Computers do not have a built-in billing system. Phones do: it's called the phone bill. We have just now seen the first examples of money-making malware that infects smartphones. This talk will provide details of the smartphone trojans that either place calls or send text messages to expensive premium-rate numbers.

The most interesting part of these new attacks are the phone numbers they are using. For various reasons, they cannot effectively use regular premium-rate numbers. Instead, they use unusual phone numbers in far away places - like Somalia, North Korea and the South Pole! How does this work? How do the virus writers route the money back to them without getting caught? And what can we do about this before it gets worse?
