Nintendo has taken Wii U games Mario Kart 8 and Splatoon offline for security reasons
Nintendo has taken two of its most popular Wii U games offline to fix what is says is a security vulnerability.
Both games were taken offline at 8.30pm PT / 11.30pm ET on Thursday (4.30am GMT today) to fix the issue, and Nintendo suggests it may be days before they’re back online.

A recent YouTube video by PabloMK7 shows how the exploit could also be carried out on Mario Kart 7 on the 3DS (which has since been patched to prevent it).
In the video, the hacker’s 3DS is shown connecting to another player’s 3DS via the game’s online multiplayer. The hacker is then able to take control of the other 3DS and forces it to install custom firmware.
PabloMK7 notes that “using the same techniques, it would be theoretically possible to steal account/credit card information or take unauthorised audio/video recordings using the consoles built-in mic/cameras.”
