Im using a non standard port in the 40,000 range. Changing the port won't necessarily stop the traffic. A lot of these bot nets will portscan an entire ip of anything that has port 80 open to find non standard ports.
Back in August of 2023, I would gets *hundreds* of SSH login attempts per minute. Looking at my logs, the numbers have dropping precipitously ever since.
As of this month, I only received 17 attempts. All from the same IP range.
