This is infuriating that I continue to get this repeats of nine and more possible hack attempts from the same certain IP addresses blocked by Malwarebytes, which I get popups every time it happens. This is a snapshot from my logs after one has happened, and I also save text file logs of it.
From what I can tell, they appeared to be originating from Linode almost every time and when I tried to file complaints with them, they keep claiming it is a security researcher or something and end up doing nothing about it. I’m currently wondering what to do about this as I have a folder of so many save logs of it on my computer.

It’s normal to get scans/attempts on any public IP.
That said, malwarebytes is usually run on personal computers, do you have ports forwarded to your PC from the internet?
No, I don’t have any ports forwarded to my PC from the internet as far as I’m aware.
If they are making it past your firewall and hitting your computer then the firewall is open and it shouldn’t be. Or that’s an outbound connection triggering the alert.
Just clarification here, a NAT is NOT a firewall. It will drop packets originating from outside the network if the ports aren’t forwarded to an IP simply because the NAT has no idea which device on the network to send the packets to. A forwarded port is you telling the NAT to assume packets coming into a specific port should be forwarded to a specific device. It is acting as a security measure simply by coincidence but not by design. Unlike a firewall it will not inspect any packet payload or attempt to make a security decision on outbound packets. It only routes based on the packet headers.
A firewall on the other hand actively will reject or drop packets because it is an Intrusion Prevention System (IPS). This is why if your router has a built-in firewall, your NAT will still drop the packets – because it isn’t a firewall nor is it what is being referred to if you disable it.
