Question

If a browser is sending out requests ....

If a browser is sending out requests / information or trying to connect to a specific IP..or port.

How or where do I go within Sierra to find where the request is generated from so that I can see what is causing it to happen. Is it a plist. or an exe. or com.apple file. I am looking for some direction as to finding who is trying to hack into my Mac. Browsers in question are Safari and Vivaldi. Someone recently sent either a script or some other way and was able to wipe put all of my court files for an upcoming case from 3 different computers on the same network.

I am now using Murus Firewall and Vallum which seems to show what is happening but not who....

Can anyone help with this please.

Thank you,

iMac, macOS Sierra (10.12)

You can go to system preferences > security and privacy > open the pad lock by entering admin name and password ( if you are having admin account ) > firewall > firewall options > check the box of Block all incoming connections and stealth mode and do the settings as per the screen shot .

You can enable file vault so that data is secured : macOS Sierra: Encrypt the contents of your Mac with FileVault

Also , change the password for all of your accounts , if possible do a factory default reset for your internet service provider modem and Air port express ( in case you are using ) .

Also , install Malware Bytes Anti - Malware for Mac that is good software to clean malware .

I am not using any tools, because they normally do more than you expect, but in this particular situation you could use LittleSnitch to find out who/what is sending out, block that one and unistall if necessary.

Malwarebytes will probably clean it out too.

After that you can uninstall Little Snitch (or "immobilise").
