Schneier - Android Ad-Fraud Scheme

BuzzFeed is reporting on a scheme where fraudsters buy legitimate Android apps, track users' behavior in order to mimic it in a way that evades bot detectors, and then uses bots to perpetuate an ad-fraud scheme.

After being provided with a list of the apps and websites connected to the scheme, Google investigated and found that dozens of the apps used its mobile advertising network. Its independent analysis confirmed the presence of a botnet driving traffic to websites and apps in the scheme. Google has removed more than 30 apps from the Play store, and terminated multiple publisher accounts with its ad networks. Google said that prior to being contacted by BuzzFeed News it had previously removed 10 apps in the scheme and blocked many of the websites. It continues to investigate, and published a blog post to detail its findings.

The company estimates this operation stole close to $10 million from advertisers who used Google's ad network to place ads in the affected websites and apps. It said the vast majority of ads being placed in these apps and websites came via other major ad networks.

Lots of details in both the BuzzFeed and the Google links.

The Internet advertising industry is rife with fraud, at all levels. This is just one scheme among many.
