Researchers have shut down an "Expansive" ad fraud scheme that spoofed more than 1,700 applications from 120 publishers and impacted roughly 11 million devices.
The includes the bundle IDs that belong to legitimate apps so as to conduct what's called as an app spoofing attack, in which a fraudulent app passes off as a highly-regarded app in an attempt to trick advertisers into bidding for the ad space.
The takedown of VASTFLUX arrives three months after the disruption of Scylla, a fraud operation targeting advertising software development kits within 80 Android apps and 9 iOS apps published on the official storefronts.
VASTFLUX, which generated over 12 billion bid requests per day at its peak, is only the latest in a stretch of ad fraud botnets that have been shuttered in recent years, after 3ve, PARETO, and Methbot.
