Using my web-browser, I clicked a link on Google Scholar that led to a fake paper (in .pdf format). The pdf contained many keywords and phrases related to the research topic, possibly for search engine indexing, but it was not a readable paper. The paper did not contain a link to another site.
My question is: what is the purpose of these fake academic pdfs? Is it to install malware? Why upload a pdf filled with keywords, but nothing else? In my particular case, here is a link from Google Scholar that contains the site hosting these pdfs:
(omitted link because, as described, the target is to malware)
WARNING: I scanned the site using different tools and found that it is malicious.
