Mobef crypto-virus emerges in the form of Kriptoki

Mobef virus[1] functions as a crypto-vrus via the executable Ransom.Mobef.A.exe. It encrypts files with DES, RSA and AES algorithms. The original version tended to append .keyx, .keyh0les or Lokmann.Key993 file extensions. 

After Mobef is done encrypting, it drops a ransom note, labeled date-of-infection-INFECTION.TXT (e.g.: 5-3-2016-INFECTION.TXT) or IMPORTANT.README.txt, to the folders of the computer, which contain infected files.

In this document, the victim is introduced to the current situation and provided with a solution to the issues: in exchange of the files, he/she has to pay 4 Bitcoins, which equals around $ 1,824.32.

The momsbestfriend@protonmail.com and torrenttracker@india.com email addresses are also provided in the note for further communication with the criminals. It is not recommended to pay the ransom since there is no guarantee that the perpetrators will return the data after remitting the payment.

Though the original version of the malware appeared last year, since then a couple of new versions have been introduced. They ceased appending distinguishable extensions. However, the latest version Kriptoki drops  KRIPTOKI.DONOTDELETE and PLEASEREAD.THISMSG files[2].

This new version also presents alternative email addresses: 

  • gaetano.olsen@protonmail.com;
  • gaetano.olsen@inbox.lv;
  • gaetano.olsen@india.com;
  • gaetano.olsen@pobox.sk;

This variation is known to target mostly Spanish and Turkish[3] users. However, residents of other countries should not let their guard as well. Unfortunately, neither of Mobef ransomware versions are decryptable. However, it you got infected with the malware, make a rush to remove Mobef. Reimage or Malwarebytes Anti Malware will be of assistance in this situation.

If your files are encrypted by Mobef, you can use several methods to restore them:

Data Recovery Pro method

This program is created for restoring damaged and lost files. However, it might come in handy dealing with Mobef crypto-malware as well.

The benefits of Shadow Explorer

Since there is no information whether this malware deletes shadow volume copies in advance, you might have a chance. The program uses these copies to create the copies of your original data.

  • Download Shadow Explorer (http://shadowexplorer.com/);
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Mobef Decrypter

At the moment, there is no viable decryption software released yet. Until then, let us discourage you from using the one promoted by the perpetrators.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Mobef and other ransomwares, use a reputable anti-spyware, such as Reimage, Plumbytes Anti-MalwareWebroot SecureAnywhere AntiVirus or Malwarebytes Anti Malware
