VISA Warns of Ongoing Cyber Attacks on Gas Pump PoS Systems

The point-of-sale (POS) systems of North American fuel dispenser merchants are under an increased and ongoing threat of being targeted by an attack coordinated by cybercrime groups according to a security alert published by VISA.

Three attacks that targeted organizations in this type of attack with the end goal of scraping payment card data were observed during the summer of 2019, according to the Visa Payment Fraud Disruption (PFD).

[...] PFD says that in the first incident it identified, unknown attackers were able to compromise their target using a phishing email that allowed them to infect one of the systems on the network with a Remote Access Trojan (RAT).

This provided them with direct network access, making it possible to obtain credentials with enough permissions to move laterally throughout the network and compromise the company's POS system as "there was also a lack of network segmentation between the Cardholder Data Environment (CDE) and corporate network."

The last stage of the attack saw the actors deploying a RAM scraper that helped them collect and exfiltrate customer payment card data.

During the second and third incidents, PFD states that the threat actors used malicious tools and TTPs (Tactics, Techniques and Procedures) attributable to the financially-motivated FIN8 cybercrime group.
