The trojans appear to be hidden inside cracked versions of popular Symbian games and application.
SimWorks CEO Aaron Davidson says “This is a significant development as until now we've usually found mobile trojans two or three at a time at the most. It would be easy for a malware writer to create 1 trojan and give it 52 different names however this is not the case here where we have 52 separately cracked and infected applications. Somebody has gone to an awful lot of time and effort to turn these out”.The company reports that it hasn't discovered any of these 52 trojans in the wild yet.
