ElfWizard

A simple tool to inject shellcode into an ELF binary.

Requirements

• gcc
• A ELF binary (no PIE)

Installation

How to install

git clone https://github.com/njord0/elfwizard
cd elfwizard
gcc -o elfwizard src/* -Iincludes/

Examples

Code injection on 64 bits binary

I will use test/test.c for this example,
first we need to compile the binary:

gcc -o test.bin test/test.c -fno-pie -no-pie

We are now ready to inject the shellcode, I wrote a simple shellcode that prints "Hello world". (Here)

./elfwizard --inject 4831c050b8726c640a5048b848656c6c6f20776f50b801000000bf010000004889e6ba0d0000000f05 test.bin

Now we can execute the binary :

$ ./test.bin
Hello world
A simple program that display his name and PID
test.bin : 49686

Code injection on 32 bits binary

I will use test/test.c for this example,
first we need to compile the binary:

gcc -o test.bin test/test.c -fno-pie -no-pie -m32

We are now ready to inject the shellcode, I wrote a simple shellcode that prints "Hello world". (Here)

./elfwizard --inject 31c05068726c640a686f20776f6848656c6c89e1b804000000bb01000000ba0c000000cd80 test.bin

Now we can execute the binary :

$ ./test.bin
Hello world
A simple program that display his name and PID
test.bin : 51237
