Abstract:
1. A computer-implemented method for adjusting suspiciousness scores in event-correlation graphs, at least a portion of the method being performed by a computing device comprising at least one processor, the method comprising: detecting a suspicious event involving a first actor and a second actor within a computing system, wherein the suspicious event could not be individually classified as definitively malicious; constructing, after the suspicious event involving the first actor and the second actor is detected, an event-correlation graph, wherein the event-correlation graph comprises at least: adjusting a suspiciousness score associated with at least one of an actor represented in the event-correlation graph and a suspicious event represented in the event-correlation graph based at least in part on a suspiciousness score associated with at least one other actor or suspicious event represented in the event-correlation graph such that the adjusted suspiciousness score is influenced by the suspiciousness score associated with the at least one other actor or suspicious event.
