How to recover
Restore files encrypted by GandCrab 5
from Windows

Hello, my computer recently got infected with GandCrab 5 ransomware, and all files are encrypted! Hackers demand to pay the ransom. Although, I'm not willing to support ransomware attacks and pay the money. Are there any other ways how to restore files encrypted by GandCrab 5? I would really appreciate your help. Thank you. 

GandCrab 5 is a variant of the infamous GandCrab ransomware virus[ref en-2]. Even though the original version of the malware was discovered only in January 2018, it already has numerous new versions. This particular variant is also extremely dangerous and can encrypt all files stored on the system.

According to the researchers, GandCrab 5 encrypts data using Salsa20 and RSA 2048[ref en-1] ciphers. Encoded files are appended with a randomly generated extension of five letters. It is essential to understand that once the files are encrypted, they become unusable unless decrypted. 

Victims receive [randomly_generated_extension]-DECRYPT.html ransom note which includes information about GandCrab 5 ransomware attack. As usual, criminals demand to pay a specific ransom, but users must first contact them via TOR browser[ref en-3]. Such actions help hackers remain anonymous. 

However, as any IT experts would say, you should NEVER pay the ransom. If you follow the demands of the crooks, you only finance and support future cyber attacks. We know it might seem that there is no other possible way to decrypt files encrypted by GandCrab 5 ransomware. 

Luckily, our cybersecurity experts have prepared an easy step-by-step guide showing how to restore files encrypted by GandCrab 5 virus. You can find it at the end of this article. Note that the instructions consist of multiple methods, so try them all for the best results.
