"Cryptocurrencies malware based detection
Patent number: 11128647
Abstract: A computer implemented method to identify a computer security threat based on communication of a network connected device via a computer network including receiving a plurality of blocks of network traffic from the device, each block including a sequence of network traffic data items being identifiable by a position in the sequence of the block; identifying a subset of positions occurring in every block for which a degree of variability of values of data items in each position of the subset meets a predetermined threshold; and generating executable code for performing a plurality of processing operations based on the identified subset of positions, the executable code consuming a determinate quantity of computing resources when executed for the received network traffic.
