Well, this is an easy question. Because it is extremely popular, and WordPress now powers over 28.9% of the web, currently running on over 75,000,000 websites worldwide, and it’s now by far one of the most popular content management system software out there. It is used by bloggers, small businesses and even large brands like The New Yorker, TechCrunch, Sony Music, MTV News, Time Inc. and many more.

2. Mail Spam

Unfortunately, we all know what spam emails are, and everyone gets a few of these daily. Also, the overall number of spam emails sent decreased in the past few years, this is still a big problem, according to the Kaspersky Lab report published for Q2 2016 over 57.25% of the emails they analyzed were spam.

So you might ask yourself from where are these emails being sent and why isn’t anyone stopping them? Well, the short answer is from your compromised website or account.

The spammers can send out thousands of emails in just a few minutes, which will come from your server or website. In these days spam equals money, there are still people who don’t delete the spam message as soon as they receive them, and do follow up on the emails received, supporting and encouraging this type of business.

3. Serve viruses to your visitors

The attackers can modify your website to serve viruses to your visitors, so the next time anyone checks out your websites they could be infected if they don’t have a security app installed on their computer of it the OS is not up to date.

They could, for example, serve a ransomware virus which will encrypt all your visitor’s files, and decrypt them only after payment.  According to Symantec, they blocked over 320,000 ransomware infections, in the first six months of this year, which is a significant increase over the last year.

Attackers might insert malicious code that redirects your website visitors to other phishing or malware websites, and this can have a devastating effect on your website’s reputations as Google might start removing your pages from their search results if you don’t act quickly.
