Udi, There are many ways to go about this, beleive it or not. The question really becomes...who am I hiding this file from? I won't go into a lot of detail now...I don't want to steal my own thunder, ie, my BlackHat presentation in Feb...but Jose pointed out NTFS alternate data streams. You can hide data or even executables in ADS and run them directly from the ADS itself. But again, the question is...who are you hiding the data from? Hiding from a user or a (perhaps less than knowledgeable) admin is pretty easy, w/o using the hidden DOS attribute. How about hiding it from a forensics analyst? Alternate data streams won't work for this, and will only highlight your intentions. But there are ways to go about this...so stay tuned.
I was wondering if there's a way to hide a file under windows 2000 server, so that it will not be seen when using "show hidden file", "show all files" and so on. I want to hide a file but I want to be able to run the file only when I know exactly where it is and what is the file name. Do you guys have any Idea ?
