Compromised Word Press Blogs: A Phisher's Paradise

Summary: Cisco Talos reports that over 5 percent of the phishing and malicious emails it collected over roughly a month contained links with WordPress-related URLs, using compromised blogs as staging points for Blackhole and other exploit kits. A Verizon Wireless monthly statement phish pointed to a /wp-content/uploads/fgallery/vz.html URL that the sandbox confirmed as Blackhole, prompting new rule SID 23171 alongside the earlier SID 21941 for PHP files in the Fgallery directory.

Why it matters: A Google query for "wordpress file upload vulnerability" returns 459,000 results, with live exploits on the first several pages, so an unpatched WordPress install is a ready-made entry point for anyone running a phishing campaign.
