F-Secure are reporting, via their weblog, that they have discovered a new Trojan targeting Series 60 phones. The Tojan deletes key system files (which will prevent some phone restarting) and write a random password to the MMC (so you can not access data on the MMC). The Trojan pretends to be a pirated copy application (InstantSIS). As F-Secure state: 'Cardblock.A is not a threat to people who don't use pirate copied software'.
