In this article, you will find more information about Cposysrzk ransomware virus as well as a step-by-step guide on how to remove malicious files from an infected system. One of the steps in our guide reveals how to potentially recover files encrypted by this ransomware.
Cposysrzk Ransomware
Cposysrzk ransomware is a malicious software developed to corrupt basic system settings and important data. Once loaded on a PC, the ransomware performs lots of malicious transformations that enable it to become persistent. Many personal files that store valuable information gets locked by Cposysrzk as it aims to extort a ransom payment from its victims. Since the encryption is realized with a strong cipher algorithm, encoded .cposysrzk files remain inaccessible. We advise victims to skip following the instructions listed in the HOW TO RESTORE YOUR FILES.TXT file.

Cposysrzk Virus – Spreading, Infection and Data Encryption
There are quite a lot of techniques that may be utilized for the spread of Cposysrzk ransomware virus. However, the main one is considered to be malspam – spam emails that contain malicious code. Malspam is a great opportunity for hackers to set massive spam email campaigns against users worldwide. The goal is to trick users into running malicious code on their devices by thinking that they are opening an important document or a legitimate website. To make users more prone to interact with the malicious elements, hackers set the emails to appear as if they are sent by a representative of a legitimate website, service, or governmental institution.
Security researchers identified that Cposysrzk cryptovirus belongs to the Snatch ransomware family. The threat is named after the malicious extension it appends to files it encodes.
When Cposysrzk ransomware loads on a computer system, it passes through several attack stages. At first, the virus is likely to create additional malicious files. Like most crypto viruses, Cposysrzk could place these files in the following folders:
- %Roaming%
- %Windows%
- %AppData%
- %Local%
- %Temp%
By executing malicious files, the ransomware corrupts system processes and stays invisible on the system. Since most of the affected system processes and components are essential for the regular performance, it is highly recommendable to consider the removal of all malicious files and objects associated with Snatch Cposysrzk ransomware as soon as possible.
While performing data encryption Cposysrzk virus utilizes a sophisticated cipher algorithm that transforms the code of target files. As a consequence, all corrupted files appear with the extension .cposysrzk appended to their names. The worst is that they remain inaccessible due to the changed code.
Unfortunately, all types of files which are typically used for the storage of important data could be encoded by this Snatch ransomware variant:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
At last, Cposysrzk ransomware drops a ransom note to blackmail victims into paying a ransom fee for the decryption of .cposysrzk files. Here is what the text stored in HOW TO RESTORE YOUR FILES.TXT reads:
Hello!
All your files are encrypted, write to me if you want to return your files – I can do it very quickly!
Contact me by email:
returndb@mail.fr or returndb@tfwno.gfThe subject line must contain an encryption extension or the name of your company!
Do not rename encrypted files, you may lose them forever.
You may be a victim of fraud. Free decryption as a guarantee.
Send us up to 3 files for free decryption.
The total file size should be no more than 1 MB! (not in the archive), and the files should not contain valuable information. (databases, backups, large Excel spreadsheets, etc.)
!!! Do not turn off or restart the NAS equipment. This will lead to data loss !!!To contact us, we recommend that you create an email address at protonmail.com or tutanota.com
Because gmail and other public email programs can block our messages!
Apparently, hackers urge you to send them an email message to the presented address so that they can send you further details on ransom payment. Beware, that even a successful ransom payment does not guarantee the recovery of your encoded files, so be advised to refrain from following hackers’ instructions before you attempt to solve the problem in a secure manner.

- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Cposysrzk Virus there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Cposysrzk Virus
Step 5: Try to Restore Files Encrypted by Cposysrzk Virus.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
