A Ransomware with a symmetric encryption algorithm (Fernet) - Made in 15 minutes.
This malware will list all the files in the C: Drive, and return a list with the files, and then encrypt the files one by one. I have not tested it on my own PC, but if something does not work, please send me an email - roeil4939@gmail.com
You need a basic knowledge and experience with Python, and a basic knowledge with Encryption and Decryption, and you need to install requests and cryptography modules, in order to download the images and use the Fernet algorithm.
$ pip install requests
$ pip install cryptography
