Best Solution For Kristina Ransomware Removal From Windows System

Complete Information on Kristina Ransomware

 

Cyber security experts have revealed the new version of Crypt12 Ransomware known as Kristina Ransomware reported on August 15th, 2017 for the first time. The name of this malware is based on the ransom note identified as 'KristinaSC L1.0' which is displayed as a program window onto the affected computer screen after it successfully encrypts the targeted files stored onto the system. Although, this file-encoder virus made an appearance onto the radar of security vendors on 2nd November 2017 which is almost 2 months after the development and releasing data of this actual malware. The criminal hackers behind Kristina Ransomware continue to use malicious spam email campaign in order to infect the targeted computers and also uses macros to install the threat silently onto the machine.

This newly detected ransomware is not very different from the previously detected Crypt12 Ransomware and the source code used in this malware is also very similar to the older one. Moreover, the threat uses the same file extension i.e. 'crypt12' in order to append the affected file name encoded by Kristina Ransomware. The files that have been enciphered by this malware features a custom marker which follows the model noted as '[victim’s-id]-[developer’s-email].crypt12'. For example 'Lisa-vls.doc' might be renamed with '[email protected]'. Based on the latest investigation report, it mainly targets images, eBooks, spreadsheets, presentations, audio, Office documents, videos and databases for their successful encryption. Once it encodes the targeted system files, it displays a program window titled 'KristinaSC L1.0' onto the affected PC screen which is reported as a ransom notification that asks the victimized users to pay a specific amount of ransom money to get the enciphered files back.

Do You Need To Pay Ransom Money?

According to the malware researchers, Kristina Ransomware is reported to run as an executable file i.e. 'KristinaCS.exe' on compromised machine. After the successful encryption, the operators of this threat suggests the affected users to write an email to the email address '[email protected]' provided in the displayed ransom notification. However, the threat has the ability to delete the Shadow Volume Copies of encrypted data that Windows keeps in case if the users need to restore some of their files. Most importantly, the security experts strongly suggests the compromised PC users to refrain paying ransom money to the con artists, instead delete Kristina Ransomware as quickly as possible and recover their vital files using backup copies or third party data recovery tool.
