How to Use Avast Decryption Tool for HiddenTear Ransomware

The Avast Decryption Tool for HiddenTear is a free software utility designed to safely unlock files that have been locked up by the HiddenTear ransomware strain without requiring you to pay a cybercriminal ransom. What is HiddenTear Ransomware?

Open-Source Origins: HiddenTear was originally created in August 2015 as one of the first open-source ransomware codes hosted publicly on GitHub.

Widespread Variants: Though intended for educational purposes, cybercriminals stole the code to spawn hundreds of malicious spin-off variants.

Encryption Method: It utilizes standard AES encryption to lock data.

File Signature: When it infects your computer, it renames files by tacking on specific extensions like .locked, .lock, .bloccato, .razy, .krypted, and many others. How the Avast Decryption Tool Works

Because the original source code and subsequent variants had predictable coding implementations, cybersecurity researchers at ⁠Avast successfully reverse-engineered the math behind the lock mechanism.

No-Cost Solution: It is entirely free to download via the Avast Ransomware Decryption Tools Platform.

Saves Original Data: It safely reverses the AES encryption to give you back your documents, photos, and databases.

Simple Setup: Operating on a straightforward wizard interface, you simply feed the software a sample of an encrypted file alongside its original unencrypted version (if you have a backup of just one file) to help determine the key, then let it automatically scan and clean your storage drives. Steps to Take if You Think Your PC is Infected

Isolate the System: Instantly disconnect your PC from local Wi-Fi, networks, and cloud storage systems to stop the ransomware from spreading to other household devices.

Identify the Extension: Check the modified names of your locked files to confirm if they match HiddenTear signatures.

Remove the Malware First: Run a full system scan with a reputable security package like Avast Antivirus to fully purge the active ransomware virus script before running the decryption software.

Download the Decryptor: Grab the specific standalone tool directly from Avast or the ⁠No More Ransom Project Portal using a clean computer. Avast Blog
