RansomwareSimulator

The goal of this repository is to provide a simple, harmless way to check your AV's protection on ransomware.

This tool simulates typical ransomware behaviour, such as:

Exfiltrating Documents (SMTP and/or FTP)
Creating/Deleting Volume Shadow Copies
Encrypting documents (I removed AES support just in case)
Dropping a ransomware note to the user's desktop

You can configure your simulation via appsettings.json

{
  "Config": {
    "ExtensionsToEncrypt": [ ".doc", ".docx", ".ppt", ".pptx", ".xls", ".xlsx", ".txt" ],
    "WorkingDirectory": "C:\\Users\\\\demo",
    "MaxFileSearch": 1,
    "FTPUser": "[email protected]",
    "FTPPassword": "xx",
    "FTPHost": "ftp://ftp.xx.xx",
    "SMTPServer": "smtp.gmail.com",
    "SMTPUser": "[email protected]",
    "SMTPPwd": "xxx",
    "SMTPSender": "[email protected]",
    "SMTPReciever": "[email protected]",
    "SMTPPort": 587,
    "CreateDeleteShadow": true
  }
}

ExtensionsToEncrypt: The file extensions the ransomware simulator will search and encrypt
WorkingDirectory: Where to search those files
MaxFileSearch: Number of files to encrypt

The ransomware simulator takes no action that actually encrypts files on the device beyond what it was told to, or deletes existing Volume Shadow Copies. However, any AV products looking for such behaviour should still trigger.

Each step, as listed above, can also be either disabled or "highly" configured. I recommand you have a look at the code before running it.

Every file is backed-up before encryption (just in case), it uses a simple XOR with the key 000. Every taken step is logged into RansomSimulator.log

Don't be stupid

You are responsible of what you will do with this, do not trust me read the code and be sure you understand what you are about to run.
