WordPress blogs falling prey to worm
A worm is circulating that posts spam and malware to some blogs using old versions of WordPress. The organization recommends all users upgrade immediately.
A worm is circulating that can post malware and spam to some WordPress blogs using outdated versions of the blogging software, according to a post by Matt Mullenweg, founding developer of WordPress.
The vulnerability allowing the attack was discovered August 11, at which point WordPress encouraged users to upgrade to version 2.8.4. However, many people have yet to upgrade, and reports online indicate the worm is making dubious progress by the hour.
The worm does not affect the current version 2.8.4 and the one prior to it. And it only affects people who host their own WordPress blog. Blogs hosted on WordPress.com are unaffected.
