A new decryptor for the RanHassan ransomware is now available for download. First isolated in May 2022, this family of ransomware seems to primarily target victims in India and Arab-speaking countries.
The tell-tale signs of a RanHassan infection are the presence of ransom notes called
[[email protected]](mailto:[email protected]) and
[[email protected]](mailto:[email protected]).
How to decrypt ransomed files
Step 1: Download the decryption tool below and save it on the infected device:
Step 2: Run the tool and accept the End User License Agreement.
Step 3: Select a folder to scan for encrypted files or let the tool find all files on the system. In order for the tool to identify the correct keys, you need at least one encrypted file and its unencrypted version.
Step 4: Start the decryption process and let the tool run until all files are decrypted.
Silent execution (via cmdline)
The tool can also be executed silently via a command line. If you need to automate the deployment of the tool inside a large network, you might want to use this feature.
-help – will provide 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)
-scan-path – this argument specifies the path containing encrypted files
-full-scan – will enable the Scan entire system option (ignoring -scan-path argument)
-disable-backup – will disable the file Backup option
-replace-existing – will enable the Replace previously decrypted files option
-test-path – specifies a folder containing pairs of clean-encrypted files
BDRanHassanDecryptTool.exe start -scan-path:C:\-> the tool will start with no GUI and scan C:\
BDRanHassanDecryptTool.exe start -full-scan-> the tool will start with no GUI and scan the entire system
BDRanHassanDecryptTool.exe start-full-scan -replace-existing -> the tool will scan the entire system and overwrite present clean files
