Looked into the Android SpySMS torjan as they say it has infected 40k users phones. This Mobile Trojan is using SMS as C&C protocol the way IRC C&C were used by PC Trojans back in the days. Got me thinking that the reliable SMS protocol is a nice protocol to control the android bots. The way this app try to block anti-virus from running and the long list of banking apps it controls is rather interesting as this has historically been more adapted by PC trojans and malware.
