What is Good ransomware? And how does it implement its attack?
Good ransomware is a file-encoding virus and is one of the latest variants of the notorious Dharma ransomware. It uses a “.good” extension in marking the files it target. Apart from the extension it uses and its email address, there are no other notable changes in this new malware strain. Meaning to say, it uses the same pattern in implementing its attack as other variants of Dharma ransomware.
The moment it manages to infect a system, it will immediately create and download several malicious files to help it implement its attack. It also modifies the Windows Registry to achieve persistence. After that, it will encrypt files with the following extensions using the AES cipher.

Each of the encrypted files will have the .good extension, signifying the attack of Good ransomware. Victims are then informed about the attack using a ransom note contained in a file named “About .Good unlocking instructions.txt” that states:
“All FILES ENCRYPTED “RSA1024”

To prove that they really have the Good decryptor and to lure users into paying the ransom, developers of Good ransomware even offer to decrypt 1encrypted file for free. If you’re one of the victims of this ransomware, know that even if they offer to decrypt one file without any charge that does not mean that they can be trusted. The best way to deal with this crypto-malware is by removing it immediately and to try recovering the files using other free alternatives.
How is the payload file of Good ransomware distributed?
The same with its predecessors, the malicious payload of Good ransomware is disseminated using spam emails where an obfuscated file is attached. Once this obfuscated file is opened, it will run malicious scripts that allow it to drop the malicious payload into the computer. Thus, always be careful in opening emails and even more so, the attached files.
