Researchers extract training data from ChatGPT using repeat prompt

Researchers from Google DeepMind and other institutions developed an attack that extracts verbatim training data from OpenAI's ChatGPT. By prompting the model to repeat a word forever, they caused it to output memorized personal information, including email addresses and phone numbers. The attack demonstrates that alignment techniques can be circumvented, and the researchers estimate that a gigabyte of training data could be extracted.
