How to Detect Unauthorized Connections created by Windows PC – Guide

Every day, people like you spend more and more time online. Through the connections your computer forms with other sources, you get the information you want from the Internet. Most of the time, these connections are entirely harmless, but malevolent behavior could be taking place below the surface. You may not be aware that your computer is transferring confidential information.

There are a few simple techniques to examine all the connections your computer is making if you’re afraid there’s malware or a security issue. Viewing a list of open ports and processes can reveal illicit connections or data transmissions. There are several tools that can show you connection information. This post will show you how to use two web tools and a Windows procedure to do this.

How to Detect unauthorized connections that a Windows computer is creating

Using PowerShell

To access your connections using PowerShell, first press Win + x. The Power User menu will open. This menu provides shortcuts to various tools in Windows.

Then select the option for PowerShell (admin). You need administrator privileges to run this tool.

Type this command:

netstat -abf 5 > activity.txt

and press Enter. At this point, your computer will start recording connections being made and save them to a text file.

Now let the program run for a few minutes. You can keep working on something else if you want.

Stop recording data by pressing Ctrl + c.

Type “activity.txt” and press Enter to view the information the program recorded.

Finally, open the .txt file in Notepad.

This Notepad document is stored in the System32 folder as shown below if you need to refer to it later.

If you find something on the list that you don’t recognize, look it up online. If it’s something that could be dangerous to your computer or privacy, search again to find out. how to remove it.

Using TCPView

Microsoft’s TCPView is an online tool for viewing connections. You can download it for free and it is also part of the SysInternals toolkit. When running this program, you will be viewing the list of connections in real time. Since it’s real-time, you can terminate processes, close connections, and search up more information directly from the tool as it runs.

To use TCPView:

Directly from there, the tool will start displaying all the current connections your computer is using. If you see something you are not sure about, right-click on the process and click on “Whois…” to get more information about it.

As the program is running, specific lines of data are highlighted with red, yellow, or green lines. These colored lines call attention to any changes in the processes. A green highlight shows a device connection that has just been opened, and when it closes it will turn red. Yellow highlights indicate that a change has occurred in this connection.

This program works quickly, and the display jumps to different parts of the list quite often, sometimes making it difficult to click on a specific line.

If you plan on using this frequently, you might want to drag the application’s .exe file to your desktop or carefully note where you saved it. It does not create an icon or add it to your program list.

CurrPorts

CurrPorts is another online tool available for download from Nirsoft. It is very similar to TCPView but offers some more focused information. It also indicates changes in connections, but has the addition feature to highlight any suspicious activity with a pink highlight.

To get this tool, please download it. It’s near the bottom of the page, so keep scrolling. Make sure you download the correct version if you need the program for a 64-bit version of Windows.

The installation process is identical to that of TCPView.

If you think something strange is going on with your computer, these programs and tools will help you find a solution to the problem.
