ropper
This package contains scripts that display info about files in different formats and find gadgets to build ROPs chains for different architectures (x86/x86_64, ARM/ARM64, MIPS, PowerPC). For disassembly ropper uses the Capstone Framework.

You can use ropper to display information about binary files in different file formats
and you can search for gadgets to build rop chains for different architectures
supported filetypes:
ELF
PE
Mach-O
Raw
supported architectures:
x86 [x86]
x86_64 [x86_64]
MIPS [MIPS, MIPS64]
ARM/Thumb [ARM, ARMTHUMB]
ARM64 [ARM64]
PowerPC [PPC, PPC64]
SPARC [SPARC64]
available rop chain generators:
execve (execve[=<cmd>], default /bin/sh) [Linux x86, x86_64]
mprotect (mprotect address=0xdeadbeef size=0x10000) [Linux x86, x86_64]
virtualprotect (virtualprotect address=0xdeadbeef) [Windows x86]
optional arguments:
-h, --help show this help message and exit
-v, --version Print version
--console Starts interactive commandline
-f <file> [<file> ...], --file <file> [<file> ...]
The file to load
-r, --raw Loads the file as raw file
-a <arch>, --arch <arch>
The architecture of the loaded file
--section <section> The data of the this section should be printed
--string [<string>] Looks for the string <string> in all data sections
--hex Prints the selected sections in a hex format
--asm [<asm> [H|S|R] ...]
A string to assemble and a format of the output
(H=HEX, S=STRING, R=RAW, default: H)
--disasm <opcode> Opcode to disassemble (e.g. ffe4, 89c8c3, ...)
--disassemble-address <address:length>
Disassembles instruction at address <address>
(0x12345678:L3). The count of instructions to
disassemble can be specified (0x....:L...)
-i, --info Shows file header [ELF/PE/Mach-O]
-e Shows EntryPoint
--imagebase Shows ImageBase [ELF/PE/Mach-O]
-c, --dllcharacteristics
Shows DllCharacteristics [PE]
-s, --sections Shows file sections [ELF/PE/Mach-O]
-S, --segments Shows file segments [ELF/Mach-O]
--imports Shows imports [ELF/PE]
--symbols Shows symbols [ELF]
--set <option> Sets options. Available options: aslr nx
--unset <option> Unsets options. Available options: aslr nx
-I <imagebase> Uses this imagebase for gadgets
-p, --ppr Searches for 'pop reg; pop reg; ret' instructions
[only x86/x86_64]
-j <reg>, --jmp <reg>
Searches for 'jmp reg' instructions (-j reg[,reg...])
[only x86/x86_64]
--stack-pivot Prints all stack pivot gadgets
--inst-count <n bytes>
Specifies the max count of instructions in a gadget
(default: 6)
--search <regex> Searches for gadgets
--quality <quality> The quality for gadgets which are found by search (1 =
best)
--opcode <opcode> Searchs for opcodes (e.g. ffe4 or ffe? or ff??)
--instructions <instructions>
Searchs for instructions (e.g. "jmp esp", "pop eax;
ret")
--type <type> Sets the type of gadgets [rop, jop, sys, all]
(default: all)
--detailed Prints gadgets more detailed
--all Does not remove duplicate gadgets
--cfg-only Filters out gadgets which fail the Microsoft CFG
check. Only for PE files which are compiled with CFG
check enabled (check DllCharachteristics) [PE]
--chain <generator> Generates a ropchain [generator parameter=value[
parameter=value]]
-b <badbytes>, --badbytes <badbytes>
Set bytes which should not contains in gadgets
--nocolor Disables colored output
--clear-cache Clears the cache
--no-load Don't load the gadgets automatically when start the
console (--console)
--analyse <quality> just used for the implementation of semantic search
--semantic constraint
semantic search for gadgets
--count-of-findings <count of gadgets>
Max count of gadgets which will be printed with
semantic search (0 = undefined, default: 5)
--single No multiple processes are used for gadget scanning
