: Users who downloaded it found that the .rar file was encrypted with a complex password that no standard "brute-force" software could crack.

: Those who claimed to have opened it never posted the password. Instead, they posted cryptic warnings or "last messages." They described the contents as a series of non-Euclidean geometric images, audio files that induced physical nausea, and text documents written in an unknown language that appeared to change every time the file was opened.
