Conclusion

WordPress sites are being hacked and infected every day. Some statistics say that about 30,000 websites are infected with some type of malware daily. Every public website is a resource available on the internet and therefore it’s a target. It’s important to understand that as soon as your website is available to the public, it immediately becomes a target.
