Android Ransomware

Android Ransomware is rising and it spreads as a simple virus which disables the phone and demands a ransom to unlock the phone. Users browsing unsafe domains are more exposed to the risk of their phone being infected by the malware. As per reports, cyber attacks on Android have increased more than 40 percent from 2016 to 2017, which is an alarming signal.

How Android Ransomware Enters a Mobile

 Websites like gambling or pornography are often targeted by cybercriminals to insert malware. If you happen to visit these websites and click on any malware-infected link, the virus may enter your smartphone easily.

 Many 3rd party app stores do not have strict guidelines for app submission. Hence, hackers can easily add fake apps infected with malware in these websites. Downloading these apps, one can easily become the victim of Android Ransomware.

Upon installing any malicious app, you will get a pop-up message that usually asks to install any additional application or change the settings of your mobile. As these messages look like any normal message, users may be easily deceived.

If you tap on ‘I agree’ and ‘Continue’, you will grant the malware the admin right of your phone. Known as Clickjacking, this is a method of gaining user’s consent without letting the user know the motive behind seeking the permission.

What Happens after Ransomware Enters a Mobile Phone

After gaining the access, the Android virus encrypts all data stored in the smartphone and makes it non-functional.  You may receive a threatening message stating that service to your device has been suspended and all your personal data are encrypted. The reason for blocking this service is surfing on pornographic or illegal websites.  The message also states that to resume access to your data, you need to pay a penalty of 500 rubles. Failing to pay this ransom, your entire browsing history will be made public and sent to your contact list.  Any attempt to unlock the device will result in complete loss of all important information such as photos, videos or documents.

Apart from this, Android ransomware can change the passcode or PIN of your phone.

How to Remain Safe from Android Ransomware?

Android ransomware is constantly becoming more dangerous as hackers are updating the program continuously. Some of the tips to remain safe from this ransomware includes:

  • Email attachments from unknown sources must be opened with caution.
  • Do not click on links in SMS or MMS messages without verifying the sender.
  • Even if you receive an email from a trusted company, check the sender address
  • Do not install apps from 3rd party websites other than Google Play Store.
  • Use an antivirus software for Android and keep it updated.
  • Do not randomly connect with WiFi as these may be smart traps of hackers.
