Oh I disagree with that.
Wordpress is targeted by hackers. The hackers work very hard night and day to crack the wordpress code.
Usually the cracks aren't even discovered for months.
Yes wordpress is good about updating their security... when they know about a crack.
But like I said they often don't find a crack for months and months after it has been successful.
Most large scale bot-networks are comprised primarily of sites running wordpress.
