Is Linux safe from attack?

VNUnet.com: “There’s been a long-standing belief throughout the Linux community that
hackers and virus writers had better things to do than target them with
malicious attacks – a belief that is beginning to erode.

As Linux increasingly becomes a target for malicious attacks, the question
arises as to how vendors and users should deal with the problem. Is it a
case of developing antivirus defences specifically for Linux or is it the age
old problem of increasing awareness of the threats within the open source
community?”
