I found this showing up in my logs recently.

     [21/Jun/2021:19:07:19 +0000] "GET / HTTP/1.1" 301 169 "-" "Expanse, a Palo Alto Networks company, searches across
 the global IPv4 space multiple times per day to identify customers' presences on the Internet. If you would like to be excluded from our scans, please send IP addresses/domains to: scaninfo@paloaltonetworks.com"

I remember thinking that ads in server logs was a new one to me.

Let me explain, I am not running any services on standard ports. You'd have to do a port scan and find one of the ports running a web service. But they're HTTPs (with unsigned personal certificate keys, mind you) and are password protected.

I still get so. many. random people entering passwords and trying to break in. They don't look like a wordlist or automated bots, they're literally people guessing.

Just because you see a username and password screen after you nmap this public IP, doesn't give you the right to start trying to hack it.
