DETECTING MAN-IN-THE-MIDDLE ATTACKS IN ELECTRONIC TRANSACTIONS USING PROMPTS

Aspects of the invention provide a solution for detecting man-in-the-middle attacks in electronic transactions using prompts. One embodiment includes a method for authenticating an electronic transaction. The method includes: receiving an electronic transaction request from a user, determining an IP address associated with a client system from which the electronic transaction request originates, providing the user with a password associated with the electronic transaction request, receiving a telephonic communication from a telephonic device associated with the user, prompting the user, via a voice response unit, to input the password using the telephonic device, authenticating the user by comparing the inputted password and the provided password, determining a probable location of the user based on the determined IP address of the client system, communicating to the user the probable location of the user based on the determined IP address, and prompting the user to confirm the probable location of the user.
