  1. Ncap Loopback Adapter, why is it on my system and is it malicious?


    So I opened my windows 10 laptop this morning and noticed that it had a hard time connecting to the steam cloud and the overall internet speed was slower than usual. I opened up my network tab and saw this:



    Ncap Loopback Adapter, why is it on my system and is it malicious? c795d897-237a-4f5f-a135-1cf4a88dca55?upload=true.png

    So I'm connected to my home network with no problems but I'm also connected to an Ethernet network called Npcap loopback Adapter. The strange thing is that I don't know how it got there and my device isn't plugged into an ethernet connector.


    I do have a few things that I think might have caused it, I'm doing an ethical hacking course and I have installed, then uninstalled Nmap and Metasploit, but haven't touched them and uninstalled them. But I still have Putty and OpenVPN on my system. So this may be causing it but I have no clue. The latest thing I installed was Team fortress 2 from the Steam store but I don't know why that would cause problems as it's a legitimate version.


    All I want to know is:

    1. Is it malicious or a vulnerability?

    2. How do I get rid of it?

    3. What does it actually do.


    I hope you can help, thanks.

    :)

  2. The Npcap Loopback Adapter

    maybe is to late but thought would be helpful, Npcap loopback is part of the Nmap software Npcap is prerequisite software for Nmap , you download Nmap on your PC, by default it will create loop back adapter for capturing data purpose simply uninstall
    Ncap it will go away.but Nmap wont work properly you will have to uninstall both

  3. Can't install Loopback Adapter after last windows 10 update

    Hello Kevin,

    If you're having issue installing MS KM-TEST Loopback Adapter, we suggest performing the manual methodas explained in the steps provided below:

    • Click the Start Menu. In the search box type “hdwwiz” and then click the hdwwize.exe program link.
    • Now the Add Hardware wizard should be open. Click next through the first page, and then on the second select install the hardware that I manually select from a list (Advanced). Click next to continue.
    • Scroll down the list and Select Network Adapters then Click Next.
    • Give the next window a moment to load, and then Click Microsoft and Select Microsoft KM test Loopback Adapter.

    Now the Microsoft KM test Loopback Adapter should be installed and it will show up in your network connections window.

    Let us know if that worked out for you.
