GandCrab v5 has been released with a few noticeable changes. The most noticeable changes are that the ransomware now uses a random 5 character extension for encrypted files and has a HTML ransom note. The ransom amount is currently $800 USD to be paid in the DASH (DSH) cryptocurrency as can be seen below. There is no way to decrypt files encrypted by the ransomware for free. As always if you wish to discuss this ransomware or receive help with it, you can use our dedicated Gandcrab Help & Support topic.
