A Codeless PE Binary File That Runs!!!

Recently, I came across article written in alex lonescu's blog. Its about the PE tricks that PE binary which having no codes.
As per his words:

the challenge is - "Write a portable executable (PE/EXE) file which can be spawned through a standard CreateProcess call and will result in STATUS_SUCCESS being returned as well as a valid Process Handle, but will not
  • Contain any actual x86/x64 assembly code section (i.e.: the whole PE should be read-only, no +X section)
  • Run a single instruction of what could be construed as x86 assembly code, which is part of the file itself (i.e.: random R/O data should not somehow be forced into being executed as machine code)
  • Crash or make any sort of interactive/visible notice to the user, event log entry, or other error condition."

He did it.
