After March 27th, owners of the systems won't be able to make purchases on the digital storefronts, but they'll still be able to download titles they previously bought.

The issue emerged only a few weeks before Nintendo shuts down the Wii U and 3DS eShops. Those who are still playing the games on the discontinued system might be disappointed that the online features are currently unavailable, but it seems Nintendo was left with little choice but to take them offline for now. The original Splatoon sold almost 5 million. With nearly 8.5 million copies sold, Mario Kart 8 was the biggest-selling game on the Wii U.

PabloMK7 wrote on GitHub that 'it would be theoretically possible' to steal an account or credit card information and to record a victim using the 3DS' mic and cameras. It's used to inject custom firmware onto the targeted console. Nintendo has seemingly patched all of those titles to protect them against the exploit.Ī video posted by YouTuber PabloMK7 in December shows ENLBufferPwn in action on Mario Kart 7. Several Switch games apparently were too, including Mario Kart 8 Deluxe, Animal Crossing: New Horizons, Nintendo Switch Sports and Splatoon 2 and 3. Mario Kart 7 on the 3DS was previously vulnerable to that exploit.

Dataminer OatmealDome suggested the issue is “almost certainly” due to ENLBufferPwn. We apologize for any inconvenience caused.'Īs VGC notes, the vulnerability could be related to an exploit that allows an attacker to take control of a victim's system simply by way of being matched with them in an online multiplayer game. 'We do not yet have information on when network services can be restored. 'This network service is currently unavailable due to urgent maintenance required to fix a vulnerability related to online play,' reads a message posted to Nintendo's website at 11:30PM ET on Thursday. Nintendo has taken Wii U titles Mario Kart 8 and Splatoon offline indefinitely while it attempts to resolve security issues.
