I am a professional scripter, specially with python, I've been before on projects in this nature, specifically a backdoor undetected by the firewall, IPS, and antivirus and antimalware, crossplatform(linux and windows) that collects data and gives access to shell and upload and download, cam, pretty much everything. I am familiar with the Exlpoit that you need, I work on Kali Linux, metasploit on .docx and .pdf. I assure you that the script would be lit!
