develop apps for devices running on Windows. Most PoS devices run on some variant of Windows and Unix. PoS devices are connected to the Internet to authorize transactions by sellers.
It calculates the amount customers must pay for their purchases and provide options for customers to make said payment. A PoS device is designed to complete a retail transaction.
