# teamviewer\_scanning\_internal

**Explanation**

The teamviewer\_scanning\_internal NDM is designed to detect any unauthorized scans on your internal network looking for the TeamViewer software.

**What to Look For**

To identify teamviewer\_scanning\_internal, you should look for any suspicious scanning activity on your internal network looking for TeamViewer instances. Also, check the TeamViewer logs for any abnormal login attempts or remote connections. If this NDM is triggered, it may indicate a potential security breach or unauthorized access to your internal systems. You should immediately investigate the source of the activity and take appropriate action to remediate the vulnerability.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.fusion.vectra.ai/detection-models/library/reconnaissance/teamviewer_scanning_internal.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
