An apparatus for detecting an attack on an electric circuit, wherein the electric circuit includes a current consumption threshold value discriminator to determine whether current consumption of the electric circuit exceeds a predetermined threshold value or not, and to generate a binary current limitation signal depending therefrom. The apparatus includes a monitor for monitoring the binary current limitation signal over a predetermined time interval, in order to indicate a signal characterizing the current consumption of the electric circuit over the predetermined time interval, and a detector for detecting an attack on the electric circuit based on the monitoring signal.
