Web advertisements are one of the more pesky ways malicious hackers have been using to steal all manner of private information or deliver other sorts of malware.

Due to the dangers of rogue ads, publishers are in great need of an active, technological approach to protect themselves and end users accessing those ads, said Mike Ter Louw of the University of Illinois at Chicago, Department of Computer Science at the Usenix Security Symposium this week. Web publishers frequently integrate third-party advertisements into web pages that also contain sensitive publisher data and end-user personal data. This practice exposes sensitive page content to confidentiality and integrity attacks launched by advertisements, he said.
