WordPress powers nearly 73M (million!) websites around the World, making it the most popular CMS in existence right now. About 15% of the top one million sites on the web use WordPress, including business heavyweights like Honda, the New York Times, CNN, NASA, TechCrunch and others.
Those are some impressive stats for something that started off as a humble little blogging platform but has grown to become so much more. WordPress’ extensibility (the ability to add plug-ins for almost any functionality you can think of) and ease of setup and use have certainly contributed to its explosion in popularity. But unfortunately that ease of use and popularity are also what make WordPress sites an attractive target for hackers.
