WordPress.org forces users to change passwords

On Tuesday (June 21, 2011) WordPress.org announced it was forcing users to reset their passwords after several popular plugins were compromised by hackers. AddThis, WPtouch and W3 Total Cache were identified as being the plugins affected. These new versions were rolled back and pushed them out as updates very quickly.
This doesn’t affect WordPress-powered blogs, but does affect WordPress.org forums, trac and code commits to plugins or themes. WordPress.com had its own issues earlier this year when it was the victim of a low-level root access breach in April.
Earlier today the WordPress team noticed suspicious commits to several popular plugins (AddThis, WPtouch, and W3 Total Cache) containing cleverly disguised backdoors. We determined the commits were not from the authors, rolled them back, pushed updates to the plugins, and shut down access to the plugin repository while we looked for anything else unsavory.
We’re still investigating what happened, but as a prophylactic measure we’ve decided to force-reset all passwords on WordPress.org. To use the forums, trac, or commit to a plugin or theme, you’ll need to reset your password to a new one. (Same for bbPress.org and BuddyPress.org.)
They also offer standard good advice:
As a user, make sure to never use the same password for two different services, and we encourage you not to reset your password to be the same as your old one.
Second, if you use AddThis, WPtouch, or W3 Total Cache and there’s a possibility you could have updated in the past day, make sure to visit your updates page and upgrade each to the latest version.
