Android botnet may net millions yearly for its operators

Researchers from Symantec and North Carolina State University may have stumbled upon one of the largest and most lucrative mobile botnets yet.

First discovered by N.C. State researcher Saxon Jiang and then confirmed by Symantec, the botnet consists of of hundreds of thousands of infected nodes, said Cathal Mullaney, a Symantec security response engineer, in a blog post.

The malware used to grow the bot is being served on close to 30 rogue applications, available for download in third-party Chinese markets, not the official Android Market, Mullaney said. Once a phone is botted with the trojan, dubbed "Android.Bmaster," it is used to send out premium-rate text messages, make premium phone calls or connect to pay-per-view videos.
