Integral analysis of privacy and security of online advertising networks
Online advertisement and its dangers
Online advertisement has become a major economic sector at the order of billions that all major websites and mobile applications rely on. Even though private users do take notice of online advertisement as an unwelcome annoyance, they seldomly are aware of how it puts their privacy and security in danger. Online advertising networks use online profiling as a basis for target marketing and collect information provided by cookies, web site traffic analysis as much as personal information of a users’ browsing and buying habits. Those online profiles often contain sensitive personal information, including medical histories or political beliefs.
Ad networks can also fall prey to misuse by so-called „malvertising” attacks - malicious advertising, meaning the injection of malware into regular and legitimate online advertising networks. Online ads can therefore be the source of malware, initiate link-hijacking or trick users into voluntarily installing malware or subscribing to expensive services. Advertising content offers an ideal opportunity for attackers to insert malware into reputable, high profile websites and mobile applications.
PriSAd research goals
Previous research projects have shown how widespread of a phenomenon malvertising has become, without however taking into account mobile applications. PriSAd aims at an integral analysis of security and privacy in the context of online advertising networks and wants to further evolve and promote automated malware recognition. As long-term goal, PriSAd wants to provide online services with malware recognition to help protect their users from harmful online ads.
