JokeFromMars virus is a representative of the most terrible viruses, that are ransomwares. It is a prototypical example of the breed. JokeFromMars ransomware uses the asymmetric encryption algorithm as its main weapon. This type of encryption distorts the data files in a way they cannot be read nor opened. The most valuable data you stored on your computer is turned into a pile of junk. Your access to the information you need is restricted. This is what ransomware viruses are developed for. Soon you are going to be blackmailed for money to regain access to your data. Before knuckling under to these hackers, read the article and find better ways to deal with the misfortune which has befallen on you.
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.
How does Your Computer Get Infected with JokeFromMars Ransomware?
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.
JokeFromMars file-encrypting virus can also spread in the manner, which is rather uncontrollable. This refers to visiting various questionable domains, such as porno sites, free gaming or gambling online platforms, etc. or even clicking on infected advertisements. In the latter case, even God will not help you, but an elaborate antivirus, such as Spyhunter, could.
