eScan warns of Self-Replicating Worm that Infects Android Smartphones


MUMBAI, India – July 21, 2014 – eScan, one of the leading Anti-Virus and Content Security Solution providers, warns users of an Android worm that spreads through text messages. A virus known as ‘Andr/SlfMite-A’ has been recently discovered that is spreading throughout the Android world through text messages (SMS). People are not really suspicious of text messages that they receive from known numbers and the virus is apparently playing with this trust.

Andr/SlfMite-A virus sends SMSs, which includes a malicious link. If you unknowingly click on the embedded link within the SMS, then the virus easily get installed on your phone. Once the virus is downloaded onto your phone, it secretly sends text messages with malicious link to the first 20 contacts from your contact list. This is how the message looks like:

These kind of self-replicating ‘worms’ send SMSs to your contact list, thus playing with the trust that the receiver has in you. Just because the person from your contact thinks that the message is from you and hence is a genuine text message, they might just get tricked into clicking the link and unknowingly allow the virus to get installed onto their phone.

Surprisingly, Andr/SlfMite-A also shows up on Windows systems. When this malware gets downloaded onto the computer, it alters the browser settings, so that when you enter a search term, it automatically redirects you to a malicious websites. It also makes changes in the registry and system files so that it can remain undetected.

When it comes to SMS’s, why are such attacks more dangerous?

  • As criminals directly attack the Smartphone of the user, it becomes a highly personalized attack.
  • Users generally respond to an SMS quickly as compared to an email.
  • As it is a personal device, user may also have stored his/her personal information such as account details or credit card info on his/her Smartphone, for handy usage and quick transactions. This may also put user’s personal information in danger.
  • Such attacks can be executed easily as minimal interaction is required for SMS phishing attack.

Fortunately, there are ways you can combat it. eScan suggests few tips that can keep you safe from such self-replicating ‘worms’.

  • Always have anti-virus software installed on your Android Smartphone.
  • Never download any application in Android from untrusted source. It is recommended that you only download apps from Google Play.
  • Always be cautious about opening any suspicious looking SMS web-links. It is advisable to never click on links sent through SMS.
