It is technically a YouTube link, but it is redirecting to securitytube.net. I know this because the Internet I am on blocks YouTube, but not SecurityTube, so going directly to the redirect link works, but the YouTube link does not.

At least that is what my browser says:

http://www.youtube.com/redirect?username=digitalhook&q=h...

Looks like someone found a YouTube exploit.
