From the file’s version info and the copies recorded by xCyclopedia (MIT). A copy in another folder, signed by someone else or with another hash is not necessarily malicious, but it is worth a closer look. In Ceplin, "<sha256>".whatis() says which known copy a hash is.

What detects it

Sigma names wincredui.dll in 1 rule, for every kind of event; none is a process creation rule CmdID evaluates, so none is listed.
