Details

According to an investigation by GPTZero, the cybersecurity report 'Points of Attack' published by EY Canada was found to be seriously contaminated by LLM hallucinations.

The main issues are as follows:

  • Vibe Citing: Most of the URLs in the resource table included in the report are invalid or fake, and more than half of the source titles refer to materials that don't actually exist.
  • Signs of AI Generation: Text analysis suggests the content was AI-generated, containing numerous typical LLM errors such as fake statistics, incorrect citations, and internal contradictions.

GPTZero warned that this kind of 'vibe citing' phenomenon is being observed not only at consulting firms but also at prestigious AI conferences such as NeurIPS and ICLR. This poses a serious threat as false information spreads through news, blogs, and AI search engines, undermining research quality and public trust.
