Account Enumeration is a prolific problem that affects issuers, merchants, and acquirers globally. Cybercriminals are taking advantage of big data and artificial intelligence to find and exploit new vulnerabilities. To conduct fraudulent eCommerce transactions, cybercriminals use scalable and programmatic automated testing of common payment fields, a method also known as account enumeration. This guide will provide an overview for merchants on implementing mitigation techniques to help bolster their merchant website and ensure they are not susceptible to these enumeration attacks.
In May and June 2020, respectively, Visa Payment Fraud Disruption (PFD) analyzed malware samples recovered from the independent compromises of two North American merchants. The recent attacks exemplify threat actors’ continued interest in targeting merchant POS systems to harvest card present payment account data. PFD is providing the analysis of these malware variants and the corresponding indicators of compromise (IOCs) to assist in the identification, prevention, and mitigation of attacks using the malware.
With the recent Magento 1 'end-of-life' support, merchants with online stores deployed on Magento 1 will lose all access to new features, functionality updates, bug fixes, and support from Adobe/Magento. Most importantly, any future vulnerabilities will no longer be addressed with new security patches from the company, leaving the unsupported versions of Magento exposed to security or data compromise incidents.
However, Magento is not the only targeted website platform and so the purpose of this guide is to provide ecommerce merchants with recommendations to keep their websites secure in order to avoid a security or data compromise incident.
In February 2020, Visa Payment Fraud Disruption (PFD), using the eCommerce Threat Disruption (eTD) capability, identified a previously unknown ecommerce skimmer, and named the skimmer 'Baka.' PFD identified this unique skimmer on several merchant websites across multiple global regions using Visa’s eTD capability, which analyzes and detects threats targeting eCommerce merchants.
Pandemic unemployment assistance (PUA) fraud is a significant consequence of the ongoing COVID-19 pandemic and remains prolific as the pandemic persists. Visa Payment Fraud Disruption (PFD) previously identified the use of mobile payment applications to facilitate PUA fraud. Throughout July 2020, PUA fraud continued, and PFD identified new tactics used by threat actors to conduct this fraud.
Visa Payment Fraud Disruption (PFD) analyzed malware samples recovered from the compromise of a North American merchant. The malware variants were identified as Alina POS, Dexter POS, and TinyLoader. These malware variants were deployed on the merchant network in an effort to harvest track 1 and track 2 magstripe payment card data from the merchant’s point-of-sale (POS) environment. However, the targeted merchant had EMV® Chip enabled point-of-sale terminals. The implementation of secure acceptance technology, such as EMV® Chip, significantly reduced the usability of the payment account data by threat actors as the available data only included personal account number (PAN), integrated circuit card verification value (iCVV) and expiration date. PFD is providing the indicators of compromise for merchant network security purposes.
Visa is committed to enhancing both the security and quality of payment services available in both card-present and card-not-present environments. This fact sheet provides useful information related to the upcoming end of life for all Magento 1 websites.
In summer 2019, Visa Payment Fraud Disruption (PFD) identified three unique attacks targeting merchant point-of-sale (POS) systems that were likely carried out by sophisticated cybercrime groups. PFD recently reported on the observed increase of POS attacks against fuel dispenser merchants, and it is likely these merchants are an increasingly attractive target for cybercrime groups. Track 1 and track 2 payment card data was at risk in the merchant’s POS environments due to the lack of secure acceptance technology, (e.g. EMV® Chip, Point-to-Point Encryption, Tokenization, etc.) and non-compliance with PCI DSS. The activity detailed in this alert highlights continued targeting of POS systems, as well as targeted interest in compromising fuel dispenser merchants to obtain track data.
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 hosted a webinar to review requirements, procedures and timelines for reporting and responding to a suspected or confirmed account data compromise event. In addition, the webinar will explore compromise trends and fraud schemes and the suite of Visa security capabilities designed to prevent and disrupt payment fraud.
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.
Based on Visa Payment Fraud Disruption’s (PFD) analysis of eCommerce compromises throughout 2018, FIN6’s focus on the CNP environment has only amplified, suggesting that the cybercrime group has fully incorporated targeting CNP environments into their criminal methodology.
Visa’s Payment Fraud Disruption (PFD) team was the first to link the exact same PwnPOS malware file hash across seven recent point-of-sale breaches reported since March 2018 in North America. It was also found that each of the PwnPOS malware files recovered from the 2018 breaches were the same across all compromises, rendering PwnPOS an easily identifiable malware family.

Visa has been working with merchants, acquirers, and fuel-industry providers to support migration to the more secure EMV technology. The EMV liability shift is designed to better protect all parties. With the new rules, the party that is the cause of a chip transaction not occurring, either the issuer or acquirer, will be held financially responsible for any resulting card-present counterfeit fraud losses. However, due to challenges with EMV Automated Fuel Dispensers (AFD) solution readiness, Visa is delaying the U.S. domestic AFD EMV liability shift date to 1 October 2020.
New options for merchants in the U.S. & Canada From 14 April 2018, EMV-enabled merchants in the U.S. and Canada have the option to stop capturing signatures as a method of cardholder verification. Those same merchants will also no longer be required to retain and store transaction receipts.
Fuel dispenser chip card acceptance is the more secure way to accept Visa cards at your fuel dispensers, and the best way to avoid liability for counterfeit fraud. The sooner it is done the better for a number of reasons.
