What is Dharma-Good Ransomware
Dharma-Good Ransomware is typical representative of encryption viruses from Crysis-Dharma-Cezar ransomware family. New generation of the virus uses RSA-1024 encryption algorithm. This sample appends .good extension to affected files. Dharma-Good Ransomware adds complex extension, that consists of unique id, developer’s e-mail and .good suffix. As a result, file named 1.doc will be converted to 1.doc.id-{8-digit-id}.[{email-address}].good. Here is the list of extensions used on real computers to this moment:
- .id-{id}.[onecrypt@aol.com].good
After finishing the encryption process, malware creates text file (ransom note): RETURN FILES.txt in the folders with encrypted files and on the desktop. Here are the contents of main virus window and ransom note:

crypt1style@aol.com or crypt1style@keemail.meDharma-Good Ransomware developers can extort from $500 to $15000 ransom in BTC (BitCoins) for decryption. Usually, it is quite big amount of money, because hackers pay the commission to Dharma Ransomware as Service (RaaS) owners. Using cryptocurrency makes it impossible to track the payee. Besides, victims of such viruses often get scammed, and malefactors don’t send any keys even after paying the ransom. We do not recommend to pay any money to malefactors. Usually, after some period of time security specialists from antivirus companies or individual researchers break the algorithms and release decryption keys. Mention, that some files can be restored by using backups, shadow copies, previous versions of files or file-recovery software. Follow the guide below to remove Dharma-Good Ransomware and decrypt .good files in Windows 10, 8, 7 effortlessly.
How Dharma-Good Ransomware infected your PC
Dharma-Good Ransomware uses spam mailing with malicious .docx attachments. Such attachments have malicious macros, that runs when user opens the file. This macros downloads executable from the remote server, that, in its turn, starts encryption process. Virus can also use Remote Desktop services to infiltrate victim’s PCs. It is important to know, that this ransomware can encrypt mapped network drives, shared virtual machine host drives, and unmapped network shares. It is necessary to control access to network shares. After encryption, the shadow copies of the files are deleted by the command: vssadmin.exe vssadmin delete shadows /all /quiet. Virus assigns certain ID with the victims, that is used to name those files and supposedly to send decryption key. In order to prevent infection with this type of threats in future we recommend you to use SpyHunter 5 or Norton Antivirus.
