Hi there,


We got infected with ransomware back in June that changed all of the files to the following:




After scouring this site and others, we could not find any existing decryption tool and it totally wiped all of our backups - we now have cloud backup going forward to prevent this.


We paid the ransom and the criminal sent us the decryption tool which we ran but although it seemed to run for a while, nothing was decrypted.

When we told this to the criminal he said it should work and asked us to send a sample file for him to test on - I sent a generic JPG that comes with Windows and since then he has ignored our emails.


At first I thought that he just was playing with us but why would he ask for the sample file then? Just to continue playing with us?


If I post the decryption tool he gave us would anyone be able to help us?


The customer is a not for profit school that we provide IT support for free as a kindness to them.

Any help would be much appreciated.

If you have the original malware that caused this, it would be the most helpful. I believe this is CryptoMix, also known as CryptFile2. You may share a few encrypted files and anything they gave you, we can try to take a look.

Sorry for the delay - the email went to my junk mail -just whitelisted bleepingcomputer


I just submitted the test file - it was originally tulips.jpg which I think comes with Windows.

I also submitted the decryption tool the criminal sent that didn't work as both the original RAR he sent me as well as the EXE that I extracted from the original RAR.


Also, just FYI, Grinler posted this about .SCL files back in March - not sure if it's relevant as I guess they can change the extension to whatever they want:



Thanks again

Also just submitted an unencrypted tulips.jpg from another PC to help you - not sure if it does but figured it doesn't hurt

Any files that are encrypted with CryptoMix Ransomware (CryptFile2) will have an <id number>.<email>_.code or <id number>.<email>_.scl extension appended to the end of the encrypted data filename and leave files (ransom notes) named HELP_YOUR_FILES.HTML, HELP_YOUR_FILES.TXT.

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. To avoid unnecessary confusion, this topic is closed.
