Failed Logon Attempts on my PC

Question

I have several (over 20,000) login attempts coming from a suspicious IP. I think I'm getting bruteforced. I don't understand how since I use a NordVPN and as far as I know, they don't have a way to get inside my network. I do have remote desktop enabled, though. Can someone take a look and help me out, and figure out what I'm looking at?

Answer 1

Disable Remote Desktop when not required and when required enable that.

If you must keep Remote Desktop on, ensure you have a very strong password set for it. A long password with a mix of upper and lowercase letters, numbers, and symbols is ideal.

Wherever possible, enable two-factor authentication for your accounts.

Run a scan with your antivirus software to rule out any malware that might be facilitating the attack. Update the system.
