Shadow AI: When Staff Paste Secrets Into a Chatbot
Shadow AI data leakage is rarely caused by a hacker. It comes from a helpful employee pasting the wrong thing into the wrong chatbot.

Explain Like I'm Not a Hacker
Reading your company's private plans aloud on a crowded train because you wanted quick advice: that's shadow AI in miniature.
The 30-second explanation
Someone wants to summarise a contract or debug some code and pastes it into a public chatbot. The data has now left the company, without anyone meaning any harm at all.
How it works
- 1
1. Need
Someone wants help with a task.
- 2
2. Paste
Data is entered into an unapproved tool.
- 3
3. Leave
The content is now outside company control.
- 4
4. Consequence
Exposure, compliance or contractual issues.
People adopt AI tools because they solve a real problem quickly. If the approved option is missing or awkward, they reach for whatever works instead. What actually creates the risk is what gets submitted: customer data, source code, credentials, incident details, typed into a chat box without a second thought. Once that content sits inside an external service, the organisation often has little real control over how it's stored or used afterwards. The fix is a mix of approved tools people actually want to use, clear rules on what may be shared, and technical controls for the most sensitive data.
Real-world example
A developer pastes a chunk of code containing an access key into a public chatbot to debug it. The key is now in a system the company does not control and has to be rotated.
How to spot it
Traffic to unapproved AI sites
Frequent use of consumer chatbots from work devices.
Data pasted without review
Files or logs copied into prompts.
No approved alternative
Staff have nothing sanctioned that does the job.
Unclear rules
People unsure what they may share.
What to do
- 1Provide an approved AI tool that is easy to use, so people do not go looking for others.
- 2Publish simple rules: never paste credentials, personal data or confidential incident details.
- 3Use data-loss controls for the most sensitive categories, and rotate any secret that has been exposed.
Stay curious. Stay safer.
