Goal

This cybersecurity project aims to understand how a malware works and focus on ransomware.In our case the program will only affect a small portion of the local files.

Since it's only a prototype, there's isn't any ransom to pay to decrypt the files. Plus, the program will only affect the files in the ~/infection directory and the spread will stay local.

The program is written in C++

Getting Started

Because it's a simple C++ project, there isn't much to say here

NOTE: Despite the fact that the program is an harmless malware, it's still a malware. So please, don't use it on your computer but on a virtual machine and more importantly don't use it for malicious purposes.

Prerequisites

Having a C++ compiler like c++

Installation

1. Clone the repo

   $> git clone https://github.com/Link-Wolf/stockholm.git

2. Compile the program

   $> cd stockholm
   $> make

3. Execute it

   $> ./stockholm [(-h|--help)|(-v|--version)] [(-s|--silent)] [(-r|--reverse) KEY]

   The -h (or --help) option is used to display the help message The -v (or --version) option is used to display the version of the program The -s (or --silent) option is used to run the program in silent mode and avoid the display of each file affected The -r (or --reverse) option is used to decrypt the files affected by the program. The KEY is the key used to decrypt the files
