Today’s Focus: Prompt Injection in Healthcare

The OWASP Top 10 for Large Language Models (LLMs) highlights Prompt Injection (LLM01) as a critical risk. In the healthcare industry, this vulnerability can have devastating consequences.

The Threat

Prompt injection occurs when an attacker provides specifically crafted input that tricks the LLM into ignoring its original instructions and following the attacker’s commands instead.

Industry Impact: Healthcare

• Medical Misinformation: An LLM used for patient triage or medical advice could be manipulated to suggest harmful treatments or incorrect drug dosages.
• Patient Privacy Violations: By exploiting prompt injection, attackers might bypass security filters to extract sensitive Patient Health Information (PHI) stored in the model’s context or accessible through tools.
• Systemic Disruption: If the LLM is connected to EHR (Electronic Health Record) systems, an injection could lead to the unauthorized modification of patient histories or medical schedules.

Conclusion

As healthcare increasingly relies on LLMs for efficiency, robust input validation and strict instruction adherence are paramount to protecting patient safety and privacy.
