spoofed a streetpass "AP".
StreetPass is a feature that allow your 3DS to connect with other 3DS using WiFi in standby mode.
StreetPass is a feature that allow your 3DS to connect with other 3DS using WiFi in standby mode.
It can be used to share Mii(s) on Mii Plaza for example. Games' StreetPass data is stored on SD card.

Using Wireshark tool with a WiFi card in monitor mode allow you to see the data used to scan for other 3DS in the range. The below is a broadcast probe request from an 3DS while in standby mode, with SSID "Nintendo_3DS_continuous_scan_000". When in "active" mode, 3DS sends probe requests with arbitrary SSID strings, like "ic[kSvm9s@*cYD>/~IEVj\(fGG;qDo8j". This frame also contains a custom Nintendo tag, it seems to contain unknown console unique data, since the contents of this tag from different 3ds captures don't match.

When in standby mode, ds-mode NTR wifi is used,(this includes SpotPass and StreetPass) but in "active" mode the regular TWL wifimmc bus is used.
When in standby mode, old DS wifi is used,(this includes SpotPass and StreetPass) but in "active" mode the regular DSi wifi bus is used.

A streetpass "AP" was spoofed on a laptop with hostapd by setting the SSID to "Nintendo_3DS_continuous_scan_000", with the extra Nintendo tag from another 3DS' probe request. The SSID and AP can't be easily spoofed with hostapd for streetpass when 3DS is "active", for the random "ic[kSvm9s@*cYD>/~IEVj\(fGG;qDo8j" strings. The 3DS didn't seem to authenticate or associate with the "AP". Streetpass "AP" comms use WPA2 [http://en.wikipedia.org/wiki/CCMP CCMP] encryption. Eventually the 3DS stops communicating with the fake "AP" since the AP doesn't understand the sent data,(especially since it's encrypted) and sends a 802.11 "Action" frame, with category ID 0x7f and Nintendo's vendor ID: 00 1f 32.(However the 3DS keeps communicating with the above process repeatedly)
