sudo - Indicating that it needs to do the command as administrator
nano - One of the many command line text editors (in the example, it just opens it to your hosts file)
whoami - Indicates the login name of the user currently logged in
networksetup - Your network settings
 
Hi,

So what did these commands do?

I did not enter these commands.

Is my Mac hacked?

Thanks.

sudo nano /private/etc/hosts opened your hosts file and then exited. You can't tell if something was written into it by just those lines.

In the lines after that, it set the proxy to the localhost and then turned all the options off, meaning it's not using it. If you need to check (I don't see anything going wrong in the ones you listed though), you can go to System Preferences > Network, click on Wi-Fi, Ethernet, etc, and then Advanced. Then Proxies.

These are the settings those commands refer to:

Yeah, it would be useful to know where you're getting these.

One can also use 'networksetup' to read the current settings. Example:
Code: 
networksetup -getsecurewebproxy 'Ethernet'

The man page for 'networksetup' has a gazillion options. The ones that get state don't have to be run with 'sudo'; the ones that change state do.

Man page for 10.9's command:
https://developer.apple.com/legacy/...n/Reference/ManPages/man8/networksetup.8.html

I'll also note that port 21218 is not an assigned IANA port, so it's unclear what the intent of setting that port is.

Hi,

I found the commands in the Terminal on my iMac.

BTW, why would anyone want to change(or know) my Network settings?

Thanks.

They could be redirecting your browsers to malicious sites. Does anyone else have physical access to your computer? If so, you should ask them. If your computer is not password protected, you should password protect it.

Also, you need to download MalWareBytes and EtreCheck and follow the instructions in my earlier post.
[doublepost=1469996230][/doublepost]Also, you want to know if any changes were made to your Hosts file as that can be used to redirect your growers.

To find out, in Finder pull down the GO menu to Go to Folder and type in

/etc

and hit return.

Scroll through the /etc window and look for a file called "hosts". Right-click on it and choose Open With the Text Edit.

Type Command-A to select all, then Command-C to copy. Then paste the result into a message here.

Hi,

What do you mean "set the proxy to the localhost and then turned all the options off"?

Thanks.

Hi,

What did the "sudo networksetup" commands do to my Mac?

I had problems with my Safari browser. It opens tabs and leads me to other pages when I click on a link. And shows Adobe Flash commercials also. The system also ran very slow.

Are the problems above caused by the commands ran on my iMac? Can some kind of "programs form the Internet" do that?

Thanks.

Ed

ps. The "sudo nano /private/etc/hosts" command is okay. I checked my hosts file and it's not modified.
