Abstract
A method includes (a) collecting information on times at which domains were contacted by each device of a set of devices on a network, (b) for each domain contacted by the set of devices, recording a list of time gaps between subsequent contacts to that domain by each device, (c) for each domain, calculating an entropy for the list of time gaps for that domain, a lower entropy indicating that that domain has been accessed at more regular intervals, while a higher entropy indicates that that domain has been accessed at more random intervals, (d) selecting a subset of the set of domains having smaller entropies relative to other domains of the set of domains, and (e) presenting the selected subset to an administrator with directions to review domains of the subset for potential contact with malware installed on devices of the computer network.
