Polski Ransomware – Update April 2018
With the help of Google Translate, you can see some of the information posted on the https://nomoreransom.cert.pl/vortex/ page below.
District Prosecutor’s Office in Warsaw informs you that it conducts proceedings PO II Ds 129.2017 against Tomasz T. responsible, among others for encrypting computers using the Vortex / Flotera / Polski ransomware viruses.
The tool on this page will allow you to obtain a key that can recover encrypted files.
Please note that at this moment the tool does not have keys from all campaigns in which the software encrypting files was used in. As new security measures are added, new keys will be added, so please check files that you have not been able to recover regularly.
If you managed to decrypt the files using the key obtained on this site, we kindly ask you to submit a notification of suspected offense together with the prosecutor in the nearest place of residence for your Police unit with reference to the case file PO II Ds 129.2017 District Prosecutor’s Office in Warsaw.
If you have an e-mail message that the perpetrator sent to you a malicious file, please save it on a CD/DVD (along with full headers and attachments) and hand it over to the police as an attachment to the interrogation protocol. It will not be necessary to submit for examination the computer on which the files were encrypted.

Select or drag the encrypted file below to check if we have the key needed to decrypt it. The key recovery process can take about a minute. Only a small portion of the file will be sent.
Click and select the file or drag it here.
[EMPTY FIELD]
Currently selected file: (missing).
In case files are encrypted with one of the first versions of the Vortex ransomware, you can try using the tool created by Michael Gillespie from MalwareHunterTeam: VortexDecrypter-Michael_Gillespie.zip.
If you managed to recover the key:
The recovered key can be used to decrypt files using the free AES Crypt program. The recovered key from one file should decrypt all encrypted files on your PC.

Polski Ransomware – Infection
Polski ransomware might spread its infection with various methods. The payload file which initiates the malicious script for this ransomware is seen circling the Internet by some malware researchers. If you get that file onto your computer system and execute it – the system will become infected.
Polski ransomware might also distribute its payload file on social media and file-sharing services. Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary. You should read the tips for preventing ransomware found in the forum section.
Polski Ransomware – Description
Polski ransomware is also a cryptovirus. Malware researchers believe that it might be targeting mainly Polish-speaking people, as its ransom message is written in the Polish language. The extension .aes is appended to all files that become locked after the encryption process is set and done.
This is the screen with the ransom message that appears after encryption:
Polski ransomware could make entries in the Windows Registry to achieve persistence, and probably launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.
The ransom note will be saved in the following files:
- !!! – – ODZYSKAJ-PLIKI – – !!!.txt
- !!! – – ODZYSKAJ-PLIKI – – !!!.htm
The note is written in Polish and gives details about the restoration of your files and how to pay the cybercriminals. You can view the ransom message that loads after file encryption right here:
That ransom note reads the following:

The note of the Polski ransomware states that your files are encrypted with the AES 256-bit encryption algorithm. A ransom sum of 249 USD is demanded as payment for unlocking your data. You are given 72 hours by the ransom criminals to unlock your files, or else the ransom sum doubles in price. You should NOT under any circumstance pay the cybercriminals. Your files may not get restored, and nobody could give you any real guarantee for that. Furthermore, giving money to these criminals will likely motivate them to create more ransomware or do other criminal activities.
However, you should try to get those 2 files decrypted for free, because they might come in handy if an actual decrypter is released.
For the moment, no list with file extensions that the Polski ransomware seeks to encrypt is available, but files with the following extensions are the most logical to get encrypted:
→.7z, .bmp, .doc, .docm, .docx, .html, .jpeg, .jpg, .mp3, .mp4, .pdf, .php, .ppt, .pptx, .rar, .rtf, .sql, .tiff, .txt, .xls, .xlsx, .zip
Each file that gets encrypted will receive the same extension appended to every one of them, and that is the .aes extension.
The Polski cryptovirus is very likely to delete the Shadow Copies from the Windows operating system by utilizing the following command:
→vssadmin.exe delete shadows /all /Quiet
Read on through and check out what type of ways you can try to potentially restore some of your data.

Step 2: Uninstall Polski and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by Polski on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- 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 Polski 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 Polski
Step 5: Try to Restore Files Encrypted by Polski.
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.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and Polski aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
