A few weeks ago we talked about cyber-criminals using Digg.com to spread malware. Today we see that the very same group responsible for the Digg.com incident was using the same tactic on YouTube through the use of YouTube's Annotations feature. Video Annotations is a way to add interactive commentary to videos on YouTube.
The following image displays a video using the annotations feature to guide users over to a malware ridden website:
Although the YouTube description malware is not as prevalent as the Digg.com comment abuse, it does show that Social Media websites are increasingly being used to spread Malware. We expect to see plenty of new examples similar to this throughout 2009.
