Vortex's TSS Protection from Black Box Attacks

Protect Your ATMs against Black Box attacks

Automated Teller Machines (ATMs) being the foremost point of contact for the customers with their banks, are vulnerable to a gamut of malware and logical attacks. “Black Box” is the most prevalent and sophisticated logical attack executed by the cyber-criminals to cash-out or jackpot the ATMs.

Attack Methodology

’Black Box’ is a cash jackpotting attack on ATMs, executed with the help of an unauthorized device connected to the ATM which will replace the active core and act as the proxy core sending commands to the cash dispenser to dispense the cash.

Black Box Attack Methodology in order

According to the survey conducted by the European Association for Secure Transactions (EAST), the number of black box attacks on the ATMs witnessed a signficant increase of 269% in the first half of 2020 over the same period in 2019. Loss of one million euros reported to the banking community and this has a potential to increase to more alarming levels if left unchecked. Cyber-criminals are more active in executing numerous logical attacks on the ATMs. ‘Black box’ attacks must be considered as a very serious threat and security systems in place must be to the highest level.

Dispenser Host Pairing and Encryption

ATMs can be protected from black box attacks through effective host pairing and encrypted communication between the ATM’s core and the cash dispenser. Ecoteller® ATMs are equipped with a robust host pairing mechanism between the core and the cash dispenser. As a result of this, the Vortex cash dispenser will accept commands only from the core it has been paired with. In addition to this, the communication between the core and the cash dispenser is encrypted such that it is not possible to reverse engineer the communication between the core and the cash dispenser. Dispenser host pairing and encryption is a security module available with Vortex’s Terminal Security Solution. As we witness an upsurge in the black box attacks on the ATMs, it will be a prudent measure to safeguard the interest of the banking community by deploying the highest level of security features in the ATMs.
