For example, a file 1.jpg would be renamed to 1.jpg.steriok, 2.jpg to 2.jpg.steriok and so on. The ransom note is displayed within RESTORE_FILES_INFO.txt file. It informs the victims about the files encryption and states that the decryption requires a private key that they have to purchase from the attackers.

It also states that the attempts to restore access to the files using third party tools will permanently damage them. To get the further instructions such as how much the decryption tool costs, where is to pay and so on, they are asked to establish contact to the crooks via the provided email address.

Usually, users can’t decrypt their files without right decryption tool. Those tools can be purchased only from the attackers behind the infection. However, this is also true that the victims often do not receive the decryption tool even after the payment.

Therefore, it is strongly recommended not to pay the ransom. Instead of this, you should think of data recovery alternatives. Existing backups are the best way to recover the files. But, not all users have the backup files available.

  • You should have strong backup of all files and data stored in your computer because some ransomware is designed to look for network shares and encrypt all files stored in your machine. You would do well to store data backups on secure cloud server with high-level encryption and multiple-factor authentication.
  • Ransomware type virus often relies on exploit kits to gain illicit access to a System or network. If you run outdated or obsolete software on your computer, then you are in risk of ransomware because the software developers are not putting out security updates anymore. To remove abandonware and replace it with software still being supported by manufacturer.
  • The cybercriminals behind ransomware attack are using former banking Trojan as delivery vehicle for ransomware. It relies on malspam to infect your System and get foothold on your network. Once it gain access to your network, it shows worm like behaviour spreading from System to System using list of common passwords.
  • You should be alert while surfing online and avoid installing freeware from unknown sources, stop opening attachments coming from unknown emails and click on ads or popup messages after double reading.
  • Don’t pay extortion money in case of attack. We recommended you to stop paying ransom and FBI agrees. Cybercriminals don’t have scruples and there is no guarantee you will get files back. By paying extortion money, you are showing cybercriminals that ransomware attack work.
