The breach, named 'TeraLeak' after the 2020 'GigaLeak,' included insider information on Nintendo Switch 2 codenames, source codes for games like Pokémon HeartGold, data on future Pokémon titles, and an unannounced game. Despite confirming the breach and strengthening security, Game Freak did not verify the leaked information's accuracy or reveal if Pokémon or Nintendo-related data was exposed
