If you are reading this page because our port analysis has revealed that you have open ports lying between 1024 and 1030, it would certainly be in your best interests to configure your personal firewall to block incoming connection requests (TCP SYN packets) to those low-numbered ports.

The culprit my best guess is the above noted process.
May 16, 2017 · To determine this we matched the raw packets captured by Heisenberg on port 445 against sample packets known to exploit MS17-010. Figure 5 shows the number of unique IP addresses scanning for port 445, grouped by hour between 2017-05-10 and 2017-05-16. The black line shows that at the same time that the number of incoming connections increases
Mar 12, 2020 · For users who are unable to patch immediately, Microsoft’s guidance is to disable SMBv3 compression and block TCP port 445 on firewalls and client computers as a workaround.
