So, one Linux myth bites the dust
Not the one where Linux didn't have any viruses. That myth has sunk a while ago already. But the myth that Linux, being a niche product, did not attract hacker attention.
With hindsight, that myth couldn't hold water as soon as half of the Internet started running on Linux. Linux on the desktop is still a pipe dream, but Linux in the server rooms is very real, and I'll wager there are more Linux server than there are Windows servers at this point in time.
And those hackers were attracted to the servers, and their sweet, sweet data.
I'm sure that admins that are on the ball already have proper firewalls and anti-virus tools in place, plus maybe monitoring and intrusion detection for the best of them, Linux or no. For the rest of you, this is your wake-up call. Linux _is_ vulnerable.
So patch and fortify your defenses.
