How to hide a file ?

["Kurt Seifried" <bugtraq () seifried org>]

Just a note: Tripwire will pick it up, i.e. if you add an ADS to a file
tripwire will flag it, and if a file has an ADS that is modified or removed
tripwire will also flag it (with MD5sum/etc just like a normal file). The
other good news is if you add an ADS stream to a directory such as WINNT or
system32 it will detect it. Of course any files or dirs not listed in your
policy will escape tripwire, but then that's no big surprise. So my advice:
use ADS on files specifically excluded by tripwire if you want to hide
things.
