Threats to Micro ATMs
With respect to POS data vulnerabilities, there are three specific areas that should be given attention in-cluding data in memory; data in transit; data at rest. Data in memory in this context is when the card track data is brought into the system at the POS system via a POI (Point of Interface or some other input device). Data in memory is nearly impossi-ble to defend if an attacker has access to the POS sys-tem. Traditionally, data input into the POS system was in memory in clear text, which is what allowed, attackers¿ memory scrapers to be very successful. The way to min-imize this risk is by encrypt-ing the card data as soon as possible and keeping it en-crypted to the maximum ex-tend throughout its life with-in the system. Point to Point Encryption (P2PE) could be used to address the issue of encrypting data in memory.
Skimming is the theft of credit card / Debit card infor-mation. Thief can obtain vic-tim’s credit card number us-ing a small electronic device near the card acceptance slot and store hundreds of victim’s credit card numbers.
Social engineering involves gaining trust - hence the fraudster poses as a mem-ber of staff. The fraudster would then ask the customer to check the card for damag-es. The fraudster would have gained confidence from his prey using various tactics such as offering assistance to the customer who per-haps would have tried to use the ATM without success or perhaps the customer who is not familiar with use of micro ATM machine and requires assistance.
