Patched Nintendo Switch: Youtube

However, long before that official release, hackers had already discovered the "Pegaswitch" exploit. This was a user-land exploit that used the web browser (which was hidden but accessible via DNS tricks) to run homebrew code.

When the official YouTube app finally launched, security researchers immediately began reverse-engineering it. Why? Because the YouTube app contained a —a component that renders web pages. And WebViews have historically been the Achilles' heel of locked-down systems. The Core Vulnerability (CVE-2019-####) In early 2019, a significant vulnerability was discovered.

Community forums erupted. "Don't update YouTube!" was the rallying cry. But because the Switch checks for app signatures online, it became nearly impossible to launch the old, vulnerable version without permanently disconnecting your console from the internet—defeating the purpose of YouTube. With the release of Firmware 16.0.0, Nintendo implemented a system-wide ban on specific title IDs. The older version of the YouTube app (Title ID 0100ebf00c9e2000) was blacklisted from launching unless updated. Furthermore, Nintendo patched the kernel to prevent the specific syscalls the YouTube exploit used. However, long before that official release, hackers had
