Polski Ransomware – Update April 2018

Update! CERT.PL – the Computer Emergency Response Team of Poland, have issued a statement about a decryption tool available for the ransomware described in this article.

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.

– District Prosecutor’s Office in Warsaw

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 – 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.
