Keep your WordPress site from being hacked with automatic upgrades

Blog, , , ,

I’ve already written about what to do once your site has been hacked, but let’s talk a bit about hack prevention.

I think it’s fair to say that most people manage their own WordPress installation because they have some programming background and want a little more control than you get with a hosted solution like Blogger or WordPress.org.  Webmasters like you and me usually know a bit about security and how important it is to keep things up to date.  The problem is that every minute spent upgrading your CMS to the latest version is a minute not spent writing or running your business.

So you know you should download the latest patch, make backups, disable, plugins, install… but it’s already 1 a.m. and you need to meet clients in the morning, so you put it on the back burner and your site ends up hacked.  What’s the solution?  If you’re Technorati, the solution is to motivate bloggers a bit more by threatening to delist them.  I can understand their point of view.  But how about something a bit more positive – automation.

There are two ways I’ve automated WordPress upgrades.  One is through Fantastico, which is a really cool script management system that your web host should probably provide.  I’m giving up on Fantastico, though, because it takes a long time for it to notice updates.

The second way I just tried out recently is the WordPress Automatic Upgrade plugin.  I’ve tried it out on three blogs now and so far so good – it hasn’t skipped a beat.  This functionality really needs to be folded into WordPress itself – with 2.5, they added the ability to automatically upgrade plugins but it seems like most security holes lately are found in the WordPress code itself.

That plugin is WordPress-only, but I recommend doing some research to see if there’s something similar out their for your blog software or CMS.  Even if WordPress never has another security bug, there’s always Joomla, and Drupal, etc…

What I did when my site showed up as a bad link

Blog, , , , , , , , ,

This site is just a humble blog where I write a bit about programming, design, usability, and other topics I’m interested in. It’s nice that I get some readership and few few good comments now and again but I don’t have any real financial stake here, and I’m definitely not interested in trying to spam anyone, send them spyware, etc. So imagine my shock when I noticed that my blog comes up with a warning, “This site may harm your computer.”

This comes up in various places including Firefox 3 and Google searches.  Obviously no one is going to follow a link to my site with such a disclaimer. So where did it come from and what did I do to clear my sites good name?

The disclaimer comes from the findings of StopBadware.org, an effort that I had heard about in the past but hadn’t really looked into. It sounds like a great idea – it’s very difficult for users to investigate every single link they might click on, and some spyware and adware is hard to see before it’s too late. So Stopbadware.org is a sort of neighborhood watch for the web.

How did my site end up on the list? There are a number of possibilities, so the first step is to check StopBadware.org to see what they found. Follow this link to search for your URL. Make sure you search for your root domain, in my case jasonmorrison.net. Some subdomains or directories might show up with a report while others are still considered clean. This confused me for a while.

Once you see the details there it’s time to hunt for problems. If you have anything more than a simple, static site this can be more difficult than it might first seem. My site uses WordPress and allows user comments. A bad link to show up in a comment, or someone may have hacked the site using a known vulnerability. It looks like it was the latter in my case, but I’m getting ahead of myself. How do you find the bad link?

There are lots of tools to find incoming links to your site, but I’ve only found one so far that checks outgoing links, at Bad Neighborhood. Don’t blindly rely on this tool, but follow up on any links that you don’t recognize having put there yourself. I found a link in the middle of a post from a month or so ago to some spammy German site.

How did the link get there? I don’t think my site was hacked wholesale (or if it was, they were very subtle about it). More likely someone took advantage of my laziness as upgrading WordPress and used a known security exploit.

Now that we’ve found and removed the offending link and plugged any known security holes, it’s time to try to get the stigma removed. Follow the link to the StopBadware.org request for review page and fill out a request. If the badware report came from one of their partners, you may have to follow up with them as well. I’m still waiting to here back on my review, I’ll post an update when I know more.

Hopefully this has been helpful. Let me know if you have any questions or suggestions in the comments below.
