Hacking Guru Meditation Error

[E1ite007]

Howdy fellow tempers,

I was looking Facebook, when I saw an error I've never seen in my life neither on a Wii or a Wii U. And just out of curiosity, I would like to know what kind of damage, software or hardware related, could 'cause this.
Anyway, it's this one:

The only time I saw an error like this was for the NDS... and I think the 3DS. But I've never seen a Guru Mediation Error on Wii U.
What could be the 'cause for a problem like this?

Not my problem actually, just asking for kicks. I saw this on Facebook, and I don't know any setup or context.
Just searching for any kind of reasons this could happen, of any kind of nature.
