Once the encryption procedure is done, it will create a ransom note called “CRAB-DECRYPT.txt” offering decrypt all users files if a payment is made. You can see an one of the variants of the ransomnote below:
---= GANDCRAB V3 =---
Attention!

4. Follow the instructions on this page
On our page you will see instructions on payment
and get the opportunity to decrypt 1 file for free.
The ransomnote offers victim to contact GandCrab V3’s developers in order to decrypt all personal files. These persons will require to pay a ransom (usually demand for $300-1000 in Bitcoins). We do not recommend paying a ransom, as there is no guarantee that you will be able to decrypt your documents, photos and music. Especially since you have a chance to restore your documents, photos and music for free using free utilities like ShadowExplorer and PhotoRec.
Unfortunately, at this time, victims of the GandCrab V3 virus cannot decrypt encrypted personal files without the actual encryption key.

How to decrypt encrypted files
Currently there is no available method to decrypt CRAB files, but you have a chance to restore encrypted documents, photos and music for free. The virus repeatedly tells the victim that uses a hybrid AES + RSA encryption mode. What does it mean to decrypt the files is impossible without the private key. Use a “brute forcing” is also not a method because of the big length of the key. Therefore, unfortunately, the only payment to the developers of the GandCrab V3 ransomware entire amount requested – the only method to try to get the decryption key and decrypt all your files.
There is absolutely no guarantee that after pay a ransom to the creators of the GandCrab V3 virus, they will provide the necessary key to decrypt your files. In addition, you must understand that paying money to the cyber criminals, you are encouraging them to create a new ransomware.
