Creating Android Malware Knowledge Graph Based on a Malware Ontology

As mobile and smart connectivity continue to grow, malware presents a permanently evolving threat to different types of critical domains such as health, logistics, banking, and community segments. Different types of malware have dynamic behaviors and complicated characteristics that are shared among members of the same malware family. Malware threat intelligence reports play a crucial role in describing and documenting the detected malware, providing a wealth of information regarding its attributes, patterns, and behaviors. There is a large amount of intelligent threat information regarding malware. The ontology allows the systematic organization and categorization of this information to ensure consistency in representing concepts and entities across various sources. In this study, we reviewed and extended an existing malware ontology to cover Android malware. Our extended ontology is called AndMalOnt. It consisted of 13 new classes, 16 object properties, and 31 data properties. Second, we created an Android malware knowledge graph by extracting reports from the MalwareBazaar repository and representing them in AndMalOnt. This involved generating a knowledge graph that encompasses over 2600 malware samples. Our ontology, knowledge graph, and source code are all open-source and accessible via GitHub
