New mobile threat Commwarrior.T |
 Commwarrior.T Commwarrior.T is a new variant of the Commwarrior worm that is based on Commwarrior.Q. Unlike most Commwarrior variants, Commwarrior.T is a recompiled version that contains new functionality. Commwarrior.T affects only Symbian Series 60 phones that use Symbian OS
version 8.1 or older. This means that the latest model of phones that
will be affected is the Nokia N72. Phones using Symbian OS 9.0, such as
the Nokia E70 or 3250, will not be affected.
This variant of Commwarrior, enumerated as T, was otherwise quite
uninteresting apart from the fact that it is newly compiled from the
original source ??€� unlike most variants. The author refers to it as
"Commwarrior v3 Lite" in his code. In the mean time, we already have
the detection published and we've updated our free F-Commwarrior
utility that you can download from F-Secure Mobile Anti-Virus
if you suspect your phone has been infected.
Commwarrior.T is very similar to Commwarrior.Q.
Currently the only significant difference appears to be the T variant
uses more stealth by not advertising its presence on the infected
device.
F-Secure Mobile Anti-Virus for Symbian detects this malware starting from the update build number 119.
