You’re probably wondering why. It’s not to increase your feed reader numbers (is 1 going to make that much difference?!), and yes it’s already a good idea anyway to check that your posts are coming through correctly and without display problems. However to me now, the main reason is because of this spate of hacking and injecting hidden links into posts. By subscribing to your feed in something like Google Reader, which displays the feed with little additional formatting, you can see these additional links instantly. It’s a WordPress vulnerability that’s affected users of older versions (2.5 and possible 2.3.3 are okay as far as I’m aware) but of course these hackers will continue to try and find a way to exploit the latest version too.
A friend of mine was recently hit, I only noticed when I read his latest post and saw a long list of links to spam and adult sites. On checking his site they weren’t visible, but they were still there. I upgraded his blog to 2.5 for him and had a look through the last 5 posts he’d made. The last post, which was just 24 hours old, already had one injection of links. Older posts had 4-5 different injections, which contain about 50-100 links each. That’s a lot of links. Clearly different injections coming in from different people.
I’m sure some of these injections can go unnoticed in a feed as well, and of course there are other areas of your site that could be vulnerable if you’re not running a currently secure version, so a brief check of your source code every so often will be a good idea too, but this is just one additional step that’s easy to do. So go subscribe now 😉
