A dump of hundreds of thousands of active accounts is aimed at promoting AllWorld.Cards, a cybercriminal site for selling payment credentials online. The leaked credit cards include the following fields: Credit-card number, expiration date, CVV, name, country, state, city, address, ZIP code, email and phone number. Cybercriminals get their hands on card data in a number of ways, including point-of-sale skimmers, targeted Magecart attacks and info-stealing trojans.
