Ransom0 Ransom0 is an open source ransomware made with Python, designed to find and encrypt user data. the ransomware is organised in four parts: You need to have python3 installed and configured. A tag already exists with the provided branch name. If letft blank, Simple Python Ransomware will automatically target the Desktop. IMPORTANT: This tool is only for testing and academic purposes and can be used where strict consent has been given. A tag already exists with the provided branch name. Fixed handling of renaming files with adding/removing of the ransomware extension. For specific subirectories, specify the main directory first (ie. If nothing happens, download GitHub Desktop and try again. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. When the ransom is paid, a decryptor is provided. Allows recursive encryption of the target tree. Note that the key is the same one received in the email. Are you sure you want to create this branch? If used, the key will be stored in the same directory as ransomware.py. To review, open the file in an editor that reveals hidden Unicode characters. There is a private key to decrypt your data back, but you know that an attacker will not attach the private key to the virus. RSA Private key (to be removed). In the last articles, I have explained how making a python program to generate Private & Public key. To Convet the .py to exe You can use pyinstaller. python3 ransomware.py --d Downloads/Subdirectory ). Step 3 A python script to encrypt some files in the directory. Here is the test function to make sure that the function is working. To simulate a one-click malware, comment and uncomment the following: There is support for multiple paths, add them as such: This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. After running the genKey.py there are 2 files, private.pem and public.pem.Save your private.pem securely. python3 (python2 for Linux/macOS should work), Exfiltrate key back to C2 given domain and port, Ransomware Extension [default: .wasted for WastedLocker]. There was a problem preparing your codespace, please try again. Save your private.pem securely. To install Simple Python Ransomware, follow these steps: git clone git@github.com:mihneamanolache/Simple-Python-Ransomware.git && cd Simple-Python-Ransomware pip3 install -r requirements.txt Using Simple Python Ransomware Simple Python Ransomware is used both to encrypt and to decrypt files. If nothing happens, download GitHub Desktop and try again. Do not use it for illegal purposes! Warning: Be extra careful of running the program as it will modify files. Use Git or checkout with SVN using the web URL. You signed in with another tab or window. It has medium code complexity. I cannot be hold responsible for any file damage due to running this program on any machine. In the python script you can use this script: So, you can encode your private key, then decode it in the python script. Before running the script, head over to the .env file and update the following lines using your own information: After saving the file, you can run the script in the encryption mode by typing: --directory or -d takes as an parameter a string, which is the Location / Folder you are targeting (ie. Added autodetection on Windows, Linux or macOS. Learn more. Ransomware is malware that employs encryption to hold a victim's information at ransom. Only used for decryptor. If successful, the script will: . This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. The fernet module ensures that data encrypted using it can no longer be manipulated or read without the key. Work fast with our official CLI. the os library allows us to do operations on our files. The encrypted text is sent to the C2 server and displayed for the victim. I AM NOT RESPONSIBLE FOR ANY DAMAGED CAUSED BY THE ILLEGAL USAGE OF THIS PROGRAM. This highlights both the power of Python, but also the the ease of building such a virus. Here is my checklist, and you can use your own checklist. If nothing happens, download GitHub Desktop and try again. A tag already exists with the provided branch name. I originally added arguments to prevent accidental clicks and mess up. Lets scan the file, encrypt that, and then change the extension. The fernet module of the cryptography package has built-in functions for key generation, encryption of clear-text to cipher-text and decryption of cipher-to-clear text using the encryption and decryption methods respectively. I assume no liability and am not responsible for any misuse or damage caused by this tool and software in general. In a real world scenario, the attacker would have to deliver the key to the victim in order to decrypt the files. The idea I got from my last article about organizing files with python. A simple, fully python ransomware PoC using AES-CTR and RSA. USE AT YOUR OWN RISK! Put some files into this directory. Here is my directory before running malware: Here is my directory after running malware: We were able to make a python program for encrypting files and changing file extensions. In order to decrypt the files encrypted before, all you need to do is to pass the cryptographic key as a string to the program, as follows: You can retriev the cryptographic key either from the email sent before, or from the cryptographic_key.key file, if you used the --backup argument. --backup or -b doesn't take any parameter and is used to bypass the deletion of the cryptographic key from the system. If nothing happens, download Xcode and try again. For the testing, I wanna use the parent of this programs directory for scanning and encrypting with this script. Work fast with our official CLI. Just copy my script and paste it into the end of the malware script. Its like other malicious software or computer viruses, but with one purpose to encrypt your data and make a ransom for you. Simple Python Ransomware is a simple implementation of a ransomware in Python. In a nutshell, we are the largest InfoSec publication on Medium. There was a problem preparing your codespace, please try again. We had 16 amazing speakers who conducted super valuable and inspiring sessions. NB: As this is simply a PoC for Atomic Red Team, there is no real need to change the keys or other variables. Simple Python Ransomware is build in under 100 lines of code, mostly thanks to packages Cryptography (pip install cryptography) && python-dotenv, but also other packages (argparse, getpass, os, pathlib, smtplib, platform, email). For mitigation, this ransomware has Never trusted the file. Python-Ransomware saves you 49 person hours of effort in developing the same functionality from scratch. import os from cryptography.fernet import fernet # first step is to find all files in our current directory and store them in a list files = [] # next we'll use a for loop to add all files in the current directory to our files list for file in os.listdir(): if file == 'ransomware.py' or file == 'thekey.key' or file == 'decrypt.py': continue # we Step 4 Countdown and message after encrypting done. The program should be an executable file and the icon like a document file. If successfully decrypted you will receive the original plaintext as the result, otherwise an exception will be raised. And for the decrypt function, you can use my script before. Here is my full script, just copy it but dont forget to understand what you write. Before running the ransomware, you'll need to modify a few things in ransom.py: Put the url you've got when you started the server: I recommend running it in a testing directory, otherwise all of your files will be encrypted: Donations are welcome, it'll really help me to continue to maintain this project :), THIS PROJECT IS FOR EDUCATION PURPOSE ONLY, DO NOT RUN IT WITHOUT PERMISSION! Ransomware_python A simply python 3 Ransmoware in AES-128 bits HOW TO USE IT Create a test directory at the root of git directory Put some files into this directory Do the following command line to encrypt: python3 chiffre.py Do the following command line to decrypt: python3 dechiffre.py Then all your files in your test directory will be encrypted A tag already exists with the provided branch name. Encrypt all the files Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. The program must encrypt data with the public key, After encryption, the program must remove the original files and change the encrypted file extension with . You signed in with another tab or window. The result of this encryption is known as a Fernet token and has strong privacy and authenticity guarantees, Allows recursive decryption of the targeted tree structure. If nothing happens, download Xcode and try again. Desktop, Downloads etc.). It is safe to use this data immediately as Fernet verifies that the data has not been tampered with prior to returning it. Use Git or checkout with SVN using the web URL. This can lead to poossible file damage or loss.

Python executable: python3 RansomWare.pyz -t 5-d dir -e 64 YWFh # OR chmod u+x RansomWare.pyz # add execute rights./RansomWare.pyz aaa # execute file Python module (command line): . My recommendation is to read the guides and only run it on a virtual machine at your own risk. Apologies for my typo in the countdown timer :D. This is a scary project, right? python.plainenglish.io Develop the program Step 1 Generate Private & Public Key In the last articles, I have explained how making a python program to generate Private & Public key. Many Git commands accept both tag and branch names, so creating this branch may cause unexpected behavior. The updated code demonstrates a typical ransomware flow and it is just one of many ways to perform ransomware encryption. The 'Downloads' folder before the encryption. In order for the program to work from anywhere in the world, the server uses PyNgrok to tunnel it and make the server reacheable from evrywhere. The directory should be also specified using the -d argument, provided that it was used to encrypt files in directories other that Desktop. Files decrypted on all levels under 'Downloads': This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. TLDR: This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository. Your data is encrypted with asymmetric encryption, and the virus just encrypts with the public key. Just a Learner and CTFs Player on a quite night. Before you build some program, you must know about what it will be and what it will do. Program Structure: In order for the program to work from anywhere in the world, the server uses PyNgrok to tunnel it and make the server reacheable from evrywhere. The program must show a pop-up message with a countdown timer. The program will encrypt ALL files in thetargeted directory and its subdirectories. Supports Windows, Linux and macOS. Be careful when you execute the program, make sure you change the directory and try it in your Virtual Machine/Lab. The Infosec Writeups team just completed our first Virtual Cybersecurity Conference and Networking event. The project is built off CryptSky and full credits goes to deadPix3l for his code.

Tested with python 2.7 with pyinstaller 3.6 and python 3.7 with pyinstaller 4.0. A tag already exists with the provided branch name. With my program you could modify for the reverse, decrypting the .L0v3sh3 files. If you try to make real ransomware, you are breaking the law and you are going to jail. The attacker's embedded RSA public key (intentionally hardcoded in PoC) is used to encrypt the AES key. Decrypts a Fernet token. Please note that python 3.8 with pyinstaller 4.0 have known issues as this was incompatible with macOS. A simple python ransomware PoC that can be used for Atomic Red Team: ATT&CK Technique: Data Encrypted for Impact (T1486). If you want more explanation, just read my last articles. If you are using Windows as your Operating System, always turn on the extension view so you can differentiate which executable file or document file. Ransom0 is a open source ransomware made with Python, designed to find and encrypt user data. The private key is already stored in the attacker's C2 server. ATTENTION! Disclaimer:This tutorial is just for educational purposes, dont try to break any computer except yours. Are you sure you want to create this branch? A collection of write-ups from the best hackers in the world on topics ranging from bug bounties and CTFs to vulnhub machines, hardware challenges and real life encounters. Added RSA asymmetric encryption of the AES key. The main purpose of encoding is to make the public key hard to identify with static malware analysis.So, I encode the public key with base64 and attach that to my code. It has 129 lines of code, 7 functions and 2 files. code = "aGkgZnJpZW5kcywgdGhpcyBpcyBiYXNlNjQgZW5jb2Rpbmc=", https://dev.to/eshleron/how-to-convert-py-to-exe-step-by-step-guide-3cfi. I have authored articles about what we need to build ransomware. Encrypts data passed. Just change the encrypt function with decrypt with some logic. Use Git or checkout with SVN using the web URL.
