What they did
1kleos1 bought a used laptop and its fan kept spinning at night with the lid closed. He asked Claude Code what was running that he never installed, and says it found an app that had been turning on the camera at 3 AM.
Result (as claimed)
A hidden camera-using app found on a second-hand laptop.
Tools they used
Cost: Pricing depends on the tools you pick; check each official pricing page.
Set it up
Define the job
Say exactly what you want done and what the agent may and may not do on your behalf.
Share only what is needed
Give Claude Code the minimum files or access required. Avoid sharing passwords in chat when a safer login flow exists.
Review the plan
Ask the agent to show its plan or draft before it acts, and approve each step that has real consequences.
Check the result
Confirm the outcome yourself (order placed, request sent, document understood) and keep a record.
Copy the full setup prompt
Paste into your agent and it will walk you through the setup, asking before anything that sends, posts or spends.
