Nintendo Switch, the seventh major home video console from Nintendo was launched on March 3rd, 2017. Just a few days after the release, a hacker called qwertyoruiop
claimed he was able to hack the console by posting an image showing his "completed work". The image shows the Switch screen with qwertyoruiop's name and the word "Done." on it.
The hack was done via the console's browser, which was hidden from users. It seemed that the screenshot revealed by the hacker indicated a Webkit exploit running on the Switch console. Known for Jailbreaks of multiple iOS versions and for the PlayStation 4 1.76 version hack, qwertyoruiop accomplished this hack with a slightly tweak of an existing jailbreakMe iOS Webkit exploit and by removing iOS specific code from it.
For now, nothing regarding how to hack the console is released to the internet, and there's no word from Nintendo as well.
