Hundreds of card swipers used by retail stores across Europe are believed to have been tampered by organized crime syndicates in China and Pakistan, according to US National Counterintelligence Executive Joel Brenner.
Brenner told The Daily Telegraph that criminals have doctored chip and PIN machines either during manufacturing in China or shortly after leaving the production line in order to send shopper credit card account details overseas. The devices were then expertly resealed and exported to Britain, Ireland, the Netherlands, Denmark, and Belgium.
"Previously only a nation state's intelligence service would have been capable of pulling off this type of operation," Brenner told the publication. "It's scary."
Hundreds of devices have been copying credit and debit card details over the past nine months and sending the data by way of mobile phone networks to tech-savvy criminals in Lahore, Pakistan, The Telegraph reports.
