Abstract
A cybersecurity server receives an executable file to be classified. A call graph of the executable file is generated. Functions of the executable file are represented as vertices in the call graph, and a vertex value is generated for each vertex. The vertex values are arranged in traversal order of the call graph to generate a call graph pattern. A digest of the call graph pattern is calculated and compared to one or more malicious digests.
