Paradise Ransomware decryption tool
We’re happy to announce a new
decryptor for Paradise Ransomware.
Paradise Ransomware, initially
spotted in 2017, has been aggressively marketed as a service to interested
affiliates. After infection, it checks whether the keyboard language is set to
Russian, Kazakh, Belarus or Ukrainian and, if so, exits without encrypting.
Otherwise, it encrypts files and deletes shadow copies to prevent the user from
After encryption, it displays a
The new Bitdefender decryptor can
restore the following file extensions:
. FC, . 2ksys19, . p3rf0rm4, . Recognizer, . VACv2, . paradise, . CORP, .immortal, . exploit, . prt, . STUB, . sev, . sambo
How to use this tool
Step 1: Download the decryption tool below and save it on
Download the Paradise Ransomware decryption
Note: This tool does not require an
active internet connection.
Step 2: Double-click the file (previously saved as
BDParadiseDecryptor.exe ) and allow it to run by clicking Yes in the UAC
Step 3: Agree to the End User License Agreement
We strongly recommend you also
select “Backup files” before starting the decryption process, in case anything
occurs while decrypting. Then press “Scan”.
The “test folder” must contain a
pair of original/encrypted files, which will be used to determine the
decryption key. It is essential that this folder only contain a pair of
original and encrypted files and both files should be at least 15 kb in
Users may also check the “Overwrite
existing clean files” option under “Advanced options” so the tool will
overwrite possible clean files present with their decrypted equivalent.
At the end of this step, your files
should have been decrypted.
If you encounter any issues, please
contact us at [email protected].
If you checked the backup option,
you will see both the encrypted and decrypted files. You can also find a log
describing the decryption process, in %temp%BDRemovalTool folder:
To get rid of your encrypted files
after decryption, just search for files matching the extension and remove them
in bulk. We do not encourage you to do this, unless you have
double-checked that your files can be opened safely and none of the decrypted
files are damaged.
Silent execution (via cmdline)
The tool can also be executed
silently via a command line. If you need to automate deployment of the tool
inside a large network, you might want to use this feature.
- -help –
provides information on how to run the tool silently (this information
will be written in the log file, not on console)
- start -
this argument allows the tool to run silently (no GUI)
- –path - this argument specifies the path to
- –test - this argument specifies the test path to
a pair of original/encrypted files
- o0:1 -
enables Scan entire system option (ignoring -path argument)
- o1:1 -
enables Backup files option
- o2:1 -
enables Overwrite existing files option
-path:”C:” -> the tool will start with no
GUI and scan C:
BDParadiseDecryptor.exe start o0:1 -> the tool will start with no GUI and scan the entire
BDParadiseDecryptor.exe start o0:1
o1:1 o2:1 -> the tool will scan the entire
system, backup encrypted files and overwrite present clean files
