Team Fail0verflow have uploaded a video showcasing a Nintendo Switch running an exploit as the console starts (video below).
This announce happens right after Team Xecuter stated they would release a hacking “solution” for all models of Nintendo Switch in Spring this year. I don’t believe in coincidences here and I personally read this as a message from Fail0verflow to Team Xecuter, that whatever commercial scheme they have in mind could be trumped by a free hack. The announces from these two teams happen as a homebrew launcher has been scheduled to be released for firmware 3.0.0 in a few weeks.
With that being said, Fail0verflow haven’t released fully weaponized hacks in a long time, in particular on the latest firmware of current generation consoles, so it is not clear if they intend to release anything at this point.
The “Demo” runnning at boot on the console in their video states:
Fail0verflow presents shofEL2, a coldboot exploit for NV Tegra. Greetz from this dinky ARMv4T Core to all Switch hax0rz! Interesting Times ahead…
It is also not clear if this is running on the Switch latest firmware (Team Xecuter have stated their solution is “Future proof”, a claim that many hackers have debunked as an unrealistic sales pitch – Nintendo could always release a hardware revision), or if there are limitations involved. But given the video says it is an exploit on the CPU itself, this could be actually working on all firmwares.
