Yesterday and just before 6am, a trojan deployed it's program and managed to encrypt most of my system. (strangely, no files older than 2018)

The extensions of these files are : NUEHE.

There's a readme in each folder that reads:

All of your files are currently encrypted by CONTI strain. 

As you know (if you don't - just "google it"), all of the data that has been encrypted by our software cannot be recovered by any means without contacting our team directly. 
If you try to use any additional recovery software - the files might be damaged, so if you are willing to try - try it on the data of the lowest value.

To make sure that we REALLY CAN get your data back - we offer you to decrypt 2 random files completely free of charge.

You can contact our team directly for further instructions through our website :

Just in case, if you try to ignore us. We've downloaded a pack of your internal data and are ready to publish it on out news website if you do not respond. So it will be better for both sides if you contact us as soon as possible.

It also removed my installed AV software.

At this point I'm looking for a decryptor.  

I understand that this is a new one as Google has little information about it.  It being the "NUEHE" variant.

Does anyone have suggestions as to how I can decrypt these files?  My usual method of this isn't coming up zero (Kaspersky et al)

 

TIA.

@UrsanWelcome.

Please check this :

 

 

Thank you for that.  It’s stating “This ransomware has no known way of decrypting data at this time.”

What is the typical turnaround time for decryption methods to be developed?

@Ursan I have no idea how long it takes to create a  decryptor for a ransomware sample.  Also,  in a lot of cases  files can't be decrypted without the private key that is only known by the attacker.

Just checking to see if there’s been an update to this ransomeware and a decryptor.
