FASER

FASER is a tool designed for cross-architecture binary code similarity search, leveraging Binary Intermediate Representations to identify functions of interest in software, which is particularly useful for malware analysis, software supply chain security, and vulnerability research. Notable features include its ability to operate without manual feature engineering or dynamic analysis, as well as demonstrating superior performance in both general function search and targeted vulnerability search tasks compared to baseline methods. The tool utilizes long document transformers to enhance the effectiveness of its search capabilities.
