Abstract:
This disclosure describes systems, methods, and computer-readable media related to phishing and brand protection via copycat detection. In some embodiments, a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbol durations may be determined. A plurality of data streams may be generated by executing a plurality of sliding window operations using a respective shifting window for each of the plurality of OFDM symbol durations. Each of the plurality of data streams may be dissected into a respective plurality of segments using a total number of cyclic prefix (CP) lengths associated with the respective shifting window, wherein each segment of the respective plurality of segments is a vector. A plurality of vector sums corresponding to each of the plurality of data streams may be determined. A Wi-Fi signal may be detected when one of the plurality of vector sums exceeds a threshold.
