They can't do a major linux virus attack because it probably wouldn't spread due to the fact that linux makes up a small percentage of the users. A virus isn't impossible in any OS, Malacious code is possible in ANY os.
You ignored the point about automated attacks on Windows
servers and not on Linux
servers even though in the server business Linux
is a major player. So why is it that Linux servers are virtually ignored when it comes to attacks and Windows servers are not?
The Russian anti virus firm Kaspersky has been claiming for
years that Linux is popular enough and the wave of viruses equal to what Windows faces is just about to begin. It is 5 years since they proclaimed those attacks were about to arrive any day and we are still waiting. We are waiting because
it is harder and Linux is patched quicker making any breaches a much more temporary thing.
Linux servers have been attacked - successfully. I don't claim they have perfect security - just
better security. If I recall correctly the Debian servers were breached once. The difference is between a hacker directly attacking the Linux server and
automated tools autonomously attacking ranges of Windows servers.
So why is it that the forecasts by pro Microsoft people that Firefox (as mentioned earlier) would be just as badly compromised as IE once it reached a 10% market share have not been lived up to even though Firefox exceeded that 10% some time ago? Could it be that Firefox by virtue of NOT being integrated into the core of the OS does not have the same potential for a determined hacker to take over the system? Could it be that without the ActiveX security mess Firefox is less vulnerable? Could it be that Firefox is patched promptly with no regard to marketing schedules?
Microsoft needs to go back to the non integrated model of the OE on top of the OS running programs. That way you need to breach multiple levels to get to root (admin) access. Also killing off ActiveX would go a long way to help. Not running code clicked on without explicit permission from the user, none of this "You opened the E-Mail" so the attached code runs even though it was "misidentified" as an image.
Beware the
monoculture it is dangerous.
