How to Uninstall Zhen Ransomware to Avoid Further Encryptions

Zhen is a malicious program that belongs to the ransomware category. Such programs encrypt the data on your computer and demand a ransom amount in exchange for the decryption tool. It is often challenging to recover your data without having a proper decryption tool and private key, and unfortunately, these cybercriminals are the only people to have it. Some more similar ransomware programs are KolzAnon, and Microsft(xorist).

You can also notice that this program renames the compromised files by adding the “.zhen” extension to the original filenames. For instance, it would rename a file titled “Test.jpg” to “Test.jpg.zhen” after encryption. Later, the program creates a ransom note titled “read.ini” in compromised folders. Similar information also appears in a pop-up window. 

The note informs you that the ransomware program has encrypted your files. It also assures you that you can recover your files by getting the decryption tool. However, you have to pay 0.3 bitcoins to the cybercriminals. In the current exchange rate, the amount converts to 3000 USD. Keep in mind that the bitcoin value fluctuates continually. 

However, these cybercriminals often abandon the conversation soon after receiving the payment. Thus, you might end up facing a financial loss adding to the data loss. Therefore, we highly advise you not to pay any money to these cybercriminals.

Besides, it is vital to uninstall the Zhen ransomware to avoid further encryptions. We recommend using a robust antimalware application for the task. It can easily detect and remove any malicious program from your computer. Moreover, it would defend your system from similar threats in the future as well.

This guide was written to help you remove the infection itself from your computer, and if a 100% proven method to recover the encrypted files is found we will update this guide.

We cannot help you recover your files and we can only recommend that you use ShadowExplorer or free file recovery software to restore your documents.

1. How did the Zhen ransomware get on my computer?

The Zhen ransomware is distributed via spam email containing infected attachments or by exploiting vulnerabilities in the operating system and installed software.

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 embedded inside the email). And with that, your computer is infected with the Zhen ransomware.

This ransomware was also observed attacking victims by hacking open Remote Desktop Services (RDP) ports. The attackers scan for the systems running RDP (TCP port 3389) and then attempt to brute force the password for the systems.


2. What is Zhen ransomware?

  • Ransomware family: Unknown
  • Extensions: .zhen
  • Ransom note: read.ini
  • Ransom: 0.3 Bitcoins
  • Contact: Not Provided

This Zhen ransomware variant restricts access to data by encrypting files with the .zhen extension. It then attempts to extort money from victims by asking for “ransom”, in form of Bitcoin cryptocurrency, in exchange for access to data.

This ransomware targets all versions of Windows including Windows 7, Windows 8.1 and Windows 10. Zhen ransomware searches for files with certain file extensions to encrypt. The files it encrypts include important productivity documents and files such as .doc, .docx, .xls, .pdf, among others. When these files are detected, this infection will change the extension to .zhen, so they are no longer able to be opened.

The Zhen ransomware changes the name of each encrypted file to the following format: .zhen.

Files targeted are those commonly found on most PCs today; a list of file extensions for targeted files include:

.sql, .mp4, .7z, .rar, .m4a, .wma, .avi, .wmv, .csv, .d3dbsp, .zip, .sie, .sum, .ibank, .t13, .t12, .qdf, .gdb, .tax, .pkpass, .bc6, .bc7, .bkp, .qic, .bkf, .sidn, .sidd, .mddata, .itl, .itdb, .icxs, .hvpl, .hplg, .hkdb, .mdbackup, .syncdb, .gho, .cas, .svg, .map, .wmo, .itm, .sb, .fos, .mov, .vdf, .ztmp, .sis, .sid, .ncf, .menu, .layout, .dmp, .blob, .esm, .vcf, .vtf, .dazip, .fpk, .mlx, .kf, .iwd, .vpk, .tor, .psk, .rim, .w3x, .fsh, .ntl, .arch00, .lvl, .snx, .cfr, .ff, .vpp_pc, .lrf, .m2, .mcmeta, .vfs0, .mpqge, .kdb, .db0, .dba, .rofl, .hkx, .bar, .upk, .das, .iwi, .litemod, .asset, .forge, .ltx, .bsa, .apk, .re4, .sav, .lbf, .slm, .bik, .epk, .rgss3a, .pak, .big, wallet, .wotreplay, .xxx, .desc, .py, .m3u, .flv, .js, .css, .rb, .png, .jpeg, .txt, .p7c, .p7b, .p12, .pfx, .pem, .crt, .cer, .der, .x3f, .srw, .pef, .ptx, .r3d, .rw2, .rwl, .raw, .raf, .orf, .nrw, .mrwref, .mef, .erf, .kdc, .dcr, .cr2, .crw, .bay, .sr2, .srf, .arw, .3fr, .dng, .jpe, .jpg, .cdr, .indd, .ai, .eps, .pdf, .pdd, .psd, .dbf, .mdf, .wb2, .rtf, .wpd, .dxg, .xf, .dwg, .pst, .accdb, .mdb, .pptm, .pptx, .ppt, .xlk, .xlsb, .xlsm, .xlsx, .xls, .wps, .docm, .docx, .doc, .odb, .odc, .odm, .odp, .ods, .odt

Once your files are encrypted with the .zhen extension, this ransomware will create the read.ini ransom note in each folder that a file has been encrypted and on the Windows desktop.
When the infection has finished scanning your computer it will also delete all of the Shadow Volume Copies that are on the affected computer. It does this so that you cannot use the shadow volume copies to restore your encrypted files.


3. Is my computer infected with Zhen Ransomware?

When Zhen ransomware infects your computer it will scan all the drive letters for targeted file types, encrypt them, and then append the .zhen extension to them. Once these files are encrypted, they will no longer able to be opened by your normal programs. When this ransomware has finished encrypting the victim’s files, it will create a read.ini text file which includes instructions on how to recover the files.

Below is the message that you will see in the read.ini file:

4. Is it possible to decrypt files encrypted with the Zhen ransomware?

The security companies and government officials often release decryptors for ransomware. You can take help of these decryptors to decrypt your encrypted files by Zhen ransomware.

However, it is not necessary that decryptors are available for kind and type of the ransomware you got infected. Especially if the ransomware is new and widespread, then it is most likly that you won't find decryptors for it. If it is an old and popular ransomware then you might find the decryptors.

The first step towards finding the decryptor is to know the acutal name and type of ransomware you get infected. To do that you can take help of NoMoreRansom.org. Visit the website and paste the ransom note in box provided. You can also upload the encrypted file to know the ransomware name. Once you do that click on GO! FIND OUT button.

Now the website will tell you about the type of ransomware and also provide you link if there is a decryptor available.

ID Ransomware is a similar website, you can upload the ransom note, sample encrypted file, or the contact email address to know about the type of ransomware. Once you know about it you can find the decryptors on the internet. But do not download decryptors from shady websites they may further infect your computer.

If you haven't find the decryptors then it is not possible to get your files back. That doesn't mean you should pay ransom to the cybercriminals. Do not pay any money to recover your files. Even if you were to pay the ransom, there is no guarantee that you will regain access to your files.

If you’ve already paid the ransom, immediately contact your bank and your local authorities. If you paid with a credit card, your bank may be able to block the transaction and return your money.
You can also contact the following government fraud and scam reporting websites:

If your country or region isn’t listed here, we recommend that you contact your country or region’s federal police or communications authority.
