Has anyone tried running nmap or any other port scanner on their WiiU yet? Or better yet a Nessus/Nexpose scan? If so can someone post their results here for the rest of us that can't afford a WiiU yet?
Also while anyone is at it, maybe try a packet capture(wireshark or tcpdump) from when the system boots, and maybe try updating and then share the pcap file with us. I'm not sure how anyone came up with letterbomb, but around the same time I was trying to find an exploit that would work against the version of Opera(buffer overflow) on the original way but I gave up after letterbomb was released. Knowing the way the WiiU talks to Nintendo and vice versa might open alot of doors though.
