Researchers have discovered a vulnerability in OpenAI's Connectors that allows attackers to extract sensitive information from Google Drive using a single poisoned document. This attack highlights the risks associated with connecting AI models to external services and underscores the importance of robust security measures against prompt injection attacks.
A single poisoned document can be used to extract sensitive information from ChatGPT using a weakness in OpenAI's Connectors. An indirect prompt injection attack allows attackers to trick the system into completing malicious actions. A vulnerability was demonstrated at the Black Hat hacker conference, where researchers shared a proof of concept video showing how an attacker can extract developer secrets from a Google Drive account. Users are vulnerable to attack without even realizing it, simply by using AI services that connect to external services. The discovery emphasizes the importance of robust protections against prompt injection attacks and highlights the risks associated with connecting AI models to external services.
In recent times, the world of artificial intelligence (AI) has seen an explosion of advancements and innovations that have transformed numerous aspects of our lives. However, with these rapid developments come significant concerns regarding the security and safety of these systems. In a shocking revelation, researchers have demonstrated how a single poisoned document can be used to extract sensitive information from ChatGPT, highlighting the vulnerabilities in OpenAI's Connectors that allow users to link their AI models to external services.
The discovery was made by Michael Bargury, a senior researcher at Zenity, and Tamir Ishay Sharbat, a security expert. In a presentation at the Black Hat hacker conference in Las Vegas, they revealed how a weakness in OpenAI's Connectors allowed them to extract data from a Google Drive account without any user interaction. This attack is known as an indirect prompt injection attack, where attackers feed an LLM (large language model) poisoned data that can trick the system into completing malicious actions.
Bargury and Sharbat used a process called "AgentFlayer" to demonstrate this vulnerability. They shared a poisoned document with a potential victim's Google Drive account, which contained a 300-word malicious prompt hidden in white text in a size-one font. This prompt was written in such a way that it would not be visible to humans but could still be read by machines.
In the proof of concept video, Bargury showed how the victim asked ChatGPT for "summarize my last meeting with Sam." However, instead of summarizing the actual content of the meeting, the system extracted developer secrets – in this case, API keys stored in a demonstration Drive account. These API keys could have been used to gain unauthorized access to sensitive information and potentially compromise other systems.
This vulnerability highlights the risks associated with connecting AI models to external services and sharing data across them. Bargury noted that "there is nothing the user needs to do to be compromised, and there is nothing the user needs to do for the data to go out." This means that users are vulnerable to attack without even realizing it, simply by using their services.
Bargury reported this finding to OpenAI earlier in the year, and the company quickly introduced mitigations to prevent this technique from being used. However, the discovery emphasizes the importance of robust protections against prompt injection attacks. Andy Wen, senior director of security product management at Google Workspace, pointed out that "while this issue isn't specific to Google, it illustrates why developing strong security measures is essential for protecting AI systems."
The revelation also raises questions about the long-term implications of connecting AI models to external services. Bargury noted that while this feature increases the utility and power of AI, it also comes with significant risks.
In conclusion, the discovery of a single poisoned document being used to extract sensitive information from ChatGPT highlights the vulnerabilities in OpenAI's Connectors and the importance of robust security measures against prompt injection attacks. As AI continues to advance and become increasingly integrated into our lives, it is crucial that we prioritize security and develop effective countermeasures to protect these systems.
