elfcat - ELF visualizer. Generates HTML files from ELF binaries.

  1. How do I install and use it?

    $ cargo install elfcat
$ elfcat path/to/file

  2. What does it look like?

    This is what the following small example ELF file looks like:

    http://ruslashev.github.io/elfcat/hello_world.html

    Steps to create it:

    $ cat hello_world.s
global _start

section .text
_start:
    mov rax, 1
    mov rdi, 1
    mov rsi, msg
    mov rdx, len
    syscall

    mov rax, 60
    xor rdi, rdi
    syscall

section .data
    msg db "Hello, world!", 0xA
    len equ $ - msg

$ cat link.ld
ENTRY(_start)

SECTIONS {
    . = 0x10080; /* vm.mmap_min_addr + p_offset of first segment */

    .text : {
        * (.text)
    }

    .data : {
        * (.data)
    }
}

$ nasm hello_world.s -f elf64
$ ld hello_world.o -o hello_world -n -T link.ld
$ elfcat hello_world
$ xdg-open hello_world.html
