Network Approach
  1. A slightly older yet popular way for hackers was to interrupt X.25 network with MITM (Man In The Middle) hack.
  2. This hack essentially makes the ATM understand that it has received authorization to dispense money at the request of the hacker.
  3. ATM has to be working on X.25 network for this hack to succeed.
False processing center
  1. In this method an attacker needs to contact a cable that has connected the machine to the network.
  2. The hacker separates the ATM from the bank’s network and then connects it to an appliance that acts as a fake processing center.
  3. After that the box is used to control the cash tray and send commands to the ATM, requesting money from the selected tray.
  4. Hence, the attacker can now use any card or input any PIN code, and the false transactions will look valid.
A remote attack on several ATM’s
  1. This method entails an insider working in the target bank.
  2. The criminal acquires a key from the insider that opens the ATM body.
  3. The key does not give an attacker access to the cash trays, but it depicts the network cable.
  4. The hacker detaches the ATM from the bank’s network and plugs in a special appliance that sends all of the data to their own server.
Card skimmers

  3. A black box in this case is a device that allows an attacker to control the ATM’s cash trays.
  4. Meanwhile the invader messes with the ATM, its screen displays a service message like “Maintenance in progress” or “Out of service,” moreover, the black box can be controlled wirelessly via a Smartphone.
  5. The hacker just hit a button on the screen to get the cash and then set out the black box to hide the evidence that the machine was on hold.
ATM master key
  1. This method grants you access to ATM’s maintenance mode where you can withdraw funds from the ATM by manipulating ATM software.
  2. And no one’s account would get debited .
  3. This method can be used to withdraw cash from ATM without actually meddling with the machine or causing any damage.
  4. One needs to visit the target ATM first to check the manufacturer and model details.
  5. Once you have them, just go to ebay or AliBaba and find the suitable ATM maintenance master key.
  6. Master key will lead you to the motherboard of the ATM where you can plug in the update USB key and withdraw all the cash in the machine.
Malware attacks

There are two ways to taint a target ATM with malware:

  1. By Inserting a malware-laced USB drive into the port or by tainting the machine remotely.
