Black box attacks are a type of jackpotting attack aimed at forcing an ATM to dispense the cash by sending a command through a “black box” device.
In this attack, a black box device, such as a mobile device or a Raspberry, is physically connected to the ATM and is used by the attackers to send commands to the machine.
The ATM black box attacks are quite popular in the cybercrime underground and several threat actors offer the hardware equipment and malware that could be used to compromise the ATMs.
This week, Diebold Nixdorf, a leading manufacturer of ATM machines, has issued an alert to customers warning all banks of a new variant of ATM black box or jackpotting attacks.
