Malicious hackers are using sophisticated ransomware to lock you out from your valuable data - if they find a way to get to it. They will demand you pay them money to unlock your data to regain access. To prevent such a malady, you need to take basic security precations when building your site:
• create basic login/logout pages to intercept acces to pages containing your data and block access if faulty credentials are given
• create user registration to allow your readers to enter their poc infomation
• Allow your users to modify their profile info, retrieve forgotten passwords, or cancel their account with you
This site demonstrates how a security ssuite (login/logout with user-supplied credentials that permits users to update their content with password-protection) will be a basic hinderance to spammers, spoofers or malicious hackers.
However, as in all cases, user awareness is also necessary to prevent a malicious attack on your site. For instance, don't click directly on any links that appear in suspicious emails, no matter how 'real' the site appears. Most respectable vendors will not ask for your pin, SSN or other persoanal information by email. It is always best to email or call them directly if there is a question or a concern.
