Remove Hello Ransomware (Decrypt .hello Files)

On this post, you can gain knowledge about the notorious Hello ransomware virus. Also part of this page are Removal Guide, possible File Recovery of encrypted files, Ways to Protect the Computer, as well as Tutorial Video.

Hello ransomware is a file-coder virus. That being said, the tasks of this threat is to block the access of users to their very own files. It usually aims on locking usual files like documents, spreadsheets, presentations, photos, images, databases, zip files, and relevant data. Hello ransomware (WickrMe) will use a high-level type of cipher to encrypt the files and thus, it becomes inaccessible. Apart from the complex encryption technique, it appends the affected files with .hello file extension. As a result, the ordinary file photo.jpg will transform into photo.jpg.hello.

More about Hello ransom virus

There is actually another Hello ransomware that was first identified in August of 2020. It is a member of the notorious Xorist malware group. For this specific variant, the extortionists were using an alias CandieTodd or KevinDeloach and wanted to be contacted via email or WickrMe app.

Hello ransomware uses several deceiving tactics to enter the computer. In most instances, it spreads via spam emails, malicious installers like pirated apps and freeware, web injector, Trojan downloader, fake software update, and malicious online advertisements.

Social engineering attacks were also seen to be helpful in deploying Hello ransomware. Attackers are making use of hack social media accounts to send malicious links to contacts. When opened or executed, it will infect the computer with a Trojan that may progress into the ransomware infection if not eliminated at once.

File encryption by Hello virus

If computer got infected by Hello ransomware, all the important files of user will be in peril. The objective of this virus is to extort money from users and in order to accomplish this task, it will encrypt selected files. It uses a complex algorithm method to lock the files. Then, Hello ransomware will demand ransom money from victims by producing a note file containing the following message:

Oops, some files in your computer are encrypted! If you want to decrypt these files, you need to contact me and pay some fees. Then, I will give the decryption key and software.
File Name Extension: .hello

Contact Emails:
CandieTodd@tutanota.com
KevinDeloach@protonmail.com

Contact WickrMe Usernames:
candietodd
kevindeloach

Warning, please send mail to all mailboxes at the same time. If the email does not reply within 48 hours, please use WickrMe to contact me.
If you contact a security or data company and cause my account is blocked, you will never be able to decrypt these files.

Should you pay the ransom?

The exact amount requested by attackers is not specified in the ransom note. Hence, no matter the cost is, malware researchers do not suggest to pay the ransom money. There are so many instances that attackers do not comply with the agreement after receiving the payment from victims. In addition, because the majority of ransomware were poorly coded, it may permanently damage the file during the encryption process. In that case, it become irrecoverable and paying the ransom money is irrelevant.

Recover Files from Hello Ransomware Infection

On this section, we will provide ways to decrypt files infected with Hello 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 Hello 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 Hello 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 Hello 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 Hello 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 Hello. Instead, it restores files from backup copy.

Option 2: Use ShadowExplorer to restore files encrypted by Hello 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 Hello 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 Hello ransomware infection.
