Those who prey on insecure web servers rely on users who are lax, lazy, or unknowledgeable about keeping their servers hardened and updated. Essentially, the climate of the Internet has degenerated into a situation in which even innocent users that get penetrated are used as attack vectors against other innocent but open servers. The responsibility lies not just with the attackers who promulgate these worms, but also with the administrators who allow their machines to be used like toys.
