Systems, apparatuses, methods, and computer programs for detecting anomalies to identify coordinated group attacks on computer networks are provided. An anomaly graph of a network including nodes, edges, and an indegree of the nodes in the anomaly graph may be determined. Nodes with an indegree of at least two may be designated as potential targets. Nodes with no incoming connections may be designated as potentially compromised nodes. The designated potentially compromised nodes may be outputted as potentially associated with a coordinated attack on the network when the potentially compromised nodes connect to one or more of the same potential target nodes.
