Someone tried to hack my router

I just checked access and it shows someone externally connecting to a router i use,
someone using a japanese nick and apple computer hardware. I can assume only one from /prog/(or /jp/?) is leet enough to do it.
If you have a problem with me just ask here. Wrecking my router is not going to help(at most i'll just reset the hardware)

someone once tried to do a brute force login into my ssh daemon, by trying many different usernames and passwords randomly. I suppose if I never noticed, he/she may have succeeded after a decade or so. I made a frequency table for the usernames they tried.
