This morning it appears as though YouTube has been the subject of a malicious attack, with HTML in comments being used to insert code into video pages.

The good news? The hacker only seems interested in targeting Justin Bieber videos.

The hack employs a number of generally harmless exploits, such as showing javascript alerts and pop ups and redirecting users to other websites.

One pop up falsely claims Justin Bieber has died in a car accident, and recommends users check cnn.com for more information.

YouTube is deleting comments in an attempt to alleviate the problem while security is beefed up. The hack is allegedly the work of members of the 4chan bulletin board community, with a message being posted this morning stating “Remember this day. Today is a reminder that we can still shake the foundation of the internet.”.
