fnprint

fnprint is a binary analysis tool that uniquely identifies functions in stripped executables by analyzing their behavioral side effects rather than relying on byte signatures or control-flow graphs. It emulates function execution with fabricated inputs to generate behavior-based fingerprints, allowing for more resilient matches across different compiler optimizations and versions. Key features include indexing known binaries for function identification, differential analysis to detect behavioral changes between builds, and a triage capability to assess potential vulnerabilities based on function behavior comparison.
