The Avast Decryption Tool for EncrypTile Ransomware is a free security tool created to help victims unlock files encrypted by the EncrypTile ransomware strain without paying a ransom. Originally released after cybersecurity researchers cracked the ransomware’s mechanics, the utility specifically targets the AES-128 encryption algorithm used by EncrypTile. Overview of EncrypTile Ransomware
Origins: First observed in November 2016, with a finalized variant emerging in mid-2017.
Encryption Type: Uses AES-128, utilizing an encryption key that remains constant for a specific PC and user configuration.
Active Defense: While running on a computer, the malware actively attempts to block the user from launching administrative tools or antivirus programs that could eliminate it. How to Safely Bypass the Malware and Use the Decryptor
Because the ransomware actively fights back and prevents the user from launching security utilities, you must use a specific “file-renaming” workaround to trick the malware’s active processes.
Download the Official Tool: Navigate to the official Avast Free Ransomware Decryption Tools Directory and download the EncrypTile utility executable to your desktop.
Clone the File: Right-click the downloaded tool (or use Ctrl+C and Ctrl+V) to make a duplicate copy on your desktop.
Rename the Executable: Rename the newly duplicated copy to a critical system file name such as notepad, lsass, mspaint, or osk. This tricks the active ransomware process into ignoring the tool.
Initialize Neutralization: Run the newly renamed file. The wizard will detect the live ransomware threat, neutralize its blocking mechanism, and prompt you to reboot.
Reboot and Finalize Decryption: Restart your computer. Once Windows loads, the ransomware screen will be gone (though the ransom wallpaper may remain). You can then reopen the original Avast tool to decrypt your directory structure normally. Standard Wizard Flow
Once the blocking mechanisms are removed, you can navigate the program using the standard steps outlined in the Avast Decryption Guide:
Select Drive Locations: You will choose which local, network, or attached drives the utility needs to scan.
Backup Option: The utility will offer an option to back up encrypted files prior to starting. It is highly recommended to leave this checked in case of unforeseen file corruption during the data reversal process.
