How does Gandcrab V5 encrypt a computer?

When GandCrab v5 is executed, it will scan the computer and any network shares for files to encrypt. When scanning for network shares, it will identify all shares on the network and not just mapped drives. Therefore, it is important to make sure all network shares are locked down on your network. When the ransomware encounters a targeted file, it will encrypt the file and then append a random 5 character extension.

What is GandCRAB Ransomware?

Let's take a deeper dive 

GandGRAB Ransomware was released in late 2016 and has since evolved to many different versions. The hackers behind GandCRAB are continuously updating and releasing improved versions, with currently six different variants being distributed as a Ransomware-As-A-Service(RAAS). This specific Ransomware uses several ways to spread itself through the systems, and some include using phishing emails and JavaScript Droppers.

GandCRAB ransomware is a Trojan horse that encodes files on the compromised computer and requests an installment to unscramble them. The new GandCrab V5 was released with random extensions and a new HTML ransom note.
