HiGraph is a large-scale hierarchical graph dataset for Android malware analysis. It contains 499,981 Android applications (50,661 malicious and 449,320 benign), where each application is represented by a two-level hierarchical structure combining Function Call Graphs (FCGs) and over 200 million embedded Control Flow Graphs (CFGs). The dataset spans 683 malware families collected between January 2012 and December 2022, enabling research on malware detection and classification, robustness to code obfuscation, and temporal evolution analysis of malware. Data and code are released under CC BY-NC-SA 4.0.
