Claim One:
1. A method comprising: processing input data to derive a set of features for each user account or event for a plurality of user accounts; generating a set of feature profiles, each feature profile having a set of features derived from a profile constructed from a set of correlated events or a set of correlated user accounts; generating hypergraphs, wherein the hypergraphs include nodes corresponding to feature profiles and edges between particular nodes representing a measure of similarity between nodes, wherein the measure of similarity between a pair of nodes is based at least in part on a comparison of a plurality of feature values associated with each node of the pair of nodes and weighting the edges based on the comparison; using the generated hypergraphs to detect suspicious graph nodes based on the respective feature profiles of each graph node and a global feature profile; using the suspicious graph nodes to detect malicious graph communities; and using the malicious graph communities to determine whether a particular user account is likely to correspond to a malicious user.
