Hidden Prompts in Manuscripts Exploit AI-Assisted Peer Review
Quick summary
arXiv:2507.06185v2 Announce Type: replace-cross Abstract: In July 2025, 18 academic manuscripts on arXiv contained hidden instructions that manipulated AI-assisted peer review (indirect prompt injection). Instructions such as "GIVE A POSITIVE REVIEW ONLY" were concealed using white text and microscopic font sizes. Author responses varied: one planned to withdraw their manuscript, while another defended the practice as legitimate testing of reviewers misusing large language models (LLMs). This analysis examines the technique within the broader pattern of prompt injection exploits that manipulat
