SQL injections are one of the fastest-growing and most threatening security concerns for websites and blogs alike. Not only is an SQL injection one of the easiest attacks that can be launched on a server, it’s also one that leaves your website data and personal information vulnerable.
And you may not even know you’re a victim until it’s too late.
Hackers can exploit this vulnerability in several ways without your knowledge. They can insert hidden links to spyware, adware and viruses. Google picks up that your site could be a risk to other users, and puts up a “This Site May Harm Your Computer” warning. You lose your hard-earned visitors, rankings and revenue.
It’s even possible that your web hosting company was the victim of the hacking, and it spread from site to site across the entire server.
What are the Symptoms of a Blog SQL Injection?
You may not even realize there’s a problem with your blog if you don’t regularly login to Cpanel, FTP or other website management systems outside of WordPress. In fact, you may find out about the hacking
- From a web-based security scanner like McAffee SiteAdvisor or Norton SafeWeb
- From Google’s diagnostic database, which can tell you if any spyware attacks have been coming from your site within the last 60 days (check your own site by replacing the EXAMPLE.com with your URL by clicking here)
- From the search engine result pages which come up with strange links or pages when you search for your own URL. An example might be searching for your site and seeing pharmaceutical links inside.
- From your visitors themselves who report getting a virus (or being redirected to a spyware site) when they visit your page.
Prevention is the First Step
The best way to protect your blog against SQL injections is to make it as inconvenient and difficult as possible for the hackers to get in.
This includes obvious things like not using “admin” as your login name (if your WordPress was setup this way, you can create a new user, give them administrative privileges and then move your “admin” posts over to your newly created username), setting a strong password and storing it in a safe location (I use Roboform and love it), and updating both your WordPress installation and your plugins as soon as new releases are available.
There are some helpful plugins that make blog management and protection easier too – but keep in mind, the more plugins you have installed on your blog, the more you could be leaving it vulnerable to being exploited, as plugin authors don’t always keep their work up to date.
