A search of sites hosting cracked versions of apps for Symbian phones has unearthed 52 "previously unidentified Trojans", according to New Zealand-based mobile anti-virus specialist Simworks. Other anti-virus experts reckon that the infected files found by Simworks are more properly described as repackaged versions of previously identified malware.

The malicious files found by Simworks pose as popular applications and games such Bitstorm, BugMe Cosmic Fighter, 3D Motoracer, and Splash ID. In addition to the installation files for the app itself, the files include various versions of previously known malware such as Cabir and Locknut. There are no reports of any of the new Trojans in the wild.

Simworks chief exec Aaron Davidson said, "It would be easy for a malware author to create one 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."
