A major security flaw in the popular language model ChatGPT has been discovered by a group of academics from prestigious universities, including Google DeepMind, the University of Washington, Cornell, Carnegie Mellon University, the University of California Berkeley, and ETH Zurich. The researchers stumbled upon this vulnerability while testing the chatbot’s capabilities, leading to unintended disclosure of personal data, including phone numbers and email addresses, in response to seemingly harmless requests.
In their investigation, the researchers found that by instructing ChatGPT to repeat random words indefinitely, the chatbot inadvertently revealed sensitive information from its training set. This included personal contact details, snippets from research papers, news articles, Wikipedia pages, and more. The researchers published their findings in a paper on Tuesday, highlighting the potential security risks associated with large language models like ChatGPT.
The incident raises concerns about the security of AI models and the necessity for thorough testing before their deployment in real-world applications. The researchers expressed surprise at the success of their attack and stressed the importance of early detection and continuous vigilance to prevent such vulnerabilities.
ChatGPT and similar language models that power AI services like chatbots and image generators heavily rely on extensive training data. However, the specific sources of data used for OpenAI’s chatbot have not been disclosed due to the closed-source nature of the underlying models.
The researchers discovered that certain specific prompts caused ChatGPT to reveal personally identifiable information (PII) at an alarming rate. For instance, requesting the chatbot to repeat the word poem resulted in the disclosure of a real founder and CEO’s email address and cellphone number. The vulnerability extended to different domains, including law firms and specific industries, further highlighting the depth of the security lapse.
OpenAI promptly addressed the vulnerability by patching it on August 30. However, subsequent tests by the researchers and independent testing by Engadget replicated some of the original findings, indicating persistent security risks.
This incident underscores the challenges of securing AI models against unintended data disclosure. As AI technologies continue to advance, it serves as a reminder of the crucial need for rigorous testing and ongoing efforts to protect user privacy and data integrity.
In conclusion, this latest revelation emphasizes the importance of addressing vulnerabilities in AI models and the potential risks associated with unintended data disclosure. Through continuous testing and a proactive approach to security, the industry can strive to safeguard user information as AI technologies evolve.
