Credit Card Skimming Attack Uses Telegram

Popular Messaging App Telegram Used to Exfiltrate Payment Cards in Digital Card Skimming Scheme

Cybercriminals are using a new variation of a common credit card skimming attack. Messaging app Telegram is being exploited as a gate to exfiltrate the stolen payment card numbers and customer details. The stolen data is skimmed from eCommerce websites that are compromised by malware. The shopper does not notice anything strange during the checkout process. The website owner is usually unaware that something has infected their online checkout.

In this scheme payment details including card numbers, customer name, address, credit card number, expiry, and security code (CVV) are posted on a private Telegram channel as an instant message.

“Unaware shoppers may visit a merchant that has been compromised with a web skimmer and make a purchase while unknowingly handing over their credit card data to criminals,” says a report by cyber security researchers at Malwarebytes.
