Hello ladies and gentlemen.

I have found this forum randomly out of desperation and hope that someone could help me with a ransomware that has found its way to my computer.

All my pictures and documents have sentimental value only, which hurts to lose.

I have been investigating as deep as i could but couldn't find any relevant decrypter and/or solution.


So ive received the good old message that's been floating all over the net about the RSA4096 Cryptosystem etc.

All of my media files (pics, vids, aud, doc etc) are now encrypted and the names are just letters and numbers, whilst the extensions are 5 random letters and numbers.


Example of 3 files on my desktop:






These files were PDF files if i remember correctly.


I have a reason to believe that i was able to get rid of the ransomware itself, using a system restore (Windows 8.1) and a malwarebytes scan right after, just in case.


Everything is still on my computer, the only way im restoring back to factory defaults is when i know for sure, that there is nothing i can do to save my files.


Thank you very much.

Best regards.

You were most likely hit by CryptXXX 4.0, it renames files in such a manner. You may use the service in my signature to upload a ransom note and encrypted file to identify.

Yes it is correct dear sir, thank you for your quick suggestion though it also said that

"his ransomware has no known way of decrypting data at this time."


It is very unfortunate.

I do have 1 more question before i push the button.

As your service suggests, i will backup the encrypted files anyway, but what else should i back up with it?

When you discover that your computer is infected with ransomware you should immediately create a copy or image of the entire hard drive. Doing that allows you to save the complete state of your system (and all encrypted data) in the event that a free decryption solution is developed in the future. In some cases, there may be decryption tools available but there is no guarantee they will work properly since the malware writers keep releasing new variants in order to defeat the efforts of security researchers.

Imaging the drive backs up everything related to the infection including encrypted files, ransom notes and registry entries containing possible information which may be needed if a solution is ever discovered. The encrypted files do not contain malicious code so they are safe. Even if a decryption tool is available, they do not always work correctly so keeping a backup of the original encrypted files and related information is a good practice.

There is an ongoing discussion in this topic where you can ask questions and seek further assistance. Other victims have been directed there to share information, experiences and suggestions.Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. To avoid unnecessary confusion, this topic is closed.
