Indirect Prompt Injection Attacks Observed in the Wild

Analysis of real-world telemetry reveals that indirect prompt injection (IDPI) attacks are no longer theoretical but are actively being weaponized. These attacks exploit benign features like webpage summarization or content analysis to cause LLMs to unknowingly execute attacker-controlled prompts. Observed attacker intents include AI-based ad review evasion, SEO manipulation promoting phishing sites, data destruction, denial of service, unauthorized transactions, sensitive information leakage, and system prompt leakage. Researchers identified 22 distinct techniques used by attackers to create IDPI payloads. Mitigating web-based IDPI requires proactive, web-scale capabilities to detect IDPI, distinguish benign and malicious prompts, and identify underlying attacker intent. Palo Alto Networks customers are better protected from these threats through their products and services. The Unit 42 AI Security Assessment can help empower safe AI use and development.
