If I wanted access to an article or book to reference in a university essay, would I face disciplinary action if i used these two websites to access the material

sci-hub.se

http://gen.lib.rus.ec/

Suppose all i did was just cite the article and gave no indication where i accessed it. Would they know I used scihub/libgen and invalidate my work?
No i won't use university wi-fi to access the pages and if i did I'd use a proxy.
