More than 26 million debit and credit cards have been stolen for a second time from a marketplace called BriansClub which deals with stolen card data.
It is reported that the card details had initially been stolen from high street retailers over the past four years, including 8 million stolen in 2019.
Criminals can potentially use the data to create fake magnetic-strip cards with which to buy items in-store. Although the roll-out of chip and PIN cards is intended to put an end to this practice, there are still enough retailers and cardholders using the older-style cards to make carding forums, where stolen details can be bought, a going concern.
Those affected by data breaches and the theft of card details should be vigilant against any suspicious activity on their bank accounts and credit cards and contact their bank with any concerns.
