Site reputation – that’s what hackers want to steal from you for their own personal gain. Don’t think that you need to just be using WordPress to become a victim. I’ve seen regular HTML website fall prey to hack attacks too.
It typically all starts with your user name and password being stolen. Hackers create a phishing page that looks legit that they hope you will click and then enter in your user name and password into. The best defense is to never click links in an email and if you do click a link, never share login information no matter how valid a site or form looks.
Instead, go to your login address using your browser and access your account without clicking a link. You will typically find that there is not a problem with your account or access. But the email you had received had some dire notice that you were going to lose access or your account would be closed. Be suspicious of everything.
Troy Hunt has it right in his article on how and why hackers want to get into your site and steal your credentials. His article is worth the read to allow you to make sure to stay safe. You will be amazed at the extent hackers will use, to mask their presence in an effort to steal your credentials and then your website reputation.
