A new research paper explores the vulnerability of large language models (LLMs) to "role spoofing," a type of prompt injection where malicious text can impersonate a user by mimicking their writing style or formatting. The study, "Understanding and Mitigating Role Spoofing in LLMs," reveals that LLMs rely on both content and structural cues to track conversational roles, making them susceptible to attacks that combine fake structure and content. While adversarial training can help against content-based attacks, it leaves models vulnerable to structure-based impersonation. The researchers propose a detection method using linear probes to identify role spoofing across different conversational settings. AI
