ATTENTION! JS.Crypto Ransomware (also known as Ransom32) is actively spreading on the Internet as a client.scr file. According to the victims, it is usually dispersed as a spam email attachment or may be executed once the PC user clicks on a Trojan infected advertisement/link. Once inside the system (can affect Windows, Linux, and Mac OS), it encrypts personal information, including photos, documents, music, etc. and them required to pay the ransom for getting them back. At the moment of writing, there is no other way to decrypt JS.Crypto Ransomware affected files except paying the required sum of money. Unfortunately, but disclosure of credit card details, full name, and another sensitive information to cyber frauds is a risky thing that can cause serious issues, such as thefts from your bank account, in the future.

Is JS.Crypto an ordinary ransomware?

Ransomware analysts warn that JS.Crypto is NOT an ordinary cyber threat. If ransomware virus that we already were known were typically targeting Windows platform and did not even look to the side of Linux or Mac OS, for now, users of these two platforms can also be affected.

JS.Crypto Ransomware infection

How does it work?

Regarding other performances of JS.Crypto virus, it seems to be similar to other ransomware type computer infections. Once it reaches a target system, it is installed to %Temp% and %AppData%\Microsoft\Windows\Start Menu\Programs\Startup directories and injected into Windows startup (ChromeService.lnk). Besides, to protect itself from being identified and removed easily, it creates files like chrome.exe, ffmpegsumo.dll, s.exe, msgbox.vbs, u.vbs, rundll32.exe, and many others. At the same time, JS.Crypto ransomware performs file encryption, which is why you may lose access to files having .jpeg, .mp3, .mpeg, .dot, .jpg, .pmd, .mp4, .sdf, .docx, .ppj, .3gp, .aet, and other extensions. On top of that, you may receive an alert claiming:

ALL YOUR PERSONAL FILES HAS BEEN ENCRYPTED

All your data (photos, documents, databases, etc.) have been encrypted with a private and unique key generated for this computer. This means that you will not be able to access your files anymore until they are decrypted. The private key is stored in our servers and the only way to receive your key to decrypt your files is making a payment.

As we have already pointed out, to decrypt files that have been jeopardized by JS.Crypto malware, you will have to pay the ransom. For now, the amount of money required is not big if compared to other ransomware infections. The required ransom is 0.1 Bitcoins (approximately $35) that has to be paid within four days. After that, the sum of money will increase twice or more. If you have already lost access to personal files and received JS.Crypto ransomware notification, you should remove JS.Crypto ransomware using Reimage or another professional anti-malware and then use file backups. In case you have never done backups, and then you may be in serious trouble because there is no tool for restoring files except paying the ransom. However, before paying the money, think twice because you may disclose your credit card details and other sensitive information to suspicious parties that may later initiate thefts straight from your bank account.

How this ransomware infects operating systems?

There are several means through which JS.Crypto virus is spread. It may be injected into fake software update prompts (Java, Media Player, VLC player, etc.), spam email attachments, suspicious third-party software, torrent files, and so on. That’s why it’s vital to stay away from questionable content. In most of the cases, people get tricked into installing JS.Crypto virus through spam email informing about missing payments, pre-paid purchases, taxes, and similar issues. Therefore, be careful and if you find the typo, grammar or other mistakes in the title or content of the message, do not open its attachment. Besides, to keep your PC virus free, install a professional anti-malware and keep it up-to-date. It will block infiltration of dangerous/potentially unwanted programs and keep your PC’s stability.

If, unfortunately, JS.Crypto ransomware is already lurking in your machine, make sure that you delete it ASAP. To find out more about JS.Crypto removal, go to the page 2.

    Another ransomware??? Jeez, those cyber frauds dont waste time.. I guess I need to make another backup since Im really scared of JS.Crypto encoding

  • Ian Werner

    This ransomware is yet another scary stuff. It seems that those infections are getting more and more powerful each day. Its actually strange that JS.Crypto ransomware asks for such a minimal payment. I believe that its just a matter of time when the ransom will increase

  • Adgio dazzle

    Is there a way to get the data back? does anyone knows? Today JS.Crypto ransom note appeared on my screen and then i checked whether I can open my files or not. Sadly, none of the pics, videos, and documents are available.

  • Bianca

    As far as I understand, there is no software that can help you to restore files… Sadly, most probably you will have to pay or forget about those personal files. Let us known what was your choice
