With “GM-Bot” Malware not done terrorizing
the world of Android phone, another malware had been discovered that
potentially inflect damage to Android-base smartphones. This new Trojan malware
is targeting any Android smartphones to risk about 60%.
Those Android smartphones running
4.4.4 or the earlier version of the Android OS will have greater risk. This kind
of malware propagates on application that user downloaded or install from the
untrusted sources.
The name of this new malware is “Triada”,
which is a windows-based malware in terms of complexity, according to
Kaspersky.
According to a junior analyst of
Kaspersky Lab named Nikita Buchka, “It is stealthy, modular, persistent and
written by professional cybercriminals. Triada operates silently, meaning that
all malicious activities are hidden, both from the user and from other
applications. These apps can sometimes be found in the official Google Play app
store, masquerading as a game or entertainment application. They can also be
installed during an update of existing popular applications and are
occasionally pre-installed on the mobile device.”
Kaspersky, tells that about
eleven known mobile Trojan malwares uses a root privileges. The three of them includes
Ztorg, Gorpo and Leech, which are cooperating to each other. Smartphones that
are infected on these malware are organizing to make a network, which will
create an advertising botnet to threat user to install different kind of
adware.
According to Buchka, after the
android smartphone had been rooted, those Trojans (above-mentioned) will then
download and install a backdoor. After that, it will download and activates two
module that have abilities to download, install and launch applications. Also Buchka,
added that this type of Trojans will use a Zygote process to implement the code
in context in all apps in that particular Android.
When the Android smartphone is
being infected with this type of Trojan malware it is very difficult to get rid
of this.
Once the Android smartphone is
infected, it will penetrates on almost running processes and thus continues to
exist at memory only. Those all running processes that are infected with Trojans
will be hidden to user and other applications. This means that, detection and
removing of this Trojans via antivirus will be very difficult.
The most effective solution on
this problem when being infected is to a complete wipe or to do a reformat of
the Android device.
