go-embed-extractor

go-embed-extractor is a lightweight Go tool for extracting files embedded in Go binaries using the embed package. It provides a simple way for developers and reverse engineers to analyze and recover embedded static resources, such as HTML, CSS, images, or other files.

Features

• Extract embedded files from Go binaries.
• Supports multiple architecture files (MachO, ELF, PE).
• Option to save extracted files to a specified directory.

Basic Usage

1. Use some decompilation tools to obtain the embed.FS structure virtual address.

@leonjza shared a method to locate FS structure pointers using radare, and then extract embedded files with go-embed-extractor.

2. Extract embedded files from a Go binary:

gee -target -target ./tests/embedemo_macho -vaddr 0x00000001000EAA00
