Payment card data is among the most widely distributed information on the Dark Web. The breadth of data for sale in underground marketplaces can prove helpful to security teams, who can analyze this information and combine it with other threat data to learn their potential exposure and mitigate the impact of an incident, Flashpoint researchers advise in a new report.
The ecosystem for stolen payment card data ranges from low-level markets selling cards recycled from past breaches, to top-tier sellers with unused card data directly pulled from a new breach. Joker’s Stash is one of the most prominent payment card retailers on the Dark Web, where it has been selling credit cards from online and physical transactions since 2014. In 2015, it began to also sell personally identifiable information including Social Security numbers.
A recent update on Joker’s Stash arrived on Oct. 29, when it added data pertaining to more than 1.3 million credit and debit cards reportedly taken from banking customers in India. The data dump released was one of the largest in Joker’s Stash’s history, researchers report, with pricing information valued at $100 per card, which put the total for the database at $131 million.
Joker’s Stash and similar marketplaces provide value beyond cybercrime, researchers say. Fraud teams can leverage its data to learn what card data is for sale and the timing of its availability on Joker’s Stash. This reveals the common point of purchase (CPP) of compromised cards and can help identify the geographical source of a breach and stem its potential impact, they explain.
