RAGG2-CC(1) BSD General Commands Manual RAGG2-CC(1) 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 ", 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 e90000000083ec0ce800000000588d882a000000b804000000606a0651 6a0150cd8083c41061b8010000006a0050cd8083c40883c40cc368656c 6c6f0a00 # Use a xor encoder with key 32 to bypass $ ragg2 -e xor -c key=32 -B `ragg2-cc -x hi.c` 6a3e596a205be8ffffffffc15e4883c60d301e48ffc6e2f9c920202020 a3cc2cc82020202078ada80a2020209824202020404a26714a2170eda0 a3e4304198212020204a2070eda0a3e428a3e42ce348454c4c4f2a20 SEE ALSO
