# Laika # Laika
Laika is a simple botnet stack for red teaming. It allows authenticated communication across a custom protocol with generated key pairs which are embedded into the executable.

## Why 'Laika'? ## Why?
During the soviet space race, [Laika](https://en.wikipedia.org/wiki/Laika) was the first dog in space; however shortly after died of asphyxiation and overheating of the shuttle. Take whatever you want from this information. It's a fun project :)
## Would this work in real world scenarios?
My hope is that this becomes complete enough to be accurate to real botnet sources seen in the wild. However since Laika uses a binary protocol, the traffic the bot/CNC create would look very suspect and scream to sysadmins. This is why most botnets nowadays use an HTTP-based protocol, not only to 'blend in' with traffic, but it also scales well with large networks of bots where the CNC can be deployed across multiple servers and have a generic HTTP load balancer.
I could add some padding to each packet to make it look pseudo-HTTP-like, however I haven't given much thought to this.
## Configuration and compilation ## Configuration and compilation
Make sure you have the following libraries and tools installed:
- CMake (>=3.11)
- LibSodium (static library)
- NCurses
First, compile the target normally First, compile the target normally
