Antivirus watchdog Sophos is reporting rogue Apache modules being distributed on several compromised mainstream websites including a Seagate blog. Sophos Labs reported that it has been tracking an infection of the Mal/Iframe-Al injection framework on the Seagate site for several months. Mal/Iframe-AL is a generic detection that causes malicious redirects from legitimate websites to sites that host an exploit known as "Blackhole." Per this story: Seagate was informed of the breach back in February, but so far, the company has failed to remove the malicious iFrame detected by Sophos as Mal/Iframe-AL.
The Mal/Iframe-AL code located on the Seagate Blog and reported by Sophos on March 15, 2013, is blocked by Sophos EndUser Protection. To guard against rogue code being downloaded to your computer, be sure that your OS is updated with all current security patches, and that you've updated the latest virus detection patterns for your antivirus / anti-malware protection clients.
