Recently, we’ve been seeing more and more WordPress sites maliciously “hacked” because our customer chose a weak password like “admin”, “password”, “temp”, “test”, or “wordpress”.
If you use a password like this, “hackers” maybe able to guess it and login before rate-limiting stops them from guessing stronger passwords.
Hackers are using automated software to try to login to millions of WordPress sites every day with these passwords. Because so many sites are being compromised this way, we’ve taken the fairly radical step of blocking all WordPress logins that use them.

This post describes a significant change in the way Web browsers recognize certain kinds of SSL certificates. We’re making sure that all SSL certificates bought from us are compatible with this change, and most customers can ignore the rest of this post, which has technical details.

We’ve had a couple of people ask if our servers are vulnerable to the recent security bug in the bash shell, also known as the “shellshock” bug.
The answer is no. All copies of bash on all our servers were updated to a fixed (patched) version yesterday, within an hour of the news becoming public.
Update September 25, 2:58 PM: We’ve also applied a later, stronger version of the fix today. This will soon be announced as Debian Security Advisory DSA-3035-1 .
Update October 14: This process described below is complete. All the updates were installed, and we’re now using only Debian wheezy on all servers.
Over the last year, we’ve been slowly upgrading our servers from Debian Linux version 6 (codename “squeeze”) to version 7 (codename “wheezy”).
All the “prominent” software (such as the Apache Web server, MySQL, PHP, the Linux kernel, and so on) was updated months ago, one piece at a time, usually with individual announcements here on our blog. Any software with security or compatibility issues has also already been upgraded.
What’s left at the end of that process are many “minor” packages, each probably used by less than 1% of our customers. We’ll be upgrading the rest of these over the next 30 days.

WordPress 4.0 was recently released, and as always, we’ve updated our WordPress one-click installer to automatically install the latest version for new WordPress sites.
If you’ve previously installed an older version of WordPress, you should update it from within your WordPress Dashboard.
We strongly recommend keeping your WordPress installation up to date (and using unguessable passwords)! You should first update the active theme and plugins, then delete all inactive themes and plugins, and then update the core WordPress files.
We’ve updated the default version of the Ruby scripting language on our servers from 1.8.7 to 1.9.3.

Google is fairly aggressive about checking for malware on Web sites. When they find a site distributing malware, they make a note of the details and try to warn visitors.

The PHP developers recently released versions 5.4.31 and 5.5.15 that fix several bugs. We’ve updated PHP 5.4 and 5.5 on our servers as a result.

One of our customers asked if multiple domain names hosted with us are vulnerable to “website cross-contamination”, a nasty security problem that can happen at many hosting companies when two different sites share the same “account”.
The answer is no. We intentionally handle multiple hosted domain names differently from the way most hosting companies handle extra hosted domain names, avoiding the problem.
