The latest in Android ransomware, called “Simple Locker” is essentially a lockscreen type of malware that affects all types of devices.

All users, whose mobile devices were affected by this ransomware are strongly advised to plug out their SIM cards and follow the instructions after this article.

Simple Locker Ransomware Distribution

This lockscreen malware may use fake app downloads through malicious emails sent out to the user’s account. The email subjects may be connected with something the user is likely to tap on, for example:

  • “New version of your game.”
  • “New PayPal app.”
  • “The mobile app you subscribed for.”

After downloading the app, and starting it, it locks the user’s screen displaying the ransom message.

Simple Locker Ransomware In Detail

As soon as simple locker has been activated it may immediately lock down the screen of the user. After it locks down your screen, you may enter the main menu of your phone but the app will open the ransom message seconds after your action.

The message itself is written in Russian, but directly translated, it means the following:

“Attention! Your phone has been blocked! The device has been blocked for the distribution of child pornography, zoophilia, and other sick things. To unlock your phone, you need to pay 900 hryvnias.
1.Find a payment fulfillment terminal, located in your proximity.
2.In it, locate Money.
4. Input 260 hryvnias and tap on ‘Pay’
Do not forget to take your receipt! After the payment has been conducted your device will be unencrypted in 24 hours. IN CASE, YOU HAVEN’T PAYED YOU WILL LOSE ALL THE DATA ON YOUR DEVICE FOREVER!”

This locking of the screen is particularly bad in case you have saved your contacts or important files on your phone, because the Ransomware may block it in case you connect via USB to your computer. It is a clear sign of the ever increasing spread of ransomware infections across different devices with operating systems. This is especially scary when we put into perspective “the internet of things”, while looking towards the future.
