an hour ago I restartet my computer because NIS was not available. after that I tried to start NCC in browser and had a new wallet in my nem ncc directory böser dämon is the wallet called: B%C3%B6ser+D%C3%A4mon.wlt
and NIS is not available since then. Maybe I got hacked because how could be a wallet in my ncc directory, which is not my wallet?
Hi himmelsfaller! Sites like nodeexplorer.com expose your IP address. With this information anyone could try opening NCC over the web via
http://xx.xx.xx.xx:8989/ncc/web/index.html.
Chances are someone accessed your NCC and created that new wallet. When running a public node, it's best not to have NCC running (running NIS with unlocked account is all you need to keep harvesting) or change its port to something unique only you know. I could imagine that NIS is not available because the same person specified a remote server (probably non-available one), which is why your NIS doesn't boot/refuses booting.
In NCC, go to Settings and see what is specified. Change it back to your previous settings. If you have harvesting activated, you can go ahead and close NCC. Then simply keep NIS running.
It is actually kind of a flaw that NIS can easily be made unavailable simply via NCC's front page at this point. I wanted to point this out earlier but you reminded me. Hope that helps.
