eh??
"They allegedly exploited a vulnerability to break into the company's network, where they retrieved payment card data as it was being processed." --- 2 issues with this, firstly how did they break in? Surely RBS Worldpay are PCI compliant so they should have adequate security controls in place to protect against these kind of attacks. If RBS Worldpay were PCI compliant and still got hacked, this places a big question mark over the worth and effectiveness of PCI compliance. Secondly, how did the intruders get the PIN numbers? PIN numbers are never (or at least should not be) stored or transmitted in clear text anywhere on a Banks network. So how did they obtain them?? All sounds a bit hazy on the details to me...
