I scanned 5000 random Jupyter Notebooks from GitHub. Here’s the "Graveyard" of secrets I found.

Amid the AI gold rush, Jupyter notebooks have become a major security blind spot. A scan of 5,000 public .ipynb files uncovered AWS access keys, OpenAI and Hugging Face tokens, prompt injection payloads, and unsafe pickle deserialization risks. Traditional scanners miss notebook outputs, leaving credentials exposed. The real issue isn’t revoking leaked keys—it’s fixing broken developer hygiene before secrets reach production.
