information about Apple MachO files.

macho_info returns information about Apple MachO file format. Tt is a list, with items for every 'app' contained, each item of the list contains the following attributes:

  • commands: <list of dictionaries> list of load commands. Every entry contains the following fields:
    • type: <string> command type.
  • headers: <dictionary> some descriptive metadata about the file.
    • cpu_subtype: <string> processor subtype (i.e. "I386_ALL").
    • cpu_type: <string> general type of processor (i.e. "i386").
    • file_type: <string> file type (i.e. "dynamically bound shared library").
    • flags: <list of strings> file flags (i.e. "DYLDLINK", "NOUNDEFS").
    • magic: <string> magic identifier of this app in hex format.
    • num_cmds: <integer> number of commands.
    • size_cmds: <integer> commands size.
  • libs: <list of strings> libraries used by the file.
  • segments: <list of dictionaries> list of segments of the file. Every entry contains the following fields:
    • fileoff: <string> segment phisical address in hex format.
    • filesize: <string> segment size in hex format.
    • name: <string> segment name.
    • sections: <list of dictionaries> sections of the segment. Every entry contains the following fields:
      • flags: <list of strings> section flags (i.e. "S_8BYTE_LITERALS").
      • name: <string> section name.
      • type: <string> section type.
    • vmaddr: <string> virtual address in hex format.
    • vmsize: <string> virtual address size in hex format.
