Where they got that script?

I am planning to start an affiliate site on Movie. When I google for research I found some domain which use the same script:

oncima.com
95movp.com
watchmovies4k.vip
iasneg.blogspot.com

Can anyone help me to find the script? Which script they are using and which affiliate program you are using?

Thanks in advance
