Almost 30,000 videos on YouTube contain comments with links to a malicious Web page

This is yet another example of how cyber-criminals are attacking popular Web 2.0 sites to distribute malware. Such attacks have previously been seen, to a lesser extent, on sites including and Facebook. Now, PandaLabs, Panda Security's malware detection and analysis laboratory, has detected up to 30,000 videos on YouTube with comments containing links that point to a Web page designed to download malware.
