Click fraud isn't the only malicious online activity advertisers need to keep an eye on. Video as a promotional advertising tool will begin to attract more mischief by those who want to exploit the
Web and its content.
Hackers exploited a cross-site scripting (XSS) vulnerability on Google's YouTube Sunday, hitting sections where users post comments, according to Network World, an IDG News site. The hack focused on clips related to pop star Justin Bieber. It didn't
involve malware, but the code did affect YouTube pages so visitors saw tasteless messages or redirected to external sites with adult content.
