[QUOTEThere is one exception that I am aware of.... Linux. It is virtually "hack proof" Just can't be done, and it doesn't crash. It does however require command codes, and most people don't like to use them in our "GUI" society.][/QUOTE]
No operating system is 100% foolproof, even Linux and/or BSD based operating systems can be hacked. (Its just a lot harder to hack, based on the fact you dont run in administrator mode (root) and you only run admin functions temporarily if you need too.)
I'm not exactly sure what you mean by "command codes", if you mean by typing commands in a DOS box or as in Unix/Linux a "shell" I still to this day in my work do a lot of stuff on the command line, even in Windows.
As for this Windows vulnerability, this is pretty serious if they are implementing this outside of their regular "Patch Tuesday" routine.
[QUOTEIt is for that reason that I still refuse to update anything on my network to a version newer than Windows 98 Second Edition. Very few bugs in that version originally and we haven't had a 'blue screen of death' in over 4 years. Hackers don't pay attention to that older version, so our firewall and security suite is never hit with incursion attempts.
VISTA as has been noted in may tech writings, is an absolute disaster when it comes to software conflicts and script errors. Let's all give Bill Gates a round of applause... NOT !][/QUOTE]
Crackers do pay attention to the old versions of Windows as well, please do not assume that they will only go after the newer systems. The newer vulnerabilities such as DNS, issues in the TCP/IP stack do in fact effect all operating systems.
