Security researcher Sammy Hajhamid (Pepsipu) disclosed a software-only, 'tethered' exploit chain for the Switch 2 that achieves userland access via bugs in SmileBasic 4 and the console's FileSystem services module. The hack requires a networked macOS or Linux PC and enables homebrew, game modding, reverse engineering, save backups, and peripheral access, demonstrated with modded characters in Mario Kart World.
A modder known as pepsipu (Sammy Hajhamid) created a software-only, tethered jailbreak for the Nintendo Switch 2, dubbed 'ns2jb,' with help from OpenAI's Codex tool. The exploit relies on the game SmileBASIC 4 and must be re-run each time the console restarts; a demo shows a modified Mario Kart World with added characters like Cinnamoroll, Peter Griffin and Steve from Minecraft.
A developer has published ns2jb, a tethered, software-only jailbreak for the Nintendo Switch 2 running the latest 23.0.1 firmware, via a public repository. The exploit reportedly allows arbitrary native code execution as a system module, enabling homebrew apps, save file backups, reverse engineering of games, and hardware access via MMIO. The developer used AI coding assistant Codex to help build the exploit and to mod Mario Kart World as a demonstration.
