In October, the Zimperium zLabs team informed the community about GriftHorse, a massive mobile premium service abuse campaign that compromised around 10 million victims globally. In the pursuit of identifying and taking down similar financially motivated scams, zLabs researchers have discovered another premium service abuse campaign with upwards of 105 million victims globally, which we have named Dark Herring. The total amount of money scammed out of unsuspecting users could once again be well into the hundreds of millions of dollars.
