Visa Security Alert (PSI): Attacks Targeting Point-Of-Sale at Fuel Dispenser Merchants
In August and September 2019, Visa Payment Fraud Disruption (PFD) investigated two separate breaches at North American fuel dispenser merchants. The attacks involved the use of point-of-sale (POS) malware to harvest payment card data from fuel dispenser merchant POS systems. It is important to note that this attack vector differs significantly from skimming at fuel pumps, as the targeting of POS systems requires the threat actors to access the merchant’s internal network.

Visa Security Alert (PSI): New JavaScript Skimmer 'Pipka' Targeting eCommerce Merchants Identified
In September 2019, Visa Payment Fraud Disruption’s (PFD) eCommerce Threat Disruption (eTD) program identified a new JavaScript skimmer that targets payment data entered into payment forms of eCommerce merchant websites. PFD is naming the skimmer Pipka, due to the skimmer’s configured exfiltration point at the time of analysis (as shown below in the Pipka C2s). Pipka was identified on a North American merchant website that was previously infected with the JavaScript skimmer Inter, and PFD has since identified at least sixteen additional merchant websites compromised with Pipka.

Visa Security Alert (PSI): eCommerce JavaScript Skimming Campaign Targeting Service Providers
In April 2019, there have been at least eight eCommerce service providers who had been targeted with JavaScript skimming attacks. Visa Payment Fraud Disruption (PFD) found the same malware and the same infrastructure for data exfiltration used across these eight cases. In July 2019, researchers reported that these service provider attacks were much more significant than initially believed and affected over 17,000 domains that integrated code from the service providers targeted in April. The attacks were reportedly successful due to an automated process whereby the attackers scanned for misconfigured write permissions in a widely-used content delivery network (CDN).

Visa Security Alert (PSI): Alina Point-of-Sale (POS) Malware Classifications
In June 2019, Visa’s Payment Fraud Disruption (PFD) analyzed a malware sample from the recent compromise of a North American hospitality merchant and identified the malware as a variant of the Alina Point-of-Sale (POS) malware family. Alina dates back to at least 2013, and is one of many malware strains that possesses a Random Access Memory (RAM) scraper, which is specifically designed to steal payment account information from the memory, or RAM, of the targeted system. Given the upload and compile dates, and recently observed operations leveraging Alina, PFD assesses Alina POS is in active use and remains a popular malware variant for POS targeting.

Visa Best Practices for Tokenization Version 1.0
In October 2009, Visa published the Visa Best Practices for Data Field Encryption to promote the proper encryption of sensitive card data that is transmitted, processed or stored by stakeholders throughout the payment system. As part of these best practices, Visa recommended that entities use tokens (such as a transaction ID or a surrogate value) to replace the Primary Account Number (PAN) for use in payment-related and ancillary business functions. Tokenization can be implemented in isolation or in concert with data field encryption to help merchants eliminate the need to store sensitive cardholder data after authorization. Entities that properly implement and execute a tokenization process to support their payment functions may be able to reduce the scope, risks and costs associated with ongoing compliance with the Payment Card Industry Data Security Standards (PCI DSS).
