There is a new Symbian malware that has been
found to be a trojanized version of a Symbian application called
InstantSis.
InstantSis is created by Biscompute and has the capability of
transferring software from mobile phone to another mobile phone or
to a PC.
This Symbian trojan is the first of its kind because it
particularly targets the phone’s MMC card. It sets a randomly
generated password to the card thus making the card inaccessible
once the phone has been rebooted not unless the correct password
has been provided. It also deletes system directories thus losing
user data (installed applications, MMS and SMS messages, phone
numbers, etc) and other critical system data.
It has greater damaging effect on phones that uses Symbian OS 8.1as
because they cannot recover deleted system directories on reboot as
compared to Symbian OS 7.0s and earlier.
We are still acquiring for the sample of this new Symbian
malware.
Just an update:
The virus report for SYMBOS_CARDBLK.A has already been posted. You
