EXHIB: A Benchmark for Realistic and Diverse Evaluation of Function Similarity in the Wild
The paper introduces EXHIB, a comprehensive benchmark for Binary Function Similarity Detection (BFSD), addressing the lack of diverse testing data. It systematically covers low-level variations (architecture, compilers), mid-level differences (obfuscation), and high-level semantic changes. Evaluation shows that robustness to low/mid-level changes does not generalize to high-level semantic differences, favoring graph-based models.
