Not good news for Nintendo but maybe good for Homebrew on the Nintendo Switch in the future, heres the news:

Scene Warez Group BigBlueBox is again 'leaking' keys for Nintendo Switch, previously in their 50th Warez Release, they listed in their .NFO file the NCA Extraction Key, and now in their 60th Warez Release for the Dragon Quest Heroes games, the Master Key for firmwares from launch up to v2.3.0, with hints at some point they may release future Master Keys for more recent firmwares like 4.1, so good news for pirates!
