Matt Mullenweg noticed a few days ago that suspicious code had been added to popular plugins such as AddThis, WPtouch, and W3 Total Cache. The code added backdoors that would allows hackers access to your website.
As a precaution they have reset all passwords on WordPress.org so if you want to post something in the support forums or bug tracker you will need to reset your password.
The malicious code has been removed from the plugins therefore if you use any of these plugins and have updated over the last few days, it’s important that you upgrade them.
