How to look with what IP addresses there are attempts of selection of the password ?
How to protect itself from such attacks ?
I have changed parametre in a file loginserver.properties

# How many times you can provide an invalid account/pass before the IP gets banned.
# Default: 10
LoginTryBeforeBan = 5 (Was 10)

imo those are not "hackers", but just dumb ppl who don't know you have auto-registration disabled.
what do you even mean by "selection of the password" if they're choosing the wrong USERNAME?

Account missing for user moiiinsq

Probably someone trying to bruteforce "moiiinsq" password or its just that the idiot forgot it.
