Yesterday a handful members of internet community 4chan hacked YouTube and targeted the videos of pop singer Justin Bieber, although some other videos were also hacked. Some users claimed that they saw a pop up saying that Bieber is dead.

It seems that You Tube had a vulnerability which allowed the members of 4chan group to inject html directly into the webpages and execute it. For a few hours You Tube was the host of a variety of malwares, pop up messages and pornographic videos.

Google later reported “We took swift action to fix a cross-site scripting (XSS) vulnerability on youtube.com that was discovered several hours ago. Comments were temporarily hidden by default within an hour, and we released a complete fix for the issue in about two hours. We’re continuing to study the vulnerability to help prevent similar issues in the future.”
