Cry128 Ransomware Shows up on the Web in 2017

Cry128 Ransomware has been brought to the security analyst’s attention in the beginning of April 2017. This ransomware is a new variant of the Russian-originated nasty CryptON ransomware infection, which started to appear in several security forums in December 2016. After analyzing the initial characteristics of this malware, the researchers quickly made the conclusion that it must be another version of HiddenTear ransomware project. So far, it has been reported that the threat infects targeted machine through Remote Desktop Protocol services, which allows the hackers to log into the server of victims’ computer and execute the malware processes.

Working Principles of Cry128 Ransomware

Once the operators of Cry128 Ransomware gain access to the compromised system, it will encode all the files stored on victim’s computer. However, the ransomware exclude C:\Program files, C:\Windows, and the user profile folder from the file encryption procedure. As a result, system boot operation and critical processes of the machine are not impacted. Depth-analysis on this malware reveals that it relies on the modified version of AES encryption algorithm which works on the 128 byte blocks and also with the 1024 bit keys in the mode of ECB. Moreover, this destructive computer virus will delete the computer’s recovery points, thus Shadow Volume copies cannot be used by the victims of Cry128 Ransomware in order to recover the files encoded by this malware. However, it does not contain the list of file that it encrypts. Once it locks the system files, it appends one of the following weird file extension:

  • .fgb45ft3pqamyji7.onion.to._
  • .id__gebdp3k7bolalnd4.onion._’
  • .id__2irbar3mjvbap6gt.onion.to._
  • .id-_[qg6m5wo7h3id55ym.onion.to].63vc4

Based on the research report, all the enciphered files appear to be 132 bytes larger as compare to it original version, after the encryption procedure is completed. Contrary to its previous version, Cry128 Ransomware uses a payment portal which is hosted on TOR and Tor2web links in order to make the ransom payment website more accessible for the less-skilled computer users. However, you should never try to pay the ransom money demanded by the virus developers. In this case, you can download the decryption tool from Emsisoft’s decryptor website, after removing the malware completely from your system.

Expert’s Conclusion

Experts explain that Cry128 Ransomware is only the outcome of destructive minded people’s exploration to create a means for monetizing themselves. Therefore it is needless to say that if any victimized user think to pay according to published ransom note then it would be only the wastage of money. In place of that users must backup their all important files and data to maintain these in safe condition. And also they should prefer the use of reliable anti malware tools to remove Cry128 Ransomware and to prevent PC from future attack.
