Hello, Today i noticed someone using a private-IP was browsing my website? I've blocked it from the router but still doing it any idea?
Private IP? Could be browsing from a Proxy. Check your logs, see what they did, how long they spent on the site, and then afterwards, go through your sites files and look for anything suspicious. It's also a good idea to back up your site/databases now to save the hassle later. Auto generate backups if you can, I have a cPanel CRON that does this if you need it.
