These are the fields generated by the file_integrity module.
File attributes.
These fields contain Linux Executable Linkable Format (ELF) metadata.
-
file.elf.go_imports -
List of imported Go language element names and types.
type: flattened
-
file.elf.go_imports_names_entropy -
Shannon entropy calculation from the list of Go imports.
type: long
format: number
-
file.elf.go_imports_names_var_entropy -
Variance for Shannon entropy calculation from the list of Go imports.
type: long
format: number
-
file.elf.go_import_hash -
A hash of the Go language imports in an ELF file excluding standard library imports. An import hash can be used to fingerprint binaries even after recompilation or other code-level transformations have occurred, which would change more traditional hash values. The algorithm used to calculate the Go symbol hash and a reference implementation are available [here](https://github.com/elastic/toutoumomoma).
type: keyword
example: 10bddcb4cee42080f76c88d9ff964491
-
file.elf.go_stripped -
Set to true if the file is a Go executable that has had its symbols stripped or obfuscated and false if an unobfuscated Go executable.
