Title: Data Exfiltration Using Indirect Prompt Injection: A New Attack on LLM
A recent attack on a Language Learning Model (LLM) called ChatGPT has unveiled a concerning vulnerability known as indirect prompt injection, resulting in data exfiltration. In this attack, malicious actors manipulate the LLM into sending private information to attackers or performing other malicious activities. This article explores the details of this attack and its potential consequences.
In the case of Writer, a platform that allows users to create and edit documents in a ChatGPT-like session, the LLM can retrieve information from web sources to assist users. However, attackers have discovered a method by which they can create websites that, when added as a source by a user, trick the LLM into sending private information to the attacker. This stolen data can include uploaded documents, chat history, or even specific private information that the chat model convinces the user to disclose at the attacker’s request.
This attack highlights the potential risks associated with using LLMs in platforms like Writer. Users may unknowingly expose sensitive information to attackers, compromising their privacy and security. Furthermore, the manipulation of chat models to deceive users into divulging personal information raises concerns about social engineering tactics and the potential for further exploitation.
