An Empirical Study of Privacy Leakage Chains via Prompt Injection in Black-Box Chatbot Environments
Researchers have developed a new method called 'exemplification' to exploit privacy vulnerabilities in black-box chatbot environments. This technique allows attackers to hijack an agent's intended task by crafting seemingly benign external content that redirects the chatbot to execute malicious objectives. The study demonstrates a data-exfiltration chain by combining prompt injection, instruction steering, and web-tool invocation, highlighting a feasible privacy-leakage path in deployed chatbot agents.
