Frosty is a sophisticated rootkit malware developed specifically for Windows operating systems, with an emphasis on its compatibility and effectiveness with Windows 10.
A notable feature of Frosty is its use of Microsoft's Detours library. This strategic choice allows the malware to engage the Windows Native API (NTAPI), the application programming interfaces essential to the operating system's functions. Manipulating NTAPI allows Frosty to bypass conventional security measures and avoid detection by traditional methods.

The Frosty rootkit is in its early development phase, so we are in beta. We welcome feedback on the rootkit so we can improve it.
This is one of my ambitious projects, as much as it is a ring 3 rootkit, it was a project in which I learned more internally about the Windows operating system. So if you find any bugs, please report them in issues so we can reach a final point and fix them.
