Fraud in this Russian-owned app targets US election swing states ...

A ad fraud scheme dubbed Matryoshka is preferentially targeting U.S. swing states in a reportedly Russian-owned mobile app that has historically been linked with white supremacism content, according to an ad fraud vendor. Matryoshka, of course, are nesting Russian dolls. The theft is of both advertisers’ dollars and users’ private data, mostly in the United States. Data that the Matryoshka fraud scheme targets is location data including longitude and latitude, device identifier data, and IP address, which can connect you to a specific neighborhood or even exact location. And while key U.S. swing states such as Pennsylvania, Michigan, and Wisconsin account for less than 10% of the activity in the affected app, they make up 35% of the attacks.
