WordPress.org has just posted the following on its blog:
“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.”
According to founder Matt Mullenweg, WordPress .org has decided to reset all WordPress.org, bbPress.org and BuddyPress.org passwords, because of suspicious activity surrounding popular plugins AddThis, WPTouch and W3 Total Cache.
