A simple tool to inject shellcode into an ELF binary.
- gcc
- A ELF binary (no PIE)
How to install
git clone https://github.com/njord0/elfwizard
cd elfwizard
gcc -o elfwizard src/* -Iincludes/
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
