For each of your task, you have to implement separate algorithm for check.

  • Check extension before upload (see possible duplicate question)
  • Check that uploaded zip is really an archive (mime type, libmagic, etc)
  • Check that uploaded archive doesn't contain exe (unzip it, see previous paragraph)
