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)

I think it could be guys from some japanese forum, though i don't have a clue who is doing that and i don't recall visiting any this week. It someone probably from /prog/ or connected to /prog/ but i'm not sure anymore.
