This evening (Monday 26th October 2009, at 19:30 UTC), BBC Inside Out will show Saar Drimer and I demonstrating how the use of smart card readers, being issued in the UK to authenticate online banking transactions, can be circumvented. The programme will be broadcast on BBC One, but only in the East of England and Cambridgeshire, however it should also be available on iPlayer.
In this programme, we demonstrate how a tampered Chip & PIN terminal could collect an authentication code for Barclays online banking, while a customer thinks they are buying a sandwich. The criminal could then, at their leisure, use this code and the customer’s membership number to fraudulently transfer up to £10,000.
Similar attacks are possible against all other banks which use the card readers (known as CAP devices) for online banking. We think that this type of scenario is particularly practical in targeted attacks, and circumvents any anti-malware protection, but criminals have already been seen using banking trojans to attack CAP on a wide scale.
