Here's an article worth reading if you use WordPress on any of your accounts.
I would highly recommend you login to your WP at least once a week to run any updates. I've been seeing a lot more compromises of WP sites lately than in the past. A lot of this is likely due to popularity but I often come across installs that are many versions behind the current releases. Wordpress is fantastic when it comes to releasing updates and fixes (and they're incredibly easy to run with just a few clicks) but they don't help if you don't log in regularly to run them. :)

Research from security vendor Checkmarx revealed that 12 of the top 50 plug-ins for the WordPress platform are susceptible to attacks such as SQL injection and cross-site scripting.
A new study has found that roughly 20 percent of the 50 most popular plug-ins for the WordPress platform are vulnerable to common Web attacks.
According to research from security vendor Checkmarx, that figure represents nearly 8 million downloads of plug-ins vulnerable to issues such as SQL injection, cross-site scripting, cross-site request forgery and path traversal. Additionally, the research revealed that seven out of the top 10 most popular e-commerce plug-ins for WordPress are vulnerable to attacks as well—translating to more than 1.7 million downloads.
