I am having a problem with this popping up continuously. I have searched the internet for an answer but can't seem to find why I am getting it. It shows that my MAC computer on my network and sitting right beside the computer I am typing this on (Windows 10 PC) is the computer trying to access this computer. It shows the threat as an SMB:BruteForce and the URL as the IP address of the MAC computer. It has popped up while typing this. I am attaching a photo of the popup.
What I'm not sure of and trying to be cautious about is, is this just within my network or is this coming from outside of my network? I have been doing everything to shore up security just in case. Please give me a hand in figuring this out.
