FLIRT Signatures & Library Function Identification

Automatically recognize statically-linked library code so your scripting focuses only on the application's real logic.

The Library Noise Problem

You can script disassemblers, automate structure recovery, and patch binaries. But statically-linked programs bundle thousands of library functions (libc, the C++ STL, runtime).

Wading through them by hand wastes enormous time.

Static Linking Inlines Libraries

When a binary is statically linked, library code is copied directly into the executable. There are no import names; printf just looks like another anonymous function.

Identifying these frees you to focus on the author's own code.
