F-Secure has detected 2 new Symbian Viruses, named Locknut.B and Drever.A respectively. Both viruses are malicious and effect the phone by disabling them.
Locknut.B is a malicious SIS file trojan that pretends to be patch for Symbian Series 60 mobile phones. When installed Locknut.B drops a binary that will crash a critical System component, that will prevent any application from being launched in the phone. Thus effectively locking the phone.
Drever.A is a malicious SIS file trojan that disables the automatic startup from Simworks and Kaspersky Symbian Anti-Virus softwares. Currently it is still unverified whether either of these softwares have protection against such attacks.
It seems the world of mobile phones should start to brace itself for even more malicious viruses which may appear. The trend of new viruses seems to be inevitably growing.
