BKGHJ is a malicious program that encrypts the personal documents found on the victim’s computer with the “.[email@example.com].BKGHJ” extension, then displays a message which offers to decrypt the data if payment in Bitcoin is made. The instructions are placed on the victim’s desktop as a pop-up window and in the “readme-warning.txt” text file.

What is the BKGHJ ransomware?
BKGHJ is a file-encrypting ransomware infection that restricts access to data (documents, images, videos) by encrypting files with the “.[firstname.lastname@example.org].BKGHJ” extension. It then attempts to extort money from victims by asking for “ransom”, in the form of Bitcoin cryptocurrency, in exchange for access to data.
When you are first infected with the BKGHJ ransomware it will scan your computer for images, videos, and important productivity documents and files such as .doc, .docx, .xls, .pdf. When these files are detected, the ransomware will encrypt them and change their extension to “.[email@example.com].BKGHJ”, so that you are no longer able to be open them.
Once the BKGHJ ransomware has encrypted the files on your computer, it will display the “readme-warning.txt” text file that contains the ransom note and instructions on how to contact the authors of this ransomware.
This is the ransom note that the BKGHJ ransomware will show to its victims:
::: Greetings :::

Q: If I don’t want to pay bad people like you?
A: If you will not cooperate with our service – for us, its does not matter. But you will lose your time and data, cause only we have the private key. In practice – time is much more valuable than money.
DON’T try to change encrypted files by yourself!
If you will try to use any third party software for restoring your data or antivirus solutions – please make a backup for all encrypted files!
Any changes in encrypted files may entail damage of the private key and, as result, the loss all data.
If your computer is infected with this ransomware, we recommend that you contact the following government fraud and scam sites to report this attack:
- In the United States, go to the On Guard Online website.
- In Australia, go to the SCAMwatch website.
- In Canada, go to the Canadian Anti-Fraud Centre.
- In France, go to the Agence nationale de la sécurité des systèmes d’information
- In Germany, go to the Bundesamt für Sicherheit in der Informationstechnik website.
- In Ireland, go to the An Garda Síochána website.

- In the United Kingdom, go to the Action Fraud website.
- If your country or region isn’t listed above, we recommend that you contact your country or region’s federal police or communications authority.
Unfortunately, it is not currently possible to decrypt the files encrypted by the BKGHJ ransomware. It may, though, be possible in the future if the decryption keys are recovered from the cybercriminals’ servers. Therefore, if you do not plan on paying the ransom, it is advised that you make an image of the encrypted drives so that you can possibly decrypt them in the future.
Here is a short summary for the BKGHJ ransomware:
- Ransomare family: Xorist
- Extensions: .[firstname.lastname@example.org].BKGHJ
- Ransomware note: readme-warning.txt
- Symptoms: The images, videos, and other documents have the “.[email@example.com].BKGHJ” extension and cannot be opened by any programs
- Contact: firstname.lastname@example.org and email@example.com
How did the BKGHJ ransomware get on my computer?
The BKGHJ ransomware is distributed via spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed programs.
Here’s how the BKGHJ ransomware might get on your computer:
- Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link inside the email). And with that, your computer is infected with the BKGHJ ransomware.
- The BKGHJ ransomware was also observed attacking victims by exploiting vulnerabilities in the program installed on the computer or the operating system itself. Commonly exploited software includes the operating system itself, browsers, Microsoft Office, and third-party applications.

STEP 4: Restoring the files encrypted by the BKGHJ ransomware
Unfortunately, it’s not possible to recover the files encrypted by the BKGHJ ransomware because the private key which is needed to unlock the encrypted files is only available through the cybercriminals. However, below we’ve listed three methods you can use to try and recover your files.
Method 1: Search for a BKGHJ ransomware decryption tool
At the time of writing this article, there was no decryption tool available for the BKGHJ ransomware. However, the cybersecurity community is constantly working to create ransomware decryption tools, so you can try to search these sites for updates:
Method 2: Try to recover your files with Recuva Free
With this second option, we will install and try to recover the encrypted files with Recuva, a free data recovery tool.
Download Recuva Free.
You can download Recuva from the below link.RECUVA FREE DOWNLOAD LINK
(This link will open a new web page from where you can download Recuva Free)

Select the files you want to recover.
Recuva will scan your computer, and once it’s finished it will display a list of all the files that were detected. Select the check boxes beside the file or files you want to restore. The color of the dot next to the file name indicates your chances for a successful recovery (green for excellent, orange for acceptable, and red for unlikely).
Once you have selected the files you want to recover, click on “Recover”. Select a destination for the recovered files, then click on “Ok”.
Method 3: Try to restore your files with ShadowExplorer
The BKGHJ ransomware will attempt to delete all shadow copies when you first start any executable on your computer after becoming infected. Thankfully, the infection is not always able to remove the shadow copies, so you should continue to try restoring your files using this method.
You can download ShadowExplorer from the below link.SHADOW EXPLORER DOWNLOAD LINK
(This link will open a new web page from where you can download “ShadowExplorer”)
Double-click on the ShadowExplorer-x.x-setup file to start the installation process, then follow the on-screen promts to install this program.
Select snapshot date.
Open ShadowExplorer and then from the top bar select the drive where the files that you want to save are located, then select from the snapshot available one previous to this infection.
Export the files that you want to recover.
Once you have found a copy of the original file or folder, right-click on it and the select “Export”. A window will prompt you where you want to save the file or folder.
Your computer should now be free of the BKGHJ ransomware infection. If your current antivirus allowed this malicious program on your computer, you may want to consider purchasing the full-featured version of Malwarebytes Anti-Malware to protect against these types of threats in the future.
