More than 11 million people have become part of an ad-fraud scheme, without realising, a new report has revealed.
Their phones have been attacked by a malicious scheme called Vastflux.
The attack spoofed 1,700 apps and targeted 120 publishers, Wired first reported.
The criminals behind the operation were requesting a staggering 12 billion adverts per day.
The organised attack was uncovered by the cyber firm Human Security.
