This new symbian malware is similar to other symbian malware in the sense that it overwrites normal files in the system in order to destroy them. However, it has a particularly interesting characteristic where it attempts to spread infection to a computer running in Windows OS. This is because this malware drops these 4 files into the E: directory (which is the memory card):
Thus, when the memory card is inserted into a Windows computer, the file autorun.inf will attempt to execute fsb.exe. Also, the file SYSTEM.exe may not have an automatic startup routine, but since it has the icon of a folder, this could be executed by an unsuspecting user who wants to open this “folder”.
Note: This malware will be detected as SYMBOS_CARDTRP.A
Dropped Files
fsb.exe – BKDR_BERBEW.Q
buburuz.ICO – Icon file for the memory card
autorun.inf – file used to automatically execute fsb.exe
SYSTEM.exe – WORM_WUKILL.B
buburuz.ICO – Icon file for the memory card
autorun.inf – file used to automatically execute fsb.exe
SYSTEM.exe – WORM_WUKILL.B

Update
Previously, we have come to define an example of a “blended threat” as a Windows worm that either spreads via multiple propagation vectors such as email, IM, network shares and application vulnerabilities and/or a worm that has capabilities of other malwares such as file-infectors, backdoor trojans or even spywares.
Now, we may see a slightly new encounter of another implementation of what a “blended threat” is or could be in the near future – a mobile malware that has the capability to affect the Windows platform!… Ergo, let the battlecry linger on – Let’s continue to be vigilant!
As Raimund Genes, Trend Micro Chief Technologist Anti-Malware has said. “As mobile threats continue to evolve, it’s likely that we will see further attacks similar to this, but utilizing more robust propagation techniques and therefore carrying a higher potential for infection.”
