1.New University of Washington research finds that for a budget of roughly $1000, it is possible for someone to track your location and app use by purchasing and targeting mobile ads. The team aims to raise industry awareness about the potential privacy threat.
“Anyone from a foreign intelligence agent to a jealous spouse can pretty easily sign up with a large internet advertising company and on a fairly modest budget use these ecosystems to track another individual’s behavior,” said lead author Paul Vines, a recent doctoral graduate in the  Paul G. Allen School of Computer Science & Engineering.

2.The team also discovered that individuals who purchase the ads could see what types of apps their target was using. That could potentially divulge information about the person’s interests, dating habits, religious affiliations, health conditions, political leanings and other potentially sensitive or private information.

3.On the industry side, mobile and online advertisers could help thwart these types of attacks by rejecting ad buys that target only a small number of devices or individuals, the researchers said. They also could develop and deploy machine learning tools to distinguish between normal advertising patterns and suspicious advertising behavior that looks more like personal surveillance.

4.The University of Washington team demonstrated that customers of advertising services can purchase a number of hyper-local ads through that service, which will only be served to that particular phone when its owner opens an app in a particular spot. By setting up a grid of these location-based ads, the adversary can track the target’s movements if he or she has opened an app and remains in a location long enough for an ad to be served — typically about four minutes, the team found.
