Query: Outflanking and securely using the PIN/TAN-System   The PIN/TAN-system is an authentication and authorization scheme used in
e-business. Like other similar schemes it is successfully attacked by
criminals. After shortly classifying the various kinds of attacks we accomplish
malicious code attacks on real World Wide Web transaction systems. In doing so
we find that it is really easy to outflank these systems. This is even
supported by the users' behavior. We give a few simple behavior rules to
improve this situation. But their impact is limited. Also the providers support
the attacks by having implementation flaws in their installations. Finally we
show that the PIN/TAN-system is not suitable for usage in highly secure
applications.
