Users are urged to download only from the official GitHub page [tomshardware.com]:
With Windows 10 reaching its end of life (EOL) last month, a free third-party tool called Flyoobe (which we have covered here [tomshardware.com]) has been gaining popularity for enabling safe upgrades to Windows 11 on unsupported systems by bypassing the system requirements. Additionally, it includes various options to customize the OS further, such as removing AI features and unwanted apps. However, there is a suspected bogus build [github.com] of this tool downloadable via an official-looking domain, which is causing concern.
The developer of Flyoobe recently issued a warning about a potentially malicious copy of the tool being distributed through a website that is not directly affiliated with the project. According to a notice marked "SECURITY ALERT" on the official Github page, an unofficial mirror is being hosted at https://flyoobe.net/ [flyoobe.net] (do not visit), which may contain malware or a tampered build of Flyoobe. The developer also urges users to download only from the official GitHub releases, emphasizing that the mentioned website has no connection with the developer or the project’s official pages.
WindowsForum has detailed procedures [windowsforum.com] for downloading and verifying the official version.
