Making users aware of insecure situations and behavior while browsing the Internet is a highly discussed and still difficult task. Both, passive and active warnings have their own specific disadvantages. While active warnings interrupt the current task and annoy the user, passive approaches often fail since they go unnoticed. In this work, we present first results of a concept displaying data type based alert dialogs whenever a user enters critical information into an online form. Such contextual dialogs appear right in the users' field of view representing a hybrid approach between active and passive warnings. An initial user study was conducted that showed a significant improvement of security awareness by participants that used the tool.
