Randomware-like sample that can be easily modified and used. For educational purposes.
Features
- Highly portable. Should run on Windows/Linux/BSD.
- Opens a webpage to notify the user.
- Sends encryption key to a server.
- Store any necessary files in a zip archive appended to the executable.
- Uses RSA + AES128/256 CBC PKCS7.
- Works offline.
Usage
This software lacks several components that require a significant amount of work to implement. This is left upto the reader to do.
- Remove the safety pin.
- Compile the software.
- Create a webserver capable of processing requests from useless locker.
- Generate a private/public key pair using openssl or similar.
- Create zip archive of all the files in the required hierarchy.
- Append zip archive onto executable.
Appending the zip archive
Follow the instructions in the store README.
Legal
This is a fun peice of software that I enjoyed writing. I learned a few things while writing this and I hope that others can too. Please do not use this for ransomware or otherwise malicious purposes. This is only meant to be used for educational purposes.
