I have only Gmail and Brave community open when I run this command. These domains that Brave says it has open network connections to do not match the tabs I currently have open. This is a man-in-the-middle attack on the Brave Browser. I have been a whistleblower and I believe I am being harassed in retaliation with military grade hacking tools. You can verify this if you are on a Mac. If you have gmail and Brave community open this command will show a different output for you because your Brave Browser has not been compromised as mine has. This same command works in Linux also.
sh-3.2# lsof -i | grep ESTABLISHED | grep Brave | head -n 4
