I'm not a professor, but something similar recently happened to me.
A conference abstract I did write was entirely rephrased and assigned a full reference, including DOI, pages, and the name of a real journal. On journal website, which is from a different field btw, my "article" is or course absent.

A network of fake academic journals masquerading as legitimate publications has published more than a hundred AI-generated papers in recent months, in some cases using the names of real professors at top universities without their knowledge.
Online academic journals falsely attributed articles, likely written by AI, to several professors, who say the fiasco is a warning about the future of scientific knowledge.
