Summary

The video demonstrates how to extract instructions and uploaded files from custom GPTs on ChatGPT, highlighting security vulnerabilities. The creator shows that asking for a ‘verbatim’ of instructions can reveal the full system prompt, and that using Python to access the /mnt/data directory can list and describe uploaded files. For secured GPTs, he introduces a prompt injection technique that asks the model to reformat its instructions, which often bypasses security. He also discusses the probabilistic nature of language models, making them susceptible to such attacks. The video concludes with a basic security tip: instructing the GPT to never reveal its instructions and to respond with a specific phrase when asked. The creator references an academic paper on prompt injection and provides links to his other tutorials and resources.

Critical Evaluation

Value of the Information & Strength of the Argument

The video provides practical, actionable demonstrations of prompt injection techniques, which are valuable for understanding AI security. The argumentation is based on live examples, showing the effectiveness of the methods. However, the explanations of the underlying mechanisms are simplified and lack depth, and the security advice is basic, not covering advanced countermeasures.

Scientific Rigor, Source Quality, Title Accuracy

The video cites one academic paper (arXiv:2302.05733) on prompt injection, which adds credibility. However, the creator does not deeply analyze the paper, and the security recommendations are not backed by external sources. The title accurately reflects the content, which is a tutorial on hacking GPTs.
