It took a while to find the original, it's a PDF rather than a web page and it was plagiarized within days of being published, google picked up on the plagiarized copy before it ever saw the original by the looks of it.
I am not sure how you get from the PDF to the confirmation. The first page of the PDF says it is from “Infosec Institute” and “Darmawan Salihun”. If you want to show plagiarism, should you not be linking to a version that has the same contents but with different authors?
