Writing A Simple Ransomware Using Python

Introduction: Ransomware is a program designed to prevent a user or organization from accessing files on their computers. It encrypts the files and demands a ransom for the decryption key; this places organizations and individuals in a position where paying the ransom is the easiest,  cheapest, and quickest way to regain access to their files. Some types of ransomware have added functionalities – such as data theft too. Recent ransomware attacks have impacted hospitals’ ability to provide crucial services and crippled public services in cities. Ransomware doesn’t need to be complex to cause damage, which makes it even more dangerous. Bad actors don’t require a strong knowledge of programming, either. In this article, I will explore how to write a simple ransomware using Python.  How it works: The ransomware code can be split into three parts, the directory crawler,  encryption,  and decryption. The first function crawls through all accessible directories....
