Researchers have uncovered a huge network of fake apps running fake ads, mainly on iOS devices.
The operation was named ‘Vastflux’ in reference to its use of the Video Ad Serving Template specification, as well as the fast-flux technique to change masses of IP addresses and DNS records to hide the malicious code within the fake apps.
Cybersecurity Team HUMAN discovered Vastflux during an investigation of another ad-fraud network, finding that it generated over 12 billion ad bid requests a day and affected over 11 million devices, most of which were iOS.
