One or more computing devices, systems, and/or methods for detecting spoofing attacks are provided. Location information of a base station may be evaluated to determine a true position of the base station. Satellite signals received by the base station may be processed and evaluated to calculate a real time position of the base station. A distance between the real time position and the true position may be calculated. In response to the distance exceeding a threshold distance, an alert is generated to indicate that the base station is experiencing a spoofing attack.
