File Integrity fields
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.
