I don't agree. There is a big difference between "attachments". I'm
sure end users don't open executable files and it should be nothing
wrong with opening JPG/PDF/DOC/XLS/etc (with the exception of zero day
vulnerabilities) files. However, most of viruses are using well knows
vulnerabilities in desktop software such as Acrobat/Office. All these
viruses are targeting unpached software in order to execute the code
on the victim's computer. The same goes to servers. Attackers always
look for the weak chain in your system: well known vulnerabilities and
existing exploits would be the easiest way to your network.
