How to remove H@RM@ Ransomware

H@RM@ ransomware is a hazardous computer virus. The objective of this threat is to lock computer files particularly those that are important to users like .doc, .xls, .ppt, .jpg, .png, .pdf, .mp4, .mp3, .mov, .dwg, .zip, .rar, and many more. H@RM@ ransomware utilizes a complex algorithm method to encrypt the files and for that, it would be impossible for common computer users to recover the encrypted files. Aside from the applying the encryption, the virus also appends the data with strings of values like [01234567[recoverydata98@protonmail.com].H@RM@.

Mass mailing campaign is observed as the primary distributor of the H@RM@ ransomware. The virus is attached to an email message, which mimics the usual correspondence from legitimate organization. Because of this misleading trick, recipients are often influenced to execute the attached file that will initiate the H@RM@ ransomware attack.

First thing it will do is communicate to a command-and-control server to report the successful penetration. Then, it waits for the command and private key before launching the attack. Once obtained, H@RM@ ransomware begins encrypting the target files with complex technique, making it impossible to recover without the H@RM@ decryption tool. Lastly, the virus generates a ransom note called ReadMe.txt informing computer user of the current attack. In addition, the document provides instructions to recover the encrypted data and as usual, actors behind H@RM@ ransomware demands payment. Here is an excerpt from the ransom note:

ALL YOUR VALUABLE DATA WAS ENCRYPTED!
All your files were encrypted with strong crypto algorithm AES-256 + RSA-2048. Please be sure that your files are not broken and you can restore them today.
If you really want to restore your files, please write us to the emails:

Backup your files

One important step before proceeding with the procedures below is to backup your files. Ransomware are not the same. Each has its unique sets of payloads aside from encrypting the files with complex method. Others tend to delete the infected files after certain period, while others keep them concealed on hidden places. In addition, ransomware decryption tools are not guaranteed to be perfect, there are instances that files suffer from damages during the decryption process.

So, create a backup copy of your entire H@RM@ encrypted files right now.

H@RM@ Ransomware Removal Guide

First thing to do is remove the H@RM@ virus before attempting the decryption. Remember that as long as the ransomware is active, it will repeatedly encrypt the files on the compromised computer.

Infection of H@RM@ ransom virus is dangerous to the system because it can inject files that runs each time Windows starts. To prevent the malicious files from loading, Windows operating system must run with minimal process and it can be done through SafeMode With Networking.

Stage 1 : Temporarily Disable System Restore on Windows OS

Because H@RM@ and relevant virus is capable of reinstating itself by exploiting the System Restore of Windows, we suggests that you temporary disable System Restore while executing the steps. This option is also helpful to effectively run a full scan on the computer.

Recover Files from H@RM@ Ransomware Infection

On this section, we will provide ways to decrypt files infected with H@RM@ ransomware. Aside from dedicated decryption software and common tools, other options for file recovery are provided. As much as we can, we will update this area whenever there is new and more suitable decryption tool was made available.

Decrypting H@RM@ infected files with Emsisoft Tools

This service from Emsisoft is helpful in unlocking encrypted files without paying the ransom. It gives three ways to detect the ransomware and provide suitable recovery method:

Upload ransom note – This is usually the .txt or .hta files that was generated by H@RM@ ransomware.

Upload the encrypted file – The actual encrypted file. Choose the one that is less than 8MB in size.

Contact information – Enter the email address or any links provided as it appears in the ransom note of H@RM@ virus.

Emsisoft Tools

After submitting any of the appropriate data, Emsisoft will attempt to identify the ransomware and provide keys if there are available.

Option 1: Windows Previous Version Tool

Windows Vista and Windows 7 have a feature called Previous Versions. However, this tool is only usable if restore point was made prior to ransomware infection. To use this tool as "recovery option" for files encypted by H@RM@ virus, please follow these steps:

1. Open My Computer or Windows Explorer.

2. Right-click on the affected files or folders. From the drop-down list, please click on Restore previous versions.

3. New window will open display all backup copy of files and folders you wanted to recover. Choose the appropriate file and click on Open, Copy, or Restore. Restoring selected files overwrites the current locked files on the computer. The tool is not actually recovering files encrypted by H@RM@. Instead, it restores files from backup copy.

Option 2: Use ShadowExplorer to restore files encrypted by H@RM@ Ransomware

Just like Previous Version tool, ShadowExplorer is taking advantage of shadow copy created by Windows. This tool allows you to retrieve older version of files before it was encrypted by H@RM@ ransomware.

1. Download ShadowExplorer from the official web site.

2. Install the program with the default settings.

3. The program should run automatically after installation. If not, double-click on ShadowExplorer icon.

4. You can see the drop-down list on top of the console. Please select proper drive and the most recent point-in-time shadow copies of files you wish to restore prior to H@RM@ ransomware infection.

5. Right-click on the Drive, Folder, or File you wish to restore and click Export...

6. Lastly, ShadowExplorer will prompt for location where you want to save the copy of recovered files.

How to protect the computer from H@RM@ ransomware?

After the removal of the ransomware, it is important to prevent similar incident from happening again. In order to protect the computer effectively, computer user must know how H@RM@ ransomware was able to infect the computer. To minimize the possible infection, staying away from the common sources of this virus is crucial.

How H@RM@ ransomware can infect your computer?

The method of infecting the computers was found to be similar as other common viruses. Though, ransomware like H@RM@ is seen to have efficient deployment via spam email messages, web injectors, malicious software installers, misleading online advertisements, and through another virus infection.

Once the virus is executed, it immediately infects the system. Then, H@RM@ ransomware communicates to remote server so that unique key can be generated for the specific computer. After acquiring the key, it starts to decrypt target files using a complex method that is almost unbreakable. On the last stage of the attack, H@RM@ ransomware demands for ransom money as payment for the decryption tool. To further understand the attack scheme, we have included an infographic below.
