Tavis Ormandy has ported Windows Defender DLLs to Linux with the aid of a new tool he released today on GitHub. The new tool is named loadlibrary, and it’s created for the sole purpose of helping security researchers, not necessarily the Linux user community. The default loadlibrary package includes a demo in which the researcher ported Windows Defender on Linux. The tool is attractive to app developers, who can use it to load DLL data into Linux apps without having to port the entire Windows app along the way.
