How to know if Kaspersky RakhniDecryptor can decrypt your file
The Kaspersky RakhniDecryptor tool decrypts files that have been changed according to the following patterns:
- Trojan-Ransom.Win32.Conti:
- <file_name>.KREMLIN
- <file_name>.RUSSIA
- <file_name>.PUTIN
- Trojan-Ransom.Win32.Ragnarok:
- <file_name>.<ID>.thor
- <file_name>.<ID>.odin
- <file_name>.<ID>.hela
For decryption, the utility asks for the file of the !!Read_Me.<ID>.html type.
- Trojan-Ransom.Win32.Fonix:
- <file_name>.<original_file_extension>.Email=[<mail>@<server>.<domain>]ID=[<id>].XINOF

Trojan-Ransom.Win32.Rakhni creates exit.hhr.oshit file, where you can find an encrypted password to the user’s files. If it remains on the infected computer, deciphering will take considerably less time. In case exit.hhr.oshit file was removed, recover it with the help of software that recovers deleted files, then put this file into %APPDATA% folder and re-run utilite scan. You can find exit.hhr.oshit file following this path: C:\Users<user_name>\AppData\Roaming

How to decrypt files with Kaspersky RakhniDecryptor
- Download RakhniDecryptor.zip and extract the files from it. For instructions see this guide.
- Open the folder with the extracted files.
- Run the RakhniDecryptor.exe.
- Read the License Agreement carefully and click Accept if you agree to all its terms.
- Click the Change parameters link.
- Select the objects to scan (hard drives / removable drives / network drives).
- Select the checkbox Delete crypted files after decryption. In that case the tool will remove copies of encrypted files with extensions LOCKED, KRAKEN, DARKNESS etc.
- Click OK.
- Click Start scan.
- Select the encrypted file and click Open.
- Read the Warning and click OK.
Files will be decrypted.
File with CRYPT extension might be encrypted more than once. For example, if test.doc file was encrypted twice, the tool will decipher the first layer into the file test.1.doc.layerDecryptedKLR. In the tool performance report you will see: «Decryption success: disk:\path\test.doc_crypt -> dish:\path\test.1.doc.layerDecryptedKLR». You will need to decrypt this file once again. In case of successful decryption, the file will be saved under the original name test.doc.
Parameters for running the utility from the command line
For the sake of convenience and time saving, Kaspersky RakhniDecryptor supports the following command line parameters:
| Command name | Value | Example |
|---|---|---|
| –threads | To run the tool for multi-thread password cracking. If the parameter isn’t set, the number of threads equals the number of cores. | RakhniDecryptor.exe –threads 6 |
| –start <number> –end <number> |
To resume password cracking from a certain value. The lowest value is 0. To stop password cracking at a certain value. The highest value is 1 000 000. To crack the password in a range between two values. |
RakhniDecryptor.exe –start 123 RakhniDecryptor.exe –end 123 RakhniDecryptor.exe –start 100 –end 50000 |
| -l <file name woth full path to it> | To specify the file path, where the tool performance report must be kept. | RakhniDecryptor.exe -l C:Users\Administrator\RakhniReport.txt |
| /h | To display help for the command line options | RakhniDecryptor.exe -h |
