JokeFromMars virus is a representative of the most terrible viruses, that are ransomwares. It is a prototypical example of the breed.

About JokeFromMars Ransomware

JokeFromMars ransomware benefits from the AES encryption. The text, audio and video files, images and other file types are encrypted with the asymmetric encryption algorithm. And the victim can no longer freely use his (her) own documents. In fact, he/ she practically loses them. Whether JokeFromMars crypto virus appends any extension to the encrypted files or not, is still not clear. But it does replace your desktop wallpaper with its ransom note for sure:

As you can see, there is also a pop-up window placed on it, as if it wouldn’t be enough to undertake the screen alone. The ransom message does also appear as a text file, named ReadMeFilesDecrypt!!!.txt, in every folder, which has undergone the attack. The note states that 96 hours or 4 days is the deadline for paying the ransom, which is 1.1 BTC (bitcoins) equaling to 668.63 USD at this particular point in time. The specific BTC address is 3NTf83A3cfPPU3anWioSTYdgRSi2YMhcsx, to which the ransom payment is supposed to be transferred. The cyber crooks behind JokeFromMars cryptomalware provides links to Tor sites, where the payment is supposed to be carried out. They do also provide service of the encryption of 5 random files free of charge. However, we advise you not to get inveigled into communicating with these cyber criminals. Even if they do actually have the working decryptor, there is no guarantees that you will receive it, even after having paid them.

JokeFromMars crypto-malware harnesses spam e-mails to make you yourself download and execute it on your device. Of course, you are not aware about that. You think that you are opening some important e-mail sent by a legitimate institution, such as The State Tax Inspectorate, for instance, informing about, let’s say, your debt or anything similar. But if you rewound the tape, you should face the fact that you opened a spam e-mail, which alone should have warned you that there is something suspicious about the notice. Whenever you receive such spam e-mails, it is better to delete them without even opening or, for God’s sake, following the links or clicking on the attachments added.

Step 3. Restore JokeFromMars Ransomware affected files using Shadow Volume Copies

If you do not use System Restore option on your operating system, there is a chance to use shadow copy snapshots. They store copies of your files that point of time when the system restore snapshot was created. Usually MarsJoke Ransomware tries to delete all possible Shadow Volume Copies, so this methods may not work on all computers. However, it may fail to do so.

Shadow Volume Copies are only available with Windows XP Service Pack 2, Windows Vista, Windows 7, and Windows 8. There are two ways to retrieve your files via Shadow Volume Copy. You can do it using native Windows Previous Versions or via Shadow Explorer.

a) Native Windows Previous Versions

Right-click on an encrypted file and select PropertiesPrevious versions tab. Now you will see all available copies of that particular file and the time when it was stored in a Shadow Volume Copy. Choose the version of the file you want to retrieve and click Copy if you want to save it to some directory of your own, or Restore if you want to replace existing, encrypted file. If you want to see the content of file first, just click Open.

Step 4. Use Data Recovery programs to recover JokeFromMars Ransomware encrypted files

There are several data recovery programs that might recover encrypted files as well. This does not work in all cases but you can try this:

  • We suggest using another PC and connect the infected hard drive as slave. It is still possible to do this on infected PC though.
  • Download Data Recovery Pro (commercial)
  • Install and scan for recently deleted files. Data Recovery Pro

Note: In many cases it is impossible to restore data files affected by modern ransomware. Thus I recommend using decent cloud backup software as precaution. We recommend checking out Carbonite, BackBlaze, CrashPlan or Mozy Home.
