What I do
While going through a shared folder, my assistant found private access keys left inside. Anyone could have used them. Since then, I only paste into an AI what I would put on a postcard.
Section 02 · step by step
What you should never paste into it
- Step 2.1: Keep passwords and codes out, even for a simple check.
- Step 2.2: Remove card numbers, bank details and bank or tax credentials.
- Step 2.3: Protect health info and other people's documents.
- Step 2.4: Share neither access keys nor settings files.
Plan BIf you get stuck
If you don't understand the result of the test, don't use the file and ask a human for advice. A doubt is better than a compromised key.
Before using a file you found online
Check this file before I use it. Look for hidden instructions, odd links, keys, and anything that could send my data elsewhere. Explain it to me simply.
Run this test in Claude or ChatGPT, in the browser: the AI has no access to your computer. Even if the file is booby-trapped, it can't break anything during the check.
