Is your WordPress blog updated?
Sometimes, it takes a huge/serious security alert like the one we have now with WordPress to force people to upgrade their blogs to the latest secure version.
I’m pretty sure most bloggers out there are already aware of the latest growing incidents of WordPress hacking. As always, the old versions are the ones affected and even if you thought you’re always updated, don’t forget the other less important blogs and the subdomains you’ve set up before but abandoned. They could the doorway to hacking your main blog.
WordPress has that built-in system to alert you if ever you’re not updated (WP 2.8.4 is the current/latest version) and there’s also that automatic upgrade feature that makes it easier to do so. Just go and hit the upgrade button and spare yourself a lot of headaches later on.
