Android malware
and viruses
Android based
malware is a new threat that affects countries all over the world. One of the
most popular forms of Android malware belonging to the ransomware category of
infections, uses torjan horses to lock an Android phone, encrypt files on the
SD card, and display a screen that attempts to persuade victims to pay a ransom
in order to unlock their phones and/or decrypt their files; However, there is
no actual easy procedure to retrieve encrypted files.
If you have
received a message on your Android phone claiming to be the Police, FBI, or
other establishment, please note that you are not in any trouble. This is a
very common scam similar to the FBI virus we are credited with discovering in
2012 and paying the fine will not help.
Other Android
malware is found in the scareware or rogue software category. These programs
may promote themselves as legitimate Antivirus solutions for Android
smartphones, but instead they primarily siphon user information and files saved
on the phone’s SD card. Some of these programs are defined as proof-of-concept
apps that have not yet been identified by Google and can even be found in the
Google Play App store.
How does an
Android phone get infected with malware?
There are many
ways an Android Smartphone can become infected with malware and viruses:
•Some malicious Applications are available
in the Google Play App store, including fraudulent games. These apps look for
images, documents and videos to encrypt. After encrypting the files the apps
will then rename their file extensions to .enc. The apps have a C&C
(command and control) server on the TOR network and collect information about
the phone (IMEI, OS, phone model, manufacturer) to send to C&C server.
•Text spam containing malicious links.
•Email spam containing malicious links.
•Advertisements on questionable websites.
How to remove
malware from Android Phones
There are no
current easy solutions to retrieve encrypted files associated with Android
ransomware infections; However, there are security applications that can
potentially block an attack from occurring like Mobile Security & Antivirus
by ESET (found at bottom of page: ESET Online Store – All Products – Save 25%)
and Kaspersy Internet Security for Android
In some cases an
Android user can simply uninstall the unwanted program through the common
uninstall
procedure based on the model of the smartphone
