What Hacker News says

62 sources
Seems like a revive of: https://github.com/desktop-app/lib_webview/commit/77b1712a8f... (2022) where you could open an app by running window.open("C:\Windows\system32\cmd.exe") This is a guess based on the behavior in the video, and on the recent fix on Media Preview feature of "Instant View" attachments: https://github.com/telegramdesktop/tdesktop/commit/eaaa704fa... (3 days ago) so potentially could be just to send an Instant View link pointing to an executable app instead of a website.
