Hello everyone! A week ago I created a private Hamachi network, with a strong enough password. I shared the networks password with two friends I know pretty well. Everything was ok until today, when I saw that another unknown device on this network. I'm not really sure if creating another network with another password could solve this problem. Any ideas? After a bit of searching, all I know is that this person is probably from Romania. Oh and btw I gott a lot of phone calls from unknown people in the last few months.
