We have received a sample of a Symbian
malware that exhibits the same behaviour as of the SYMBOS_COMWAR
family.
The first generation of the malware arrives as one of the files
inside a pirated copy of SymCommander software. SymCommander is a
file management software specifically used for Symbian
phones.
The actual malicious file inside the pirated copy of SymCommander
SIS package is named cwoutcast.exe. Just like the other
SYMBOS_COMWAR variants A and B, it also propagates through MMS by
sending a copy of itself as a .SIS installer. It also propagates
through Bluetooth by sending itself in a randomly generated
filename.
It is also noticeable the embedded string on the cwoutcast.exe as
qouted below.
