That&#x27;s an interesting opinion... what makes you think it&#x27;s the easiest OS to target?  Do you have any data to back up the claim that a modern Windows OS is less secure than it&#x27;s major competitors (OSX and, in some circumstances, Linux)<p>My feeling would be that Microsoft have done a lot in the security line and have also given a lot back to the security community (their SDL documentation which is freely avaiable for example) and that they are one of the better examples of security in the software industry these days
