How to Remove Jett Ransomware [.jett Files Virus]?

Research on Jett Ransomware [.jett Files Virus]

Jett Ransomware, identified by its signature .jett file extension, is a hybrid-cryptography malware targeting Windows systems. Unlike traditional ransomware, Jett employs a dual AES-256 and RSA-4096 encryption algorithm, making decryption without the attacker’s private key nearly impossible. Initial infection vectors include phishing emails disguised as delivery notifications (e.g., “Your Amazon Package is Delayed – Invoice Attached”) and malvertisements on adult websites offering fake “video codec” downloads. Once activated, Jett virus disables Volume Shadow Copies, deletes backup files via vssadmin.exe delete shadows /all /quiet, and encrypts documents, images, databases, and even cloud-synced folders. Victims report ransom demands ranging from 0.5 to 2.5 BTC (≈$35,000–$110,000 as of March 2025) with a 24 or 48-hour deadline. .

Reports from Jett Virus Victims

“I attempted to install a pirated game, which unfortunately led to a virus infecting my PC. My father even went as far as formatting the computer, but once we turned it back on, we found that many important family files like photos, videos, and GIFs had been encrypted. Now, all these files have a .jett extension, and I can’t seem to fix it. These files are incredibly important to my family, including irreplaceable photos of my late grandmother. Is there any way to recover them? I really need some help with this.. A ransom note said, ‘You have to pay for decryption in Bitcoins!”

“About an hour ago, I downloaded and unzipped a file, then ran it with Microsoft Defender turned off. Shortly after, my laptop started lagging, and I noticed that my wallpaper had changed. Worse yet, most of my files are now encrypted with a .jett extension added to them. What should I do?. the hackers left a ReadMe.txt ransom note asking me to pay Bitcoin.

Jett’s File Encryption Logic

# Simplified Python-like pseudocode showing encryption flow
import os
from Crypto.Cipher import AES

def encrypt_file(path):
    key = os.urandom(32)  # AES-256 key
    iv = os.urandom(16)
    cipher = AES.new(key, AES.MODE_CBC, iv)
    
    with open(path, 'rb') as f:
        data = f.read()
    encrypted = cipher.encrypt(pad(data))
    
    new_path = path + ".jett"
    with open(new_path, 'wb') as f:
        f.write(iv + encrypted)
    os.remove(path)

*Example simplified for analysis. Actual Jett code uses polymorphic obfuscation.
