1. Prepare your payload in payload.nasm file or you can directly specify it in make.sh script (PAYLOADCODE= variable)
|
|
|
|
I'm using a symlink as follows
|
|
|
|
exam3$ ln -svf payload-execve-stack.nasm payload.nasm
|
|
`payload.nasm' -> `payload-execve-stack.nasm'
|
|
|
|
2. Compile the shellcode with a custom "egg" (must be 8 bytes in length)
|
|
|
|
exam3$ ./make.sh "cust.egg"
|
|
[I] Using custom EGG mark: cust.egg
