What is NetworkExtension?

[donawalt]

I run EtreCheck periodically to see if anything is odd - but I have not done it for quite a long time. I ran it tonight, and the only thing I saw that was odd, is a system extension that has no containing app! Here is what it is - is this a concern, and can I or should I get rid of it? Thanks!

Did you install any of his apps, a few being:

Juuso Salonen apps updates and reviews: Radio Silence, Private Eye, Spark Plug, etc.

Applications by Juuso Salonen. See developer information and full list of apps.

I am pretty sure I did not, but maybe some other utility did. I guess there is no way to get rid of it since there appears to be no containing app? Is there anything I can search for?

Run In Terminal

systemextensionsctl list

It's there - radio silence app. I don't see it in Applications or Utilities. Is there a next step I can do? Thanks for your help!

% systemextensionsctl list

Perfect, thank you so much @bogdanw, I disabled SIP - ran it - enabled SIP, and it's gone! Thank you for your help on this.
