Hacked!? Not So Much: Your WordPress.com Account and Security

This past weekend a number of WordPress.com users discovered that a spam post promoting a “make money from home” scheme had been published on their websites without their prior knowledge or consent.  Many of those sites had not posted for some time while others had recently posted. What was common to them all, apparently, was the use of the same password for both their WordPress.com site as well as on other sites they logged into and which had been cracked.

Pete Davies, who works for WordPress.com, posted this response in the Community forums:

Thanks for letting us know about this. We also noticed something suspicious. We have reset the passwords of all affected users and have sent them an email to let them know. If there was any spam posted and not removed before we got there, we also went ahead and cleaned that up.

It is very likely that you were using the same password on WordPress.com that you used elsewhere. Recently, a few large services — LinkedIn, Yahoo, eHarmony, and Last.fm to name a few — have suffered well-publicized security breaches that have exposed email addresses and passwords. Although the passwords are usually stored securely, simple passwords can be decrypted or “cracked” in a matter of hours using modern technology.

Hackers gather the lists of email addresses and passwords from these services and then try to use them to access accounts on other popular services, like WordPress.com. If you used the same password multiple places, then your account can be compromised. That is what happened here. We do have measures in place to protect password guessing or “brute force” attacks but in this case, since the password is known beforehand, there is no need for a hacker to guess.

You should have a strong, unique password for every account you have on the internet. We have some more information on selecting a strong password in our Support section, please read through it:

We take security seriously, and are happy to answer any questions you have.

The importance of having a unique password for every internet site you log into cannot be stressed enough and, if you use a public computer (at work, the library or at university) to connect to the Internet, the importance of logging out of those sites and clearing the browser’s cache and cookies each and every time is equally important.
