Abstract

The banking industry in Norway has developed a new security infrastructure for conducting commerce on the Internet. The initiative, called BankID, aims to become a national ID infrastructure supporting services such as authentication and digital signatures for the entire Norwegian population. This paper describes a practical man-in the- middle attack against online banking applications using BankID. The attack gives an adversary access to customer bank accounts in two different online banking systems. Proof of concept code has been developed and executed to demonstrate the seriousness of the problem.
