The Emsisoft Planetary Decryptor is a free cybersecurity tool designed to unlock files encrypted by the Planetary ransomware family without paying a ransom. Developed by security firm Emsisoft in 2019, this standalone executable bypasses the attackers’ demands by reconstructing the encryption details directly on the victim’s machine. Identification of Planetary Ransomware
You can verify if your system was infected by this specific family by looking for these indicators:
File Extensions: The ransomware encrypts data using AES-256 and appends planetary or related extensions, including .mira, .yum, .Neptune, or .Pluto.
Ransom Note: A text file named !!! READ_IT!!!.txt is dropped onto the Desktop and inside every affected folder.
Attacker Emails: The note typically instructs victims to contact email addresses such as [email protected] or [email protected]. How to Use the Decryptor
Quarantine the Malware: Before decrypting, you must entirely remove or quarantine the active ransomware using an antivirus tool like Emsisoft Anti-Malware. Failing to do so will result in the malware repeatedly re-encrypting your files.
Download: Safely download the official executable file (decrypt_Planetary.exe) directly from the Emsisoft Ransomware Decryption Portal.
Admin Privileges: Right-click the downloaded file on your Desktop and select “Run as administrator” to give the tool full system access.
Submit the Ransom Note: Agree to the license terms, then click “Browse” to supply the tool with a copy of your specific !!! READ_IT!!!.txt ransom note. This helps the tool locate your unique victim ID.
Start Decryption: The tool will automatically pre-populate your connected hard drives. Click “Decrypt” to begin restoring your files. Critical Considerations
File Safety: By default, the decryptor enables an option to “Keep encrypted files”. It is highly recommended to keep this checked. Because the decryption process cannot perfectly guarantee 100% data integrity for every file type, keeping the locked copies ensures you do not lose data if a file becomes corrupted during recovery.
Cost: The tool is completely free. Technical support regarding its usage is provided natively to users holding a paid Emsisoft product license.
