Abstract
An apparatus and method of diagnosing whether a computer program executed in a computer system is a malicious program and more particularly, an apparatus and method of diagnosing whether a computer program is a malicious program using a behavior of a computer program, and an apparatus and method of generating malicious code diagnostic data is provided. The apparatus for diagnosing a malicious code may include a behavior vector generation unit which generates a first behavior vector based on a behavior signature extracted from a diagnostic target program; a diagnostic data storage unit which stores a plurality of second behavior vectors for a plurality of sample programs predetermined to be malicious or normal; and a code diagnostic unit which diagnoses whether the diagnostic target program is a malicious code by comparing the first behavior vector with the plurality of second behavior vectors.
