NAME
ragg2-cc - CC frontend for compiling shellcodes
SYNOPSIS
ragg2-cc [-a arch] [-b bits] [-k kernel] [-o file] [-dscxvh]
DESCRIPTION
ragg2-cc is a frontend of CC. It is used to creates tiny binaries (1KB) or shellcodes in
binary or hexpairs from a C source.
The compiler used is the one configured by the CC environment. This has been tested with
gcc, llvm-gcc and clang.
Uses sflib (shellforge4) includes to get the syscall definitions.
Only linux/darwin x86-32/64 is supported at the moment. Planned support for more
architectures.
OPTIONS
-a arch set architecture x86, arm
-b bits 32 or 64
-k kernel windows, linux or osx
-o file output file to write result of compilation
-h show help message
-v show version
-d show assembler code
-s generate assembly file
-c generate compiled shellcode
-x show hexpair bytes
EXAMPLE
$ cat hi.c
int main() {
write (1, "Hello World\n", 12);
exit (0);
}
$ ragg2-cc hi.c
hi.c.bin
# Linked into a tiny binary. This is 294 bytes
$ wc -c < hi.c.bin
294
$ ./hi.c.bin
Hello World
# The compiled shellcode has zeroes
$ ragg2-cc -x hi.c
