How to remove Dharma-Html Ransomware and decrypt .html files

What is Dharma-Html Ransomware

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. Here is the list of extensions discovered on ID-Ransomware to this moment:

• .id-{id}.[paydra@cock.li].html

After encryption, virus drops text file (ransom note): RETURN FILES.txt in the folders with encrypted files and on the desktop. The file contains contact details. Ransomware windows and ransom note have the following content:

Hackers may demand quite a big ransom (from $5000 to $15000) from the victims because they pay commissions to the developers of the initial code. Dharma Ransomware works as Ransomware-as-Service (RaaS) and can be used by any user, who can modify some parameters and make new ransomware from it. Using cryptocurrency and TOR-hosted payment websites makes it impossible to track malefactors. Besides, victims of such viruses often get scammed, and malefactors don’t send any keys even after paying the ransom. Unfortunately, manual or automatic decryption is impossible unless ransomware was developed with mistakes or had certain execution errors, flaws or vulnerabilities. We do not recommend to pay any money to malefactors. Often, after some period of time security specialists from antivirus companies or individual researchers decode the algorithms and release decryption keys. Some files can be restored by using backups, shadow copies, previous versions of files or file-recovery software. Complete the steps, provided on this page, to remove Dharma-Html Ransomware and decrypt .html files in Windows 10, 8, 7 effortlessly.

How Dharma-Html Ransomware infected your PC

Dharma-Html Ransomware uses spam mailing with malicious .docx attachments. Such attachments have malicious macros, that runs when the user opens the file. This macros downloads executable from the remote server, that, in its turn, starts the encryption process. The 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.
