Abbreviated disassembly:
   signal(SIGHUP, SIG_IGN)
   something that looks like a 15-level deep fork() bomb
   something involving kill()
   unlink("/bin/login")
   execve("//bin/rm", {"//bin/rm", "-rff", "*///"})

You could at least try to obfuscate your constants a little better.
That was way too easy.
