Dharma-Good Ransomware is typical representative of encryption viruses from Crysis-Dharma-Cezar ransomware family. 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. Dharma-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.

How to remove STOP (DJVU) Ransomware and decrypt .bufas, .ferosas, .dotmap or .radman files

Standard

STOP Ransomware (DJVU Ransomware) continues its malicious activity in May, 2019, and now adding .bufas, .ferosas, .dotmap or .radman extensions to encrypted files. Malware aims most important and valuable files: photos, documents, databases, videos, archives and encrypts them using AES-256 algorythms. Encrypted files become unusable and cybercriminals start extorting ransom. Ransomware creates _readme.txt file, that is called “ransom note”, on the desktop and in the folders with encrypted files. Hackers demand $980 for decryption of your files (message states, that victims will get 50% discount if they’ll contact cyber criminals within 72 hours after the encryption). According to many reports, malefactors often don’t reply to victims, when they receive ransom payment. We strongly do not recommend paying any money. Files encrypted by some versions of STOP (DJVU) Ransomware can be decrypted with help of STOPDecrypter. Dr.Web specialists decrypted files encrypted with some variants of STOP Ransomware in private. Dr.Web does not have a public decoder. Before trying to decode the files, you need to stop active process, and remove STOP Ransomware.
