Viruses

Dharma virus, unlike similar types of ransomware, does not change desktop background, but creates README.txt or Document.txt.[amagnus@india.com].zzzzz files and places them in each folder with compromised files. Text files contain message stating that users have to pay the ransom using Bitcoins and amount is approximately $300-$500 depending on ransomware version. The private decryption key is stored on a remote server, and there currently impossible to break the encryption of the latest version.

STOP Ransomware (aliases: DJVU Ransomware, Dalle Ransomware, Litar Ransomware, Lotep Ransomware, Nusar Ransomware) is extremely dangerous file-encrypting virus, that extorts money in exchange for decrypter. Ransomware utilizes strong AES-256 encryption algorithm and makes files unusable without decryption master key. Particular malware in this review appends .dalle, .lotep or .nusar extensions to files. As a result, file example.jpg converts to example.jpg.dalle, example.jpg.litar, example.jpg.lotep or example.jpg.nusar. STOP Ransomware creates special text file, that is called _readme.txt, where hackers give contact details, overall information about encryption and options for decryption. All latest versions of STOP Ransomware use typical behavioral pattern. They use anonymous TOR servers and cryptocurrency to receive ransom payments and that prevents police from tracking them. Cost of decryption is $980, but it can be $490 if victims pay within 72 hours. Cybercriminals even offer to decrypt one file for free, as a proof, that files can actually be decrypted. In most cases, STOP Ransomware encrypts files of each victim with a unique key, however, sometimes when the computer is not connected to the internet (or lost connection) or hacker's server is not responding, the malware creates "offline key". In this situation, utility called STOPDecrypter, developed by Michael Gillespie may be able to decode your data for free.

Recently, experts have observed the epidemic of the virus STOP Ransomware (also known as DJVU Ransomware). It is encryption virus, that uses strong AES-256 encryption algorithm to encrypt user files and makes them unavailable for the uses without decryption key. Latest versions of this pest add .vesad, .truke, .neras or .horon extensions to affected files. STOP Ransomware creates special text file, that is called "ransom note" and named _readme.txt. In this text file, malefactors provide contact details, overall information about encryption and options for decryption. Virus copies it on the desktop and in the folders with encrypted files.

Dharma-Html Ransomware is one of the types of encryption viruses based on the code of the family of Crysis-Dharma-Cezar ransomware. Version, that is under review today has certain differences. It adds .html extension to encrypted files and uses other e-mail addresses for communication. Dharma-Html Ransomware, as well as other latest Dharma variations, doesn't have decryptor, that can automatically decrypt encoded data. However, using instructions below can help you recover some files. Dharma-Html Ransomware creates suffix, that consists of several parts: prefix "id-", identification number (alphanumeric and unique for each computer), developer's e-mail address and .html extension. The pattern of the filename after encryption looks like this: file called 1.doc will be converted to 1.doc.id-{8-digit-id}.[{email-address}].html.

If your files recently got .myskle, .gerosan, .muslat or .boston extensions, that means your PC is infected with encryption virus called STOP Ransomware (alternative name is DJVU Ransomware, because first versions of virus of this type appended .djvu extension). This is very wide-spread and actively distributed malware. Ransomware initially used AES-256 encryption algorithm, and there was no way for decryption. However, if during encryption process infected PC was out of internet, or connection with remote server of hackers was interrupted your files can be decrypted using methods provided below. STOP Ransomware has a ransom note called _readme.txt. In this text file malefactors give contact information and details on how to make a payment. Virus copies it on the desktop and in the folders with encrypted files.
